Thats funny that would mean the earth was formed by nothing if there is nothing but us nature and stars or just accept that there is a maker who made everything your whole body too just so he can love you. He is God seek Jesus and make sure we are alone please repent
@@StinkyGreenBud oh, come on! An invisible, angry, mass murdering sky daddy with abandonment issues that has a jewish zombie for a son (that was conceived by raping a child) makes perfect sense! Get your shit together, man!

Kurzgesagt's content, especially their more recent stuff, is absolutely amazing. They have plenty of videos that WILL give you that existential crisis feeling.
humans can't get along with each other but still convince themselves that talking to an alien species would go smoothly, still, this is the type of topic that I could honestly talk for hours
no idea what your on about, I am a human and get along with nearly everyone I know :). Kalashboy for interplanetary relations, I will take my pension immediately.
@@NoProtocol There's a really fantastic short, on Dust. About a down and out Lawyer who is kidnapped and made to represent Earth in negotiations with a Inter-galactic agency, the acting and writing are superb. th-cam.com/video/rv8kOzRZK8g/w-d-xo.html&ab_channel=DUST
Right, even the most "foreign" human shares so much of a common frame of reference that it is actually possible for people to learn new languages through immersion. We all are wired to be able to learn language, we see in largely the same spectra, can hear largely the same frequency ranges, and so on. In spite of that, small differences in cultures and values have caused massive conflicts. How would we even establish a handshake, so to speak, with an alien species? As it stands we'd likely have to use some sort of statistical analysis on communications received (if we're lucky enough to be able to perceive them at all) and for that we'd be depending on AI...
One of my most favorite Kurzgesagt videos is their animation of the short story "The Egg" by Andy Wier, definitely caused some existential reflection on my entire life. The concept of the story both changed and reaffirmed my worldview, and I feel the philosophy of the story is a very beneficial mindset to take on.
One way they estimate galactic size is by their gravitational effects. We may better know the masses involved than in the number of objects that mass is divided into.
And not just the gravity from visible matter you have to counter in the effects of dark matter to get an accurate reading for the gravitational effects of a galaxy too.
Could you do a high resolution spectral analysis and see how bright the absorption lines are for the galaxy as a whole? The brightness of those lines compared to the general brightness of the entire spectrum would tell you the relative masses of the different types of stars.
Thanks for producing an interesting, no-nonsense channel with intelligent commentary. It's the right balance between the content and commentary, a rare thing on a TH-cam infested with people who think the whole point is not to captivate and interest people, but rather to impress us with how awesome they are. Gracias.
So far, I have seen a couple of reaction videos from you, on quite a vast variety of topics, and I was really intrigued by them all. You come up with interesting and clever comments very often and right on the spot. I have rarely seen such a logical smart mind in a young person. Hats off to you, young lady!
I have to say, I stumbled on your channel by complete accident, and I love it! Too few people in the world (or perhaps just in america) are TRULY curious, thoughtful, people who crave knowledge and perspective the way you seem to. I can tell just from your looks of thoughtfulness and genuine smirks and smiles that you LIVE for this stuff. Also, completely unrelated, girl I am SO JELLY of your smile. Keep ot up! Your reactions are highly underrated!
There is a theory that the earth is in quarantine. That a species landed here which was so evil that another species made the van allen belt to imprison them.
in fact, you are extremely correct. currently the human race is considered extremely underdeveloped. That is why this contact is being prepared gradually in our collective consciousness.
Iain Banks in is Culture Series has Earth being an untouched planet, that was used as a starting point when judging the successes of their own interventions of other planet's societies.
Been watching your vids for awhile... and subbed. I love your simple and thoughtful takes... great voice... chilled out and ready to learn and trade knowledge. I love that. You've won a new fan.
I enjoy your openness and the insightful comments you regularly make, which are quite often something I've never thought of. Your radiant smile is quite special too. Don't hate me for saying that, please.
It's not wrong to say that the smile is what attracted us to her. But it's the brain behind the smile that kept us. Tldr; the smile is beautiful, the intelligence is sexy.
@@Bbouy1HD "Bias" meaning favouring one thing over another? If that's your thrust, then, yes I prefer a beautiful smile to one that isn't. How is that weird?
This is one of my favourite things to think about, and you give such a genuinely insightful commentary on your videos. I know it’s gunna be a good one.
I believe we are either alone, or alone enough that we'll never know. I do believe there is a great filter ahead of us. I kinda just think kindness and keeping promises and all that kind of thing are what matters most. I don't think the discovery of life on another planet would change that. Usually it's something like a famine that changes that attitude in people. ...Or maybe things like famines only reveal that attitude to be untrue in some people. Enjoyed the double feature
A great book (series) regarding the Fermi Paradox: The Three Body Problem by Cixin Liu (in essence the idea of a "Dark forest" is introduced, where simillar to the video, type 2 and above civilizations exist, but are hidden to one another thanks to their stars being concieled in Dyson spheres. The books than go in to a what-if idea of large scale predation driven by fear.) Another nice piece of media that might interest you is the Dead Space video game trilogy, which introduces a version of the "Great Filter" mentioned in pt. 1.
One of my favorite Kurz videos is The Egg - A Short Story, It really makes you think outside the box and opens up a new perspective on things. Would love to see your reaction
Personally, I think the knowledge alone of alien life actually existence would give me so much motivation and inspiration. Currently, I find life unbelievably boring and monotonous and I don't have much motivation to do things that aren't absolutely necessary to stay alive. If actual evidence came out regarding outer-planetary life, I would be ecstatic and would try my darn hardest to find a way to interact with them myself.
I agree to a certain extent, we are definitely constructing our own emotion, spiritual and life smothering prisons daily with the advancement of technology.. But as far as finding out aliens exist, I think it would be catastrophic as people would fight to label them their specific Gods, Muslims, Christians and other religions in the initial stages would War to shape narratives as to who those beings were ..
@@GT-ry1cv Well I do believe there. However, the problem is that it isn't possible to make contact with them at the moment. I do study astrophysics and quantum mechanics, and while there are theories and future possibilities, all signs point at me not being able to experience such a life in my lifetime. If we had actual visual evidence of them, then that would me there is a current way to contact, and thus interact with them. As it stands, that doesn't exist and won't until long after I'm dead.
As far as I see it, the problem is with detection... any sufficiently advanced space-faring race isn't going to be broadcasting radio (or other spectrums of) waves out in all directions like a radio tower. Hell, we're probably not going to be using that form of mass communication much longer. True, we have been broadcasting radio waves for over 100 years, but that only gives a radius of 100 light years or so, which is the tiniest, tiniest fraction of the Milky Way... and even so, odds are that once you get past a light year or two, the waves would likely be so diluted that they would be indistinguishable from other sources. So the question is, how would we expect that any other life forms would know about us, and how would we possibly know about them?
For me, it comes down to time. I think there could be many civilizations like ours and maybe we are all just advancing in technology at the same rate. None of us would know about each other because our signals haven't had time to reach anyone yet
I loved your reaction and the fact that you choose this (amazing) video. I don't know if you'll ever see this comment, your channel is big and I like it! Anyway, I would reccomend you a react to "Tim Minchin - Thank you God", we can say it's pretty well done - a performance both comical and musical and takes some questions in a very (but "kinda")trully way.
To answer your question about if finding out would change you life in a meaningful way, I'm going to reference "Star Trek." On April 5, 2063, Zefram Cochrane made the first warp flight. A Vulcan survey ship was passing through our system at the time and picked up the warp trail (exhaust basically) and made first contact. When we learned that we weren't alone, all conflict on this planet ended within 100 years. Personally, I hope it happens something like this, and soon. We really need guidance.
Definite evidence of intelligent life on other planets would change my life in two ways and they are dependent on one condition: can we interact with them or not? If we can, learning about them would probably be one of the main ways I'd spend my time. If we cant and just know they are there, I'd be amused about the reactions of certain groups among my fellow humans for the forseable future. No comic, meme or stand-up comedy could beat people freaking out about that.
I’m paraphrasing the philosopher Wittgenstein: if lions could speak human language we would still not be able to understand them because their concepts would be too “alien” for us
Once they use standard candles or relativistic shift to determine a distance to a particular galaxy, cluster, or super cluster, they can estimate the number of stars pretty well using its proportions of spectral lines and overall luminosity.
Back in 1998, I mentioned the FParadox and life to my neighbor, a Ph.D. working on post-doc research at the Stanford University Particle Accelerator. He said there probably, not possibly, "an incredible amount of life out there, but at least two things keep us mere humans from coming across any by now: 1. the inconceivable distance between life forms (see info on the average distances between even neighboring solar systems, galaxies, and clusters), 2. given the distances, life forms with just a minimum IQ is not enough to seek out communication on both ends or life forms that care enough about other life forms out there---they may be in a similar situation to Earthlings, not trying hard enough to not annihilate each other with planet-killing weapons we have now. We would have to find a way to communicate using a method much faster than the speed of light and hope that at least one or both civilizations must translate language, which could itself take thousands of earth years, also."
The other videos about the scale of the Galaxy, and the reach of our Radio signals already answered this question. The distances are just so vast, that even with Signals traveling at speed of light, they have only reached a minuscule distance away from our solar system. Even if the signals reached another star system, there is no guarantee that that signal isn't disrupted by the energy that is dispersed from the other stars.
It seems that you might be interested to check out Isaac Arthur's channel. He goes into these kinds of existential topics to a much greater extent than Kurzgesagt. Much like them he collaborates with scientists in various fields to do deep dives into the big questions and their consequences. Take a look at his playlists to pick a topic that sparks your curiosity. They are on the longer side though (big ideas need more time to explore), so I am not sure if they would work for a reaction type video, but definitely should reach a broader audience in my humble opinion. His earlier videos might need captions to help with understanding his speech, but his community (rightly) persuaded him to keep being the voice on the videos instead of hiring a voice actor. If anyone has a recommendation for a good video of his to start the journey off with, please put them here. (I got to know him through the Fermi Paradox Compendium playlist, and was instantly hooked)
I am a little sad...Not only do I want to tell NO Protocol of how much she is beautiful. Of how much she inspires, and of course, I spoke of her incredible smile....All I want to do...Is wish her a Merry Christmas. I don't know why...the internet people call me Joe Joe D. Merry Christmas
This has the potential to be a great comment thread if someone who doesn't believe in space comments as long as it keeps positive. I had a friend who was a born carpenter/building trades fellow, with an encyclopedic knowledge of codes, fixtures, plumbing, electric etc. Anything to do with building a house, you name it, he was knowledgeable in it and managed to not be a know-it-all. He was also a high school dropout. He didn't believe me when I happened to mention that in the absence of atmosphere, a feather and a rock would hit the ground at the same time. I was stunned. I told him if he didn't believe me, to check that one of the experiments on the moon landing was to drop a hammer and a feather where they did indeed prove it to be true. We were in our 40's at the time so just because a person is very successful in life, it doesn't mean we're all on the same level when it comes to the physical world LOL I can assure you, he did believe in gravity though. 10:15 An interesting aside, in 2 Peter 3:6 (KJV) we are told of the "world that then was" being overflowed with water, perished." I don't think this is Noah's flood, as the world did not perish at that time. The ark would have had nothing to float on nor an olive leaf to bring back since olive trees don't grow overnight. One thing for sure: "world that then was" is a very interesting clause.
Science fiction books often tackle this topic. Revelation Space by Alastair Reynolds is my favorite, the author is a former astronomer and can explain real life science concepts in simple terms, while also having really cool worldbuilding and action.
Agreed! I'm working my way through the Revelation Space series right now and it's riveting. I actually stumbled across it because a pair of his stories were used in the animated Netflix anthology series, 'Love Death and Robots'. I was surprised when I learned that two of my favorite segments, 'Zima Blue' and 'Beyond the Aquilla Rift' were by the same author and quickly went to read the book they were based on (another anthology series).
@@bradleymay5350 I watched the show but didn't realize those episodes were based on his short stories, haven't read that collection yet. Gonna have to check it out.
The mass of the milky way can be estimated by how fast its spinning. My guess on why the number of stars vary is they first have to estimate how much of that mass is dark matter, then divide the rest by the average mass of the stars we've counted so far.
I think confirmed knowledge of intelligent life elsewhere in the universe would change everyone's life in some meaningful way. That knowledge would shift our perspective of humans and our place in existence, even as individuals. This is huge because perspective is what we use to determine how to move forward or why we do anything in the first place. So even though we still have to do human things like eat, sleep, and socialize, why you go to work -- if you decide to continue working at all -- or what you decide to study/do in life could definitely be altered simply by the knowledge that there is more out there than previously known.
I believe the great filter is comfort. When a civilization gets so advanced and life becomes easy, evolution stops and eventually civilizations tear themselves apart. I already see it starting for us.
@12:18 it might. We carry on our lives with many uncertainties; some factual knowledge of life outside our world to replace probability may have some impact on people's decisions. Possibly a flood of people interested in the prospect of exobiology, or even linguistics if communication is possible. Then again someone is just as likely to use fear of the slightly less unknown to manipulate people here at home. If it's at all possible to profit from the discovery someone is likely to find a way, or at least spend time looking for a way to exploit the discovery. Thankfully it's not an issue we have had to deal with yet, or discover for ourselves how humanity would react. Hopefully our first contact isn't with a civilization that see us as little more than pests.
If I found out for certain, without a doubt, that I was in a simulation, then I would do my best to break free of such a simulation. If you know there is no spoon, then what awaits is just the beginning.
When I was kid, I was concerned that we had sent broadcasts into space, but that we haven't heard a response. Then I learned that that even our earliest broadcasts have only reached out ~116 light years. Granted, that reaches ~14,000 stars, but maybe, if there is intelligent life on any of the planets in within that that ~116 light-year bubble, they are a few decades/centuries/millennia behind us. I do tend to believe that the "great filter" theory is the most probable reason for an apparent lack of a intelligent signals from the other side of the galaxy (>100K light years away), but as the Fermi Bubbles, discovered in 2010, might suggest, the galaxy is a dangerous place.
There were changes that came from humans discovering and interacting with other humans. Caffeine, gun powder, bathing techniques, germ prevention, birthing techniques, etc. So discovering other alien life forms might not affect the layperson in the interim, but it would surely have a trickle down effect
edit: book itself is by C.M. Kösemen but the video summarization is by Alt Shift X" Since we're on the topic of aliens, may I suggest the video summarization called "All Tomorrows: the future of humanity?" It's quite a long video (40 minutes) so I totally understand if its off-putting, but I feel like you'd definitely be interested in it! The cool catch is that it's humanity with strange speculative evolutionary pathways through billion year hurdles of rise and fall experiences, with bizarre alien results of what we've become.
It boils down to windows of opportunity. If they don't kill themselves, or their planet, every advanced civilization reaches a point of being able to listen for signals and explore nearby planets. Not only are the distances between habitable planets vast, but advanced civilizations must exist at the same points in time just to be able to recognize that someone else is out there. Due to the overwhelming odds against life forms like ours, I would guess that there may be a few civilizations per galaxy, and that none of them will ever meet..
I remember a movie. In the movie we, earth, were sending out signals to find other life. One scientist was trying to tell everyone to be careful, we might just find some.
7:30 - "We are all alone in this together." I think if we're the only intelligent life out there, we have a moral obligation to steward that spark. We need to get more baskets for our eggs, and once we're a little more spread out and sorted out, it might be worth investigating and seeding planets.
Newish to ur channel i love the content, really relaxing to chill and watch to pass and forget all the stress and life struggles. Only channel i have the bell on.
You can estimate a lot by only counting a small volume and extrapolate it to a bigger. The error rate is then not really high, with large numbers. The higher the number the lesser the error.
Just a question, what’s your academic training ? :) One funny paradox (which isn’t really one) comes from relativity theory, it’s called the Langevin’s twins problem. You should think about it before seeing directly the answer, it’s cool. About the reaction of knowing if life exists elsewhere, i guess it would be the fourth “Kränkungen der Menschheit” and then it would pathetically become a casual piece of information which, as every piece of information, people will forget or at least not care since it doesn’t affect their daily life after all, as you also said.
I just came across your channel, and I like the way you try to share your thoughts. As a matter of fact, in the process of finding information on a book I wrote concerning aliens. I had a thought experiment. This was after watching the voyager nearly a billion miles away turning around and taking a picture of Earth which was a dot in space. And the late Carl Sagan had to point it out. So I was wondering say aliens had some kind of superior technology to travel through interstellar space at some warp speed. First of all, with the vastness of space, you have to kind of no which direction you need to go, or target your radio beam. Another point is maybe aliens whose planets about eight billion years old for example could have visited our planet maybe nearly 4 billion years ago and thought nothing here let's move on. Then there is the idea that maybe aliens had already discovered other aliens on the other side of our galaxy. Then they might say Oh so there are other life forms all over the universe so why waste resources searching for another species. I actually wrote in my book's prologue how an alien species could try and find out about other aliens with a certain kind of technology.
One problem with predicting how many "habitable planets" there are, is that it is possible that there is something about our planet that is extremely uncommon, but because he don't have any real frame of reference we don't realize that it is rare. Also, eventually the universe will be a completely dark void absent of life and light, because stars burn out faster than they are created. So at the end of the day, that will be the greatest filter.
im sorry to write two comments back to back but on the idea of knowing that life exists elsewhere changing our lives in any meaningful way; I feel like the perspective it would give us would massively shift how we view ourselves and our relationship with the universe. the reason i feel that way is because despite most people have a real sense of feeling special, especially when it comes to certain religions. I honestly feel like the realization would make a lot of people have an existential crisis about their place in the universe. as for me i would simply be excited at the prospect of getting to see another intelligent species. If it became a new field of study i would go into it no questions asked
I'm pretty sure I remember reading that based on how old the universe is now, and how old it will be at the time of its inevitable heat death, of the planets that will be able to support intelligent life to evolve only 8% have currently been created. The universe is effectively still in its infancy. I just wish I could remember where I saw it.
You asked for recommends of this ilk, so I will suggest the channel "Rational Animations." Specifically the video, "Humanity was born way ahead of its time. The reason is grabby aliens." I'm pretty sure its narrated by Robert Miles who has his own youtube channel "Robert Miles" where he talks about AI safety research which might also be of interest.
I think one possibility not discussed much in the video is the possibilities of life/ civilizations beyond our perceivable understanding. Maybe this ties into civilization #3 somewhat but they could also not perceive us. Maybe they travel at the speed of light, or are infinitely small or big and we are all a part of another being. Or most likely some other way we can’t comprehend and have no idea about.
I really think as a species develops the idea of seeking out other civilisations lowers. Even our own technology has gotten smaller and smaller as it gets more powerful, I think advanced species might reach a stage where they stop looking outward and focus their technology on preserving their own habitat and keeping their civilization thriving. As they get smarter they could realise it just isn't viable to terraform other planets so use the tech to mine asteroid fields and other such things.
The star wars phrase, "A long time ago in a galaxy far far away", is very aptif we think that the earth has only been around for the last third of the universe's existence....
People who don't believe in the space and instead believe that we are in some sort of computer simulation or in a truman type show are the most ignorant and rather most hypothetical existential creatures 😅 As the narrator said in the end.. the universe is too beautiful to be not enjoyed by anyone. And imo.. we, as humans, on our planet Earth are one of the most complicated yet excellent bio-chemical organisms evolved to enjoy this universe by getting to know about it as much as possible. We will always be bounded with the laws of physics and will probably never able to reach to any other location in space where life can be found.. but this will never mean that there is no life out there in some other part of this universe... similarly bounded by the same physics laws as well. That's the beauty!! That's the thrill! We know we won't exist forever, and we know we will never see/meet anyone else other than us, yet we will keep evolving to find/learn more and more about the history, present and future of the universe
I recommend checking out the Remembrance of Earth's Past book series by Liu Cixin. It's an exploration of an theoretical answer to the Fermi Paradox: The Dark Forest Hypothesis.
In the movie Contact the main character says something interesting on this, "if there is nothing out there it is an awful waste of space". Even if other life forms exist their tech maybe so different any signals they might transmit on could be well out of our ability to pickup. Plus I heard theories that if there is other life perhaps they are exploring their neighborhood (as we are) and not ours.
That's so true, as humans we rely solely on our 5 senses, that other alien life-forms may not even have, it's impossible to predict or even comprehend other senses. We can never experience the world the same way as some birds who can sense magnetic fields.
@@MasterIceyy Super observation, I totally agree with that analogy. This video does make you think which is what she does very well. Thanks for the cool reply.
Literary recommendations: "If The Universe Is Teeming With Aliens...WHERE IS EVERYBODY? Fifty solutions to the Fermi Paradox and the problem of extraterrestrial life" by Steven Webb. It is great fun to read, and he does eventually give his opinion to the question. Liu Cixin's 'Remembrance of Earth's Past' trilogy consisting of "The Three Body Problem", "The Dark Forest", and "Death's End". Suppose technologically advanced civilizations become aware of your existence and your location? Of course, human hubris doesn't help
It is frequently mentioned how many planets could potentially support life, as though this is the only pre-requisite. There are many other factors to consider. The gas giants in our solar system protect this planet from most of the meteors and other large debris that would hit us, because their gravitational pull is so much larger than ours. Given that the incredibly rare occasions that our planet is hit by larger meteors are considered mass extinction events, there would be very little opportunity for life to begin if this was a more regular occurance. Our planet has existed for 4.6 billion years and yet it took almost one billion years until the earliest forms of life started. More advanced forms of life have only been around for about half a billion years and whilst humans have existed for around two million years very little advancement happened until the last ten thousand years. These advances only occured as the result of a relatively stable climate, which allowed settling and eventually farming. Now consider that that major technological advances have only really occured since the industrial revolution in the past two hundred years, which is a microscopic window of time. If we assume then that there is a very small chance for life on these myriad planets that could potentially support life. There is a slightly smaller chance for advanced, mulit-cellular life, but a much smaller chance for a lifeform with the potential to become highly intelligent and a much smaller chance still that that life will have the opportunity to develop further. Then we get to that incredibly small window of two hundred years that had a tiny chance of occuring, before we start making noise that the universe might hear. So there is the tiniest chance that other life forms have been able to make similar noise and an even smaller chance that they would be making that noise at anywhere near the same time as us. Then if we think ahead, how long will humanity survive. Will it just be this incredibly short two hundred year blip of technological advancement or do we have a long future ahead of us. If any similar technologically advanced life has only lasted two hundred years, then we would have virtually no chance of it being at a time point that would still leave any trace of it's existance. If it lasted any longer, how advanced would it become. Certainly within a very short time it would advance far enough to be able to ensure we would not be able to trace it. Think what we have achieved in the past two hundred years, now imagine another two years, another two thousand years, twenty thousand years, is there a limit to what could be achieved and how invisible we could make ourselved to any less avanced species. Now consider the expansion of the universe. As fast as any technology can advance all of the planets and systems in the universe are moving further apart from each other, making the chances of reaching out to other planets that much smaller.
Interesting thing to think about in regards to the likely hood of life. The conditions for life to start existed here on earth. however given that we have only every seen life start here once. every form of life we have ever found shares DNA in common witch each other. so even under the right conditions it only happened once. that we know of anyway. its also posable that this version of life was just so much more successful that it wiped out the other version so fast theres no record of them left anymore.
Thanks for the great video!! A.I. and Crisper technology might be great filters in our future. I wouldn't be surprised if simple life is super common. Planets that are conducive to evolution and habitable to complex life might be insanely rare. Things like: having a undersized black hole for our galaxy, not being in a dangerous part of the galaxy, having a "calm" star, a nice sized moon with decent tidal forces, an abundance of a lot of different elements, a thin mantel with an active tectonic crust, a molten core that creates a magnetosphere to protect an atmosphere and a liquid ocean, as well as many unknown factors helped earth out. Having all the correct pieces fall together might be a difficult dice roll to achieve. Early life started 3.5+ billion year ago, leading to the "boring billions", complex life started 800+ million years ago, on a slightly less habitable world they might still be in their boring billions or their star could die out before complex life even takes off. Maybe there is complex life our galaxy but it's near geothermal vents and trapped under miles of ice. Alien civilizations might be almost unique to each galaxy (if a galaxy is capable of life and not some hyperactive galaxy that is sterilizing life before it can begin), but we have one example of it happing in our galaxy, so it's not impossible.
The first filter they mentioned, the difficulty of life spontaneously forming, seems one of the more plausible to me. The complex folded proteins that could make other proteins repeat the same complex folds has an incredibly small probability of occurring randomly. From current understanding of biology, there has not been enough time in the visible universe for that to have occurred once over the trillions upon trillions of planets out there and the billions of years the universe has existed…clearly it has happened or we wouldn’t be here but it gets you thinking. Of course, we might figure out that there’s a mechanism that makes those complex proteins inevitable…but we’ve yet to replicate that process, or seen evidence of it not being a fluke occurrence.
You asked how would the knowledge that we're not alone would impact us... personally I have been raised with the notion that it's mathematically impossible that we're alone in the universe, so it's just another day for me.
the thought that we may one day become the type 3 species who keep the "flame of life alive" makes me feel a sense of duty to mankind as a whole. with how "crazy" the world is today i feel like we need more people who will stand up against everything and unite us all under the banner of something grandiose like this. idk i feel like it could get our minds off of the silly stuff we argue about
On the Question of how many stars are there in the Milkyway. The reason for the different answers is we get these answers by using very rigorous guesstimation. No one's actually counted all of them, we know we can't see many of them. Add onto that, brown dwarf's are they stars? So there's a definition issue there on where the line is drawn and since they are hard to see we have little information on them. So somewhere between 100-400 Billion is probably in the right ball park.
Another great video from a very intelligent lady. You're a breath of fresh air on platform full of noise. You should d listen to professor brian cox on "we are all made of stars"
There was a British scifi comedy called Red Dwarf. It was about the very last human in the universe. And there was no life other than humans in the galaxy. It was more comedy than scifi, but it did occasionally bring up actual hard science, too.
It is also possible that we are just unable to see other life forms, given that we are still only capable of perceiving a relatively small spectrum of light especially at great distances, even at close distances we are unable to see the very air we breathe. Also there have been recordings of events in history that depict humans being unable to see things directly in front of them that are beyond their understanding, if I'm not mistaken it was either Alaskan Eskimos or native Americans and something to do with ships or photographs... and maybe, they're already here. So, I think that the impact of the knowledge of extraterrestrial life would be largely dependent on their proximity to us, and or perceived potential influence in that regard. It would likely inspire a great degree of intrigue or fear.
I don't think either that the discovery of other life forms on other planets would change our day to day life, but I think it would certainly change our future in a sense that it would lead to a shift in the way we see ourselves, a bit (and probably on a much larger scale) like when Occident rediscovered that Earth wasn't the center of the Solar system. Just this fact would, in my opinion, operate a notable change of perspective and priorities in many subjects, be they scientific, social, artistic, economic, etc. For now, we are so incredibly egocentrics, and narcissistic than we keep acting like if all things that exist is there just for us, self-appointed ultimate form of life (funny how most religious system still emphasize that fact while preaching humility... what a paradox!).
In a nutshell: Our universe is a construct of our combined will, narrowing our perceptions in exchange for heightened clarity between us. There is only one person, and it's all of us, like facets of a gem. This is Plato's Allegory of the Cave, and his World of Forms. I, personally, think he described it really poorly, but he did sketch the rough outlines, thousands of years ago. It isn't that this world doesn't exist, the material and temporal are transitory, but the relationships and interactions among all things are actually forms of communication between ourselves. The only truly "real" things are values, in all sorts of aspects. If there are aliens on other planets, then they, too, must inevitably be part of the great Self. Else they are extra-universal intruders born from a different construct.
I think that if we found that there is life other than on Earth, it would not have an immediate impact on our lives, but it would have an immediate impact on our way of thinking and our technological development. So eventually it would impact our lives.
When they said you could live around a red dwarf star inside of a simulation without feeling "bored or sad" i dont think he actually ment those specific feelings. It's like in VR Chat. You can be bored and sad there but that would honestly be as close to perfect as i could imagine. Think about it. You could spend your entire day talking to people and socializing. You can also play games with them or work on really advanced concepts like quantum mechanics without ever having to starve or suffer. The main idea is that you can create a world in which you feel as compfortable as possible. And if you don't like it you can change something. I am sure that there would still be existential dread and you would have to find some sort of meaning you could hold onto which would be hard to do in this context but it would definately erase alot of the problems we are facing now.
I think the largest change in peoples lives would be the realisation that we are more similar than we currently think. there would be much less motivation to kill for religious or political beliefs if we knew our petty actions pale in comparison to the impending change that contact would embody. for example, if you were in a petty squable with your neighbours over noise or something minor, then the city council tells you theyre demolishing your neighbourhood to build a road, would you not band together with those very same neighbours to save your homes in collective action against a more powerful threat? same for states/provinces/areas vs national/federal government, same as nations vs foreign invasions, same for humanity vs alien civilisations imo.
The bound on stars are all over the place because of small red-dwarfs which are hard to count, because they are dim. Those don't really matter for life, because it's not likely red-dwarfs of any kind will host life-planets, because their habitable zone is too close to the star, so the solar flares strip the planet of atmosphere (red dwarfs are active).
I don't know what the first message by Morse code was but, when the UCLA first tested communication over the internet to Stanford (via the ARPANET), they tried to send the word LOGIN. However the system crashed after LO. So when they rebooted and tried again, they sent the full word LOGIN, but technically the first text ever transmitted over the internet was LOL
"This one didn't give me as much of an existential crisis as I'd hoped." Nerd points awarded for that line! Great reaction as alwyas.
alien existence would probably unite all humans since we will finally have competition or a common enemy/threat. No bond is stronger than hate.

Kurzgesagt's content, especially their more recent stuff, is absolutely amazing. They have plenty of videos that WILL give you that existential crisis feeling.

Right, even the most "foreign" human shares so much of a common frame of reference that it is actually possible for people to learn new languages through immersion. We all are wired to be able to learn language, we see in largely the same spectra, can hear largely the same frequency ranges, and so on.
In spite of that, small differences in cultures and values have caused massive conflicts. How would we even establish a handshake, so to speak, with an alien species? As it stands we'd likely have to use some sort of statistical analysis on communications received (if we're lucky enough to be able to perceive them at all) and for that we'd be depending on AI...
One of my most favorite Kurzgesagt videos is their animation of the short story "The Egg" by Andy Wier, definitely caused some existential reflection on my entire life.
The concept of the story both changed and reaffirmed my worldview, and I feel the philosophy of the story is a very beneficial mindset to take on.
One way they estimate galactic size is by their gravitational effects. We may better know the masses involved than in the number of objects that mass is divided into.
Thank God for minds and words seek Jesus
And not just the gravity from visible matter you have to counter in the effects of dark matter to get an accurate reading for the gravitational effects of a galaxy too.
Could you do a high resolution spectral analysis and see how bright the absorption lines are for the galaxy as a whole? The brightness of those lines compared to the general brightness of the entire spectrum would tell you the relative masses of the different types of stars.
Thanks for producing an interesting, no-nonsense channel with intelligent commentary.
It's the right balance between the content and commentary, a rare thing on a TH-cam infested with people who think the whole point is not to captivate and interest people, but rather to impress us with how awesome they are.
Gracias.
So far, I have seen a couple of reaction videos from you, on quite a vast variety of topics, and I was really intrigued by them all. You come up with interesting and clever comments very often and right on the spot. I have rarely seen such a logical smart mind in a young person. Hats off to you, young lady!
I have to say, I stumbled on your channel by complete accident, and I love it! Too few people in the world (or perhaps just in america) are TRULY curious, thoughtful, people who crave knowledge and perspective the way you seem to. I can tell just from your looks of thoughtfulness and genuine smirks and smiles that you LIVE for this stuff. Also, completely unrelated, girl I am SO JELLY of your smile. Keep ot up! Your reactions are highly underrated!
I’m still convinced the galaxy is using Earth as an insane asylum.
There is a theory that the earth is in quarantine. That a species landed here which was so evil that another species made the van allen belt to imprison them.
A Galactic zoo. All different types of species of organisms just thrown onto the one planet.
in fact, you are extremely correct. currently the human race is considered extremely underdeveloped. That is why this contact is being prepared gradually in our collective consciousness.
I'm here...so yeah....and we are running the asylum....Peace!
Iain Banks in is Culture Series has Earth being an untouched planet, that was used as a starting point when judging the successes of their own interventions of other planet's societies.
Been watching your vids for awhile... and subbed. I love your simple and thoughtful takes... great voice... chilled out and ready to learn and trade knowledge. I love that. You've won a new fan.
I enjoy your openness and the insightful comments you regularly make, which are quite often something I've never thought of. Your radiant smile is quite special too. Don't hate me for saying that, please.
It's not wrong to say that the smile is what attracted us to her. But it's the brain behind the smile that kept us.
Tldr; the smile is beautiful, the intelligence is sexy.

@@Bbouy1HD "Bias" meaning favouring one thing over another? If that's your thrust, then, yes I prefer a beautiful smile to one that isn't. How is that weird?
This is one of my favourite things to think about, and you give such a genuinely insightful commentary on your videos. I know it’s gunna be a good one.
Can you please do a video/reaction on the "Double Slit Experiment" 🙏🏼
I love that you are doing reactions to kurzgesagt. One of my favorite channels of all time for sure! I enjoy watching these with you 😁
I believe we are either alone, or alone enough that we'll never know. I do believe there is a great filter ahead of us. I kinda just think kindness and keeping promises and all that kind of thing are what matters most. I don't think the discovery of life on another planet would change that. Usually it's something like a famine that changes that attitude in people. ...Or maybe things like famines only reveal that attitude to be untrue in some people. Enjoyed the double feature
A great book (series) regarding the Fermi Paradox: The Three Body Problem by Cixin Liu
(in essence the idea of a "Dark forest" is introduced, where simillar to the video, type 2 and above civilizations exist, but are hidden to one another thanks to their stars being concieled in Dyson spheres. The books than go in to a what-if idea of large scale predation driven by fear.)
Another nice piece of media that might interest you is the Dead Space video game trilogy, which introduces a version of the "Great Filter" mentioned in pt. 1.
Was just about to write the same thing ;)
Thanks!
Thank you too (:
I appreciate your videos. It is comforting to see others thinking and discussing these subjects intelligently
i love your mindset and personality, you're very open-minded which is so nice. keep it up! 💗
One of my favorite Kurz videos is The Egg - A Short Story, It really makes you think outside the box and opens up a new perspective on things. Would love to see your reaction
I love how varied your content is.. got here from Al Murray and always interesting and intelligent reaction.
Personally, I think the knowledge alone of alien life actually existence would give me so much motivation and inspiration. Currently, I find life unbelievably boring and monotonous and I don't have much motivation to do things that aren't absolutely necessary to stay alive. If actual evidence came out regarding outer-planetary life, I would be ecstatic and would try my darn hardest to find a way to interact with them myself.
How curious, fair enough!
I agree to a certain extent, we are definitely constructing our own emotion, spiritual and life smothering prisons daily with the advancement of technology..
But as far as finding out aliens exist, I think it would be catastrophic as people would fight to label them their specific Gods, Muslims, Christians and other religions in the initial stages would War to shape narratives as to who those beings were ..
So why don't you just believe that there is life out there and change your life?
@@GT-ry1cv Well I do believe there. However, the problem is that it isn't possible to make contact with them at the moment. I do study astrophysics and quantum mechanics, and while there are theories and future possibilities, all signs point at me not being able to experience such a life in my lifetime. If we had actual visual evidence of them, then that would me there is a current way to contact, and thus interact with them. As it stands, that doesn't exist and won't until long after I'm dead.
As far as I see it, the problem is with detection... any sufficiently advanced space-faring race isn't going to be broadcasting radio (or other spectrums of) waves out in all directions like a radio tower. Hell, we're probably not going to be using that form of mass communication much longer. True, we have been broadcasting radio waves for over 100 years, but that only gives a radius of 100 light years or so, which is the tiniest, tiniest fraction of the Milky Way... and even so, odds are that once you get past a light year or two, the waves would likely be so diluted that they would be indistinguishable from other sources.
So the question is, how would we expect that any other life forms would know about us, and how would we possibly know about them?
I think Brian cox said, one form of intelligent life in each galaxy. also, universal by Brian and Jeff Forshaw is a good read.
For me, it comes down to time. I think there could be many civilizations like ours and maybe we are all just advancing in technology at the same rate. None of us would know about each other because our signals haven't had time to reach anyone yet
A singularity (life in earth) trying to find another singularity
i am loving this channel! keep up the great posts please :) big love to all people :)
I loved your reaction and the fact that you choose this (amazing) video. I don't know if you'll ever see this comment, your channel is big and I like it! Anyway, I would reccomend you a react to "Tim Minchin - Thank you God", we can say it's pretty well done - a performance both comical and musical and takes some questions in a very (but "kinda")trully way.
To answer your question about if finding out would change you life in a meaningful way, I'm going to reference "Star Trek." On April 5, 2063, Zefram Cochrane made the first warp flight. A Vulcan survey ship was passing through our system at the time and picked up the warp trail (exhaust basically) and made first contact. When we learned that we weren't alone, all conflict on this planet ended within 100 years. Personally, I hope it happens something like this, and soon. We really need guidance.
Definite evidence of intelligent life on other planets would change my life in two ways and they are dependent on one condition: can we interact with them or not? If we can, learning about them would probably be one of the main ways I'd spend my time. If we cant and just know they are there, I'd be amused about the reactions of certain groups among my fellow humans for the forseable future. No comic, meme or stand-up comedy could beat people freaking out about that.
"this wasn't the existential crisis I was hoping it would be."
How are you this damn awesome?
One the best react channels on youtube
Nice reaction, keep it up with the content
I’m paraphrasing the philosopher Wittgenstein: if lions could speak human language we would still not be able to understand them because their concepts would be too “alien” for us
“This one didn’t give me as much of an existential crisis as I’d hoped” 😂
Once they use standard candles or relativistic shift to determine a distance to a particular galaxy, cluster, or super cluster, they can estimate the number of stars pretty well using its proportions of spectral lines and overall luminosity.
Your young, at 65, I could imagine a life without grief or pain. Sometimes I can't tell which is worse, living or not.
As boredom and sadness are near daily occurrences for me, i'd be quite pleased with a life without them.
Back in 1998, I mentioned the FParadox and life to my neighbor, a Ph.D. working on post-doc research at the Stanford University Particle Accelerator. He said there probably, not possibly, "an incredible amount of life out there, but at least two things keep us mere humans from coming across any by now: 1. the inconceivable distance between life forms (see info on the average distances between even neighboring solar systems, galaxies, and clusters), 2. given the distances, life forms with just a minimum IQ is not enough to seek out communication on both ends or life forms that care enough about other life forms out there---they may be in a similar situation to Earthlings, not trying hard enough to not annihilate each other with planet-killing weapons we have now. We would have to find a way to communicate using a method much faster than the speed of light and hope that at least one or both civilizations must translate language, which could itself take thousands of earth years, also."
15:02
Contrast is what gives life definition.
If you're happy all of the time, how would you even know?
The other videos about the scale of the Galaxy, and the reach of our Radio signals already answered this question. The distances are just so vast, that even with Signals traveling at speed of light, they have only reached a minuscule distance away from our solar system. Even if the signals reached another star system, there is no guarantee that that signal isn't disrupted by the energy that is dispersed from the other stars.
It seems that you might be interested to check out Isaac Arthur's channel. He goes into these kinds of existential topics to a much greater extent than Kurzgesagt. Much like them he collaborates with scientists in various fields to do deep dives into the big questions and their consequences. Take a look at his playlists to pick a topic that sparks your curiosity. They are on the longer side though (big ideas need more time to explore), so I am not sure if they would work for a reaction type video, but definitely should reach a broader audience in my humble opinion.
His earlier videos might need captions to help with understanding his speech, but his community (rightly) persuaded him to keep being the voice on the videos instead of hiring a voice actor.
If anyone has a recommendation for a good video of his to start the journey off with, please put them here. (I got to know him through the Fermi Paradox Compendium playlist, and was instantly hooked)
"That didn't give me the existential crises I was hoping for"... lol, that's awesome
I am a little sad...Not only do I want to tell NO Protocol of how much she is beautiful. Of how much she inspires, and of course, I spoke of her incredible smile....All I want to do...Is wish her a Merry Christmas. I don't know why...the internet people call me Joe Joe D. Merry Christmas
This has the potential to be a great comment thread if someone who doesn't believe in space comments as long as it keeps positive. I had a friend who was a born carpenter/building trades fellow, with an encyclopedic knowledge of codes, fixtures, plumbing, electric etc. Anything to do with building a house, you name it, he was knowledgeable in it and managed to not be a know-it-all. He was also a high school dropout. He didn't believe me when I happened to mention that in the absence of atmosphere, a feather and a rock would hit the ground at the same time. I was stunned. I told him if he didn't believe me, to check that one of the experiments on the moon landing was to drop a hammer and a feather where they did indeed prove it to be true. We were in our 40's at the time so just because a person is very successful in life, it doesn't mean we're all on the same level when it comes to the physical world LOL I can assure you, he did believe in gravity though.
10:15 An interesting aside, in 2 Peter 3:6 (KJV) we are told of the "world that then was" being overflowed with water, perished." I don't think this is Noah's flood, as the world did not perish at that time. The ark would have had nothing to float on nor an olive leaf to bring back since olive trees don't grow overnight. One thing for sure: "world that then was" is a very interesting clause.
Science fiction books often tackle this topic. Revelation Space by Alastair Reynolds is my favorite, the author is a former astronomer and can explain real life science concepts in simple terms, while also having really cool worldbuilding and action.
Agreed! I'm working my way through the Revelation Space series right now and it's riveting. I actually stumbled across it because a pair of his stories were used in the animated Netflix anthology series, 'Love Death and Robots'. I was surprised when I learned that two of my favorite segments, 'Zima Blue' and 'Beyond the Aquilla Rift' were by the same author and quickly went to read the book they were based on (another anthology series).
@@bradleymay5350 I watched the show but didn't realize those episodes were based on his short stories, haven't read that collection yet. Gonna have to check it out.
The mass of the milky way can be estimated by how fast its spinning.
My guess on why the number of stars vary is they first have to estimate how much of that mass is dark matter, then divide the rest by the average mass of the stars we've counted so far.
I think confirmed knowledge of intelligent life elsewhere in the universe would change everyone's life in some meaningful way. That knowledge would shift our perspective of humans and our place in existence, even as individuals. This is huge because perspective is what we use to determine how to move forward or why we do anything in the first place. So even though we still have to do human things like eat, sleep, and socialize, why you go to work -- if you decide to continue working at all -- or what you decide to study/do in life could definitely be altered simply by the knowledge that there is more out there than previously known.
I believe the great filter is comfort. When a civilization gets so advanced and life becomes easy, evolution stops and eventually civilizations tear themselves apart. I already see it starting for us.
@12:18 it might. We carry on our lives with many uncertainties; some factual knowledge of life outside our world to replace probability may have some impact on people's decisions. Possibly a flood of people interested in the prospect of exobiology, or even linguistics if communication is possible. Then again someone is just as likely to use fear of the slightly less unknown to manipulate people here at home. If it's at all possible to profit from the discovery someone is likely to find a way, or at least spend time looking for a way to exploit the discovery. Thankfully it's not an issue we have had to deal with yet, or discover for ourselves how humanity would react. Hopefully our first contact isn't with a civilization that see us as little more than pests.
If I found out for certain, without a doubt, that I was in a simulation, then I would do my best to break free of such a simulation. If you know there is no spoon, then what awaits is just the beginning.
When I was kid, I was concerned that we had sent broadcasts into space, but that we haven't heard a response. Then I learned that that even our earliest broadcasts have only reached out ~116 light years. Granted, that reaches ~14,000 stars, but maybe, if there is intelligent life on any of the planets in within that that ~116 light-year bubble, they are a few decades/centuries/millennia behind us.
I do tend to believe that the "great filter" theory is the most probable reason for an apparent lack of a intelligent signals from the other side of the galaxy (>100K light years away), but as the Fermi Bubbles, discovered in 2010, might suggest, the galaxy is a dangerous place.
There were changes that came from humans discovering and interacting with other humans. Caffeine, gun powder, bathing techniques, germ prevention, birthing techniques, etc. So discovering other alien life forms might not affect the layperson in the interim, but it would surely have a trickle down effect
edit: book itself is by C.M. Kösemen but the video summarization is by Alt Shift X"
Since we're on the topic of aliens, may I suggest the video summarization called "All Tomorrows: the future of humanity?" It's quite a long video (40 minutes) so I totally understand if its off-putting, but I feel like you'd definitely be interested in it! The cool catch is that it's humanity with strange speculative evolutionary pathways through billion year hurdles of rise and fall experiences, with bizarre alien results of what we've become.
It boils down to windows of opportunity. If they don't kill themselves, or their planet, every advanced civilization reaches a point of being able to listen for signals and explore nearby planets. Not only are the distances between habitable planets vast, but advanced civilizations must exist at the same points in time just to be able to recognize that someone else is out there. Due to the overwhelming odds against life forms like ours, I would guess that there may be a few civilizations per galaxy, and that none of them will ever meet..
I remember a movie. In the movie we, earth, were sending out signals to find other life. One scientist was trying to tell everyone to be careful, we might just find some.
7:30 - "We are all alone in this together." I think if we're the only intelligent life out there, we have a moral obligation to steward that spark. We need to get more baskets for our eggs, and once we're a little more spread out and sorted out, it might be worth investigating and seeding planets.
Newish to ur channel i love the content, really relaxing to chill and watch to pass and forget all the stress and life struggles. Only channel i have the bell on.
This compliment isn’t lost on me. I’m just chilling too. Thanks for watching (:
You can estimate a lot by only counting a small volume and extrapolate it to a bigger. The error rate is then not really high, with large numbers. The higher the number the lesser the error.
Just a question, what’s your academic training ? :)
One funny paradox (which isn’t really one) comes from relativity theory, it’s called the Langevin’s twins problem. You should think about it before seeing directly the answer, it’s cool.
About the reaction of knowing if life exists elsewhere, i guess it would be the fourth “Kränkungen der Menschheit” and then it would pathetically become a casual piece of information which, as every piece of information, people will forget or at least not care since it doesn’t affect their daily life after all, as you also said.
I just came across your channel, and I like the way you try to share your thoughts. As a matter of fact, in the process of finding information on a book I wrote concerning aliens. I had a thought experiment. This was after watching the voyager nearly a billion miles away turning around and taking a picture of Earth which was a dot in space. And the late Carl Sagan had to point it out.
So I was wondering say aliens had some kind of superior technology to travel through interstellar space at some warp speed.
First of all, with the vastness of space, you have to kind of no which direction you need to go, or target your radio beam. Another point is maybe aliens whose planets about eight billion years old for example could have visited our planet maybe nearly 4 billion years ago and thought nothing here let's move on. Then there is the idea that maybe aliens had already discovered other aliens on the other side of our galaxy. Then they might say Oh so there are other life forms all over the universe so why waste resources searching for another species. I actually wrote in my book's prologue how an alien species could try and find out about other aliens with a certain kind of technology.
One problem with predicting how many "habitable planets" there are, is that it is possible that there is something about our planet that is extremely uncommon, but because he don't have any real frame of reference we don't realize that it is rare.
Also, eventually the universe will be a completely dark void absent of life and light, because stars burn out faster than they are created. So at the end of the day, that will be the greatest filter.
im sorry to write two comments back to back but on the idea of knowing that life exists elsewhere changing our lives in any meaningful way; I feel like the perspective it would give us would massively shift how we view ourselves and our relationship with the universe.
the reason i feel that way is because despite most people have a real sense of feeling special, especially when it comes to certain religions. I honestly feel like the realization would make a lot of people have an existential crisis about their place in the universe.
as for me i would simply be excited at the prospect of getting to see another intelligent species. If it became a new field of study i would go into it no questions asked
I'm pretty sure I remember reading that based on how old the universe is now, and how old it will be at the time of its inevitable heat death, of the planets that will be able to support intelligent life to evolve only 8% have currently been created.
The universe is effectively still in its infancy.
I just wish I could remember where I saw it.
You asked for recommends of this ilk, so I will suggest the channel "Rational Animations." Specifically the video, "Humanity was born way ahead of its time. The reason is grabby aliens."
I'm pretty sure its narrated by Robert Miles who has his own youtube channel "Robert Miles" where he talks about AI safety research which might also be of interest.
I think one possibility not discussed much in the video is the possibilities of life/ civilizations beyond our perceivable understanding. Maybe this ties into civilization #3 somewhat but they could also not perceive us. Maybe they travel at the speed of light, or are infinitely small or big and we are all a part of another being. Or most likely some other way we can’t comprehend and have no idea about.
I really think as a species develops the idea of seeking out other civilisations lowers. Even our own technology has gotten smaller and smaller as it gets more powerful, I think advanced species might reach a stage where they stop looking outward and focus their technology on preserving their own habitat and keeping their civilization thriving. As they get smarter they could realise it just isn't viable to terraform other planets so use the tech to mine asteroid fields and other such things.
The star wars phrase, "A long time ago in a galaxy far far away", is very aptif we think that the earth has only been around for the last third of the universe's existence....
People who don't believe in the space and instead believe that we are in some sort of computer simulation or in a truman type show are the most ignorant and rather most hypothetical existential creatures 😅
As the narrator said in the end.. the universe is too beautiful to be not enjoyed by anyone. And imo.. we, as humans, on our planet Earth are one of the most complicated yet excellent bio-chemical organisms evolved to enjoy this universe by getting to know about it as much as possible.
We will always be bounded with the laws of physics and will probably never able to reach to any other location in space where life can be found.. but this will never mean that there is no life out there in some other part of this universe... similarly bounded by the same physics laws as well.
That's the beauty!! That's the thrill!
We know we won't exist forever, and we know we will never see/meet anyone else other than us, yet we will keep evolving to find/learn more and more about the history, present and future of the universe
I recommend checking out the Remembrance of Earth's Past book series by Liu Cixin. It's an exploration of an theoretical answer to the Fermi Paradox: The Dark Forest Hypothesis.
In the movie Contact the main character says something interesting on this, "if there is nothing out there it is an awful waste of space". Even if other life forms exist their tech maybe so different any signals they might transmit on could be well out of our ability to pickup. Plus I heard theories that if there is other life perhaps they are exploring their neighborhood (as we are) and not ours.
That's so true, as humans we rely solely on our 5 senses, that other alien life-forms may not even have, it's impossible to predict or even comprehend other senses.
We can never experience the world the same way as some birds who can sense magnetic fields.
@@MasterIceyy Super observation, I totally agree with that analogy. This video does make you think which is what she does very well. Thanks for the cool reply.

"If The Universe Is Teeming With Aliens...WHERE IS EVERYBODY? Fifty solutions to the Fermi Paradox and the problem of extraterrestrial life" by Steven Webb. It is great fun to read, and he does eventually give his opinion to the question.

15:28 Is that Super Kame Dende???
It is frequently mentioned how many planets could potentially support life, as though this is the only pre-requisite. There are many other factors to consider. The gas giants in our solar system protect this planet from most of the meteors and other large debris that would hit us, because their gravitational pull is so much larger than ours. Given that the incredibly rare occasions that our planet is hit by larger meteors are considered mass extinction events, there would be very little opportunity for life to begin if this was a more regular occurance. Our planet has existed for 4.6 billion years and yet it took almost one billion years until the earliest forms of life started. More advanced forms of life have only been around for about half a billion years and whilst humans have existed for around two million years very little advancement happened until the last ten thousand years. These advances only occured as the result of a relatively stable climate, which allowed settling and eventually farming. Now consider that that major technological advances have only really occured since the industrial revolution in the past two hundred years, which is a microscopic window of time.
If we assume then that there is a very small chance for life on these myriad planets that could potentially support life. There is a slightly smaller chance for advanced, mulit-cellular life, but a much smaller chance for a lifeform with the potential to become highly intelligent and a much smaller chance still that that life will have the opportunity to develop further. Then we get to that incredibly small window of two hundred years that had a tiny chance of occuring, before we start making noise that the universe might hear. So there is the tiniest chance that other life forms have been able to make similar noise and an even smaller chance that they would be making that noise at anywhere near the same time as us.
Then if we think ahead, how long will humanity survive. Will it just be this incredibly short two hundred year blip of technological advancement or do we have a long future ahead of us. If any similar technologically advanced life has only lasted two hundred years, then we would have virtually no chance of it being at a time point that would still leave any trace of it's existance. If it lasted any longer, how advanced would it become. Certainly within a very short time it would advance far enough to be able to ensure we would not be able to trace it. Think what we have achieved in the past two hundred years, now imagine another two years, another two thousand years, twenty thousand years, is there a limit to what could be achieved and how invisible we could make ourselved to any less avanced species.
Now consider the expansion of the universe. As fast as any technology can advance all of the planets and systems in the universe are moving further apart from each other, making the chances of reaching out to other planets that much smaller.
Interesting thing to think about in regards to the likely hood of life. The conditions for life to start existed here on earth. however given that we have only every seen life start here once. every form of life we have ever found shares DNA in common witch each other. so even under the right conditions it only happened once. that we know of anyway. its also posable that this version of life was just so much more successful that it wiped out the other version so fast theres no record of them left anymore.
Thanks for the great video!! A.I. and Crisper technology might be great filters in our future.
I wouldn't be surprised if simple life is super common. Planets that are conducive to evolution and habitable to complex life might be insanely rare. Things like: having a undersized black hole for our galaxy, not being in a dangerous part of the galaxy, having a "calm" star, a nice sized moon with decent tidal forces, an abundance of a lot of different elements, a thin mantel with an active tectonic crust, a molten core that creates a magnetosphere to protect an atmosphere and a liquid ocean, as well as many unknown factors helped earth out. Having all the correct pieces fall together might be a difficult dice roll to achieve.
Early life started 3.5+ billion year ago, leading to the "boring billions", complex life started 800+ million years ago, on a slightly less habitable world they might still be in their boring billions or their star could die out before complex life even takes off. Maybe there is complex life our galaxy but it's near geothermal vents and trapped under miles of ice. Alien civilizations might be almost unique to each galaxy (if a galaxy is capable of life and not some hyperactive galaxy that is sterilizing life before it can begin), but we have one example of it happing in our galaxy, so it's not impossible.
The first filter they mentioned, the difficulty of life spontaneously forming, seems one of the more plausible to me. The complex folded proteins that could make other proteins repeat the same complex folds has an incredibly small probability of occurring randomly. From current understanding of biology, there has not been enough time in the visible universe for that to have occurred once over the trillions upon trillions of planets out there and the billions of years the universe has existed…clearly it has happened or we wouldn’t be here but it gets you thinking. Of course, we might figure out that there’s a mechanism that makes those complex proteins inevitable…but we’ve yet to replicate that process, or seen evidence of it not being a fluke occurrence.
Maybe I've just missed it, but you should do a video about the Drake Equation which has huge implications for the Fermi Paradox.
Best intellectual reactor on youtube 😊
You asked how would the knowledge that we're not alone would impact us... personally I have been raised with the notion that it's mathematically impossible that we're alone in the universe, so it's just another day for me.
the thought that we may one day become the type 3 species who keep the "flame of life alive" makes me feel a sense of duty to mankind as a whole.
with how "crazy" the world is today i feel like we need more people who will stand up against everything and unite us all under the banner of something grandiose like this.
idk i feel like it could get our minds off of the silly stuff we argue about
Arthur C. Clarke - Rendezvous With Rama please read that. Such a great novel of exploration.
You are right about bordum
It makes us appreciate life more
You know of Brian Cox?! LETS GOOOOOOOOOOOO!!!!!!!!
On the Question of how many stars are there in the Milkyway. The reason for the different answers is we get these answers by using very rigorous guesstimation. No one's actually counted all of them, we know we can't see many of them.
Add onto that, brown dwarf's are they stars? So there's a definition issue there on where the line is drawn and since they are hard to see we have little information on them.
So somewhere between 100-400 Billion is probably in the right ball park.
I just want to know before this ride is over!!
Another great video from a very intelligent lady. You're a breath of fresh air on platform full of noise. You should d listen to professor brian cox on "we are all made of stars"
There was a British scifi comedy called Red Dwarf. It was about the very last human in the universe. And there was no life other than humans in the galaxy.
It was more comedy than scifi, but it did occasionally bring up actual hard science, too.
Dwain dibley!
@@freddiebozwell7049 you know its bad when druids can use your teeth as a place of worship!
It is also possible that we are just unable to see other life forms, given that we are still only capable of perceiving a relatively small spectrum of light especially at great distances, even at close distances we are unable to see the very air we breathe. Also there have been recordings of events in history that depict humans being unable to see things directly in front of them that are beyond their understanding, if I'm not mistaken it was either Alaskan Eskimos or native Americans and something to do with ships or photographs... and maybe, they're already here.
So, I think that the impact of the knowledge of extraterrestrial life would be largely dependent on their proximity to us, and or perceived potential influence in that regard. It would likely inspire a great degree of intrigue or fear.
I don't think either that the discovery of other life forms on other planets would change our day to day life, but I think it would certainly change our future in a sense that it would lead to a shift in the way we see ourselves, a bit (and probably on a much larger scale) like when Occident rediscovered that Earth wasn't the center of the Solar system. Just this fact would, in my opinion, operate a notable change of perspective and priorities in many subjects, be they scientific, social, artistic, economic, etc.
For now, we are so incredibly egocentrics, and narcissistic than we keep acting like if all things that exist is there just for us, self-appointed ultimate form of life (funny how most religious system still emphasize that fact while preaching humility... what a paradox!).
In a nutshell: Our universe is a construct of our combined will, narrowing our perceptions in exchange for heightened clarity between us. There is only one person, and it's all of us, like facets of a gem. This is Plato's Allegory of the Cave, and his World of Forms. I, personally, think he described it really poorly, but he did sketch the rough outlines, thousands of years ago. It isn't that this world doesn't exist, the material and temporal are transitory, but the relationships and interactions among all things are actually forms of communication between ourselves. The only truly "real" things are values, in all sorts of aspects.
If there are aliens on other planets, then they, too, must inevitably be part of the great Self. Else they are extra-universal intruders born from a different construct.
I think that if we found that there is life other than on Earth, it would not have an immediate impact on our lives, but it would have an immediate impact on our way of thinking and our technological development. So eventually it would impact our lives.
Please do the video "The egg - A short story" from kurzgesagt. It's one of their best videos imo
When they said you could live around a red dwarf star inside of a simulation without feeling "bored or sad" i dont think he actually ment those specific feelings.
It's like in VR Chat.
You can be bored and sad there but that would honestly be as close to perfect as i could imagine.
Think about it.
You could spend your entire day talking to people and socializing.
You can also play games with them or work on really advanced concepts like quantum mechanics without ever having to starve or suffer.
The main idea is that you can create a world in which you feel as compfortable as possible.
And if you don't like it you can change something.
I am sure that there would still be existential dread and you would have to find some sort of meaning you could hold onto which would be hard to do in this context but it would definately erase alot of the problems we are facing now.
I think the largest change in peoples lives would be the realisation that we are more similar than we currently think. there would be much less motivation to kill for religious or political beliefs if we knew our petty actions pale in comparison to the impending change that contact would embody. for example, if you were in a petty squable with your neighbours over noise or something minor, then the city council tells you theyre demolishing your neighbourhood to build a road, would you not band together with those very same neighbours to save your homes in collective action against a more powerful threat? same for states/provinces/areas vs national/federal government, same as nations vs foreign invasions, same for humanity vs alien civilisations imo.
human ability to harness higher forms of energy is key to continued growth as a civilization...
I'm currently reading about spacetime, black holes and gravity... trying to understand the tiniest fraction of what's going on out there....
Love the nod to Galactus, the Devourer of Worlds, from Marvel Comics in the Kurzgesagt vid.
The bound on stars are all over the place because of small red-dwarfs which are hard to count, because they are dim. Those don't really matter for life, because it's not likely red-dwarfs of any kind will host life-planets, because their habitable zone is too close to the star, so the solar flares strip the planet of atmosphere (red dwarfs are active).
"Kurzgesagt TRUE Limits Of Humanity - The Final Border We Will Never Cross" is pretty humbling if you're looking for that.
I don't know what the first message by Morse code was but, when the UCLA first tested communication over the internet to Stanford (via the ARPANET), they tried to send the word LOGIN. However the system crashed after LO. So when they rebooted and tried again, they sent the full word LOGIN, but technically the first text ever transmitted over the internet was LOL
