There is one thing that we ignore. What if water isn't necessary for some extra-terrestrial life? Could that not actually INCREASE the number of planets that support life? I know what the reaction will be to what I'm about to say, but I'm going to say it. There was an episode of Star Trek: The Original Series where they commented that it was arrogant to assume that all life was carbon based. Would it not be just as arrogant to assume that all life requires water or a temperature similar to what we experience on Earth? There a just so many variables that we don't take into account when we consider the possibility of life on other planets.
That's why they say the Goldilocks zone is the ideal place for life to thrive for 'life as we know it' I think they're fully aware of this hence why they say that
I'm sure there are thousands of species of intelligent life even more intelligent than us somewhere out there, considering how huge the universe is, we can't be the only ones
Farmfield That's a stupid remark. It all boils down to how one uses their intellect. Some people appear more intelligent, but we all basically have the same brain capacity. When you really think of it like that, it becomes even more depressing when people do stupid shit.
Farmfield Our species is able to split atoms, understand that mass and energy are the same thing, develop quantum mecanics and create new elements, isn't this enough to be able to call ourselves intelligent? Sure we have huge social issues but we are still bound to our most common stress responses fear and violence, so it's intuitive that we are progressing slowly after all we were still burning "witches" only a few hundreads years ago.
Alonso Quintero - My comment here was of course sarcasm, but it's a question of definition I guess. Humans are intelligent and not very intelligent at the same time. Sure, we learned to split the atom, but the reason we did was to make a bomb. And if killing 90,000-166,000 people in Hiroshima and 60,000-80,000 in Nagasaki wasn't bad enough, we succeeded with detonating about 2000 more nuclear weapons where something like 500-600 was atmospheric tests. And also, there are christians burning 'witches' in Africa right now. The Bible is very clear that homosexuals and witches are to be killed and as long as anyone still believe the Bible should be considered relevant in any way, some people will actually do as it say's. Very sad.
Tyler H Actually I believe (and may (probably) be wrong here) that there isnt any UN or any other nation level law stating that nuclear weapons are illegal for space. In fact how would you even really control that? Realistically of course.
StrangeTerror It doesn't matter, because we first need to explore our own solar system before we go interstellar. Be happy that you'll see people in the next 50 years walking on mars. We first need to learn how to walk, before we can run a marathon.
shaddorry Oh don't get me wrong I wasn't actually trying to get into this conversation. It's just I have been drinking and my inner dickhead felt the need to clarify. Nothing to take seriously what so ever.
they would need some sort of solution for the initial chemistry to take place, however it has been theorized (pardon my lack of reference on this, but trust me when I say that some scientist have considered this possibility) that that chemistry could take place in the atmosphere of planets, especially gas giants. with that being said, it is most likely that it would have to be water, try going through a chemistry class and make any reactions happen in non-aqueous solutions. One thing water has that no other solution (or none that I know of) is that it is poler and will dissolve ionic compounds, add some heat and you have to potential for those salts to form into other compounds that would be needed for any life based on atoms. I will give you that I doesn't need Oxygen, but that is common here on earth. Take the anaerobic yeast that helps make beer and wine. ... or you know, trees haha
That's not the reason people look at it this way. The reason is that the burden of proof lies with the person claiming something. If you claim there's life based on other kinds of molecules out there, you would first need to prove the possibility of it. If there's no proven possibility at all, then there's no point in looking for it. For example, we could go looking for silicon-based life (instead of carbon), but since we would have no idea what other factors to account for (in the case of carbon-based life the other factors are oxygen and hydrogen mostly, but also nitrogen and phosphorus to a lesser extent), so we would also have no idea what to look for. There's no point in looking for something you have no reason, other than pure chance, to believe it exists. I mean, if we would find life on another planet, perhaps we could go looking for other kinds of life, but if we're not even able to find definite proof of any other lifeforms that work the same way as we do in this universe, then I don't think it would be useful in broadening our search, and focusing less on the targets that are more likely to be interesting.
It would be great if NASA got more funds really. I don't understand why some people say Space Exploration is a waste of their tax money. Probably because they are ignorant.
I understand this people very well. That does it matter, when we invest billions of dollar to find a earth-like planet, when we even not able to maintains a moon base. And to be real, a mission to Mars is still not possible. - I see not much economical benefit from this space programs at all.
Günther Lehmann I understand your concern. Simply launching a rocket would cost a lot. But once we find alternative forms of propulsion, it would be cheaper. It would also push our technology forward. The only reason people are against space exploration is probably because it doesn't not benefit them directly. Yet a stupid high defence budget does. Paying taxes= I am entitled to what I want from the government -.-
Günther Lehmann The economic benefit of space programs are endless.Almost every modern communication device are relied by satellites which is the result of space programs.
Günther Lehmann I understand these people very well. Does it matter when we invest billions of dollars to find an earth-like planet, but we aren't even able to maintain a moon base. To be real, a mission to Mars is still not possible. I dont see much economic benefit from these space programs at all. FTFY. You're welcome.
No.... they already HAVE. They have had contact for over 60 years. TH-cam Galactic Federation of Light. Also TH-cam Alien message. Greys, Reptilians, Pledians, Andromedians. Key words. TH-cam search them. They have been around for a long time. Google search "Obama Admits Aliens secretly running governments.". Read this article. TH-cam ww3 diverted. There are UFO's and aliens sightings scattered ALL OVER TH-cam. NASA does not work for the public friend. They only work for themselves and the government. They are always covering up things. Always. It's a whole new world friends.
Oliver Thorné That one guy who tells the truth and everyone points a finger at him. It's the same treatment EVERYWHERE. Are you people all really that dumb. Just ACCEPT it. Stop being a BITCH and denying it just because its strange or no one has told you. Human logic. The same thing EVERYWHERE. You guys are all acting the EXACT same way. Every video. Its the same. You're just being extremely foolish and naive... Dude there are like 60 billion literally 60 billion possibly habitable planets in our universe as far as we know. Do you know how naive you are to think that we are the biggest fish in the pond? Really? I just want to bang my head against the desk because you think just like so many people and its sad, as it is frustrating. Do you know what an defense mechanism is? If you were to accept aliens exist and all what I said was true your brain would have to readjust and your whole world would be flipped upside down. Its quite a transition. Its sad to know however that most people much rather continue to believe a lie. Pity. Oh well. If you are not interested in alien life or at least accepting that it exists then why come on these videos? Why are you here?
Heatseeker19 I am 100% convinced that aliens exist, I barely even think it's a debate at this point. What I am extremely sceptical about, however, is that aliens have visited the U.S. Not the entire earth, only the U.S. That, to me, seems very unlikely. Also, people in general are way too incompetent to be able to cover up such a thing as aliens.
Oliver Thorné Dude... they've been coming to this planet even BEFORE the US existed. Its not only the US they have been visiting. There have been TH-cam clips of them in China. An alien space ship. It was crazy it was just flying and then the camera guys ran after and decided to follow it and saw that it landed and some small guy came out and the people got freaked the shit out of and ran. Hahaha it was brilliant. Deviated a bit but the fact of the matter is for matters concerning ET's the cover up can be very sloppy because most people will cover it up themselves with their own defense mechanisms and doubt. I mean just look at the 7 people who liked your comment. They much rather believe I'm crazy than to accept the truth as strange and as bizarre as it may seem. Its still true or at least closer to the truth than their perceived reality.
Now for the more interesting question: What percentage of habitable planets harbor complex life, and energy rich environments. Two key ingredients for intelligent life.
The real question should be: Should we even try to reach them? The chances that our alien neighbours could see us more as the dinner than a buddy to have dinner with is extremely high, so should we even risk such a thing?
If and when we do discover alien life, we wouldn't be able to reach them for thousands or even millions of years, depending on how far away the planets star is, due to the vast distances between starts.
Forgetting one important fact. Alien life will mostly will NOT even remotely resemble OUR way of what we call LIFE and how it is lived, formed here on earth, or could form.
Without a shadow of a doubt I would say that is certainly the case if there is some kind of life on a planet like Jupiter. But for the planets that are similar to Earth, don't you think the life could look similar? I do find that even more interesting though, the life that would be so different from us.
Leila Smith JUPITER? You do know that Jupiter is a gas giant, right? That aside, yes alien life will almost assuredly be as foreign to us as... as... Well... there isn't really a suitable metaphor because anything I would draw comparison to would be far too familiar. If you have a proper look at Taxonomy, Philology, and Evolution. You can clearly see that if at any point some ancient rodent was crushed by a larger creature. Mammals would never exist and some other order of creature would take our place. There would be no man kind in fact there would be no dog, no elephant, no horse, no Dolphin or any other mammal for that matter. Look the point is in the massive timescale that is evolution, anything could be here, in our place something greater or worse. We'll never know but we'll find out. Up there in the stars, but what we find will be so fascinating and so ALIEN we won't know what to expect.
I don't really care about how many planets out there could hold microbes and such, I want to know how many that can hold bigger and more complex creatures we find here on Earth!
Oh really? What about the fact that they can be INHABITED? Of course human logic who cares take it anyway. smh its an evil way of thinking that if all the aliens shared then we probably wouldn't exist because they would of enslaved us a long time ago. Like the covenant in Halo.
Unsurprising. 10 years ago, if you had asked top scientific minds whether life could be supported beneath the Earth's crust or subterranean Antarctica, you'd be laughed at for even asking. Both now known to support not only life, but an abundance of it. I trust science when it comes to many things, but the ability to decipher what environments can and cannot support life is one of those area's where they really have no clue.
Indeed, it's no coincidence that Earth is right in the middle of the Goldilocks zone. Evolution has shown that all life adapts to its surrounding environment. To then point to our particular environmental conditions and say "This is what life needs to survive" seems almost religiously arrogant.
They have actually done the calculations based on quantum mechanics that this would occur and the observable universe isn't that vast. The argument is that if there are an infinite amount of universes, than there would be infinite copies of everything, because you know.. infinite. But in this universe, no probably not.
05candyman The only reason it is "impossible" is because we deem it impossible with the little information we have (even tho it might seem like alot to us I doubt that it is ALOT in the big picture xD)
Personally I would say the idéa of unrecognizable life is much more interesting. I love that with Star Trek, like when they find a stellar cloud with an intellect - that's the cool stuff. :D
Scientists should also assume that life can begin and evolve and not be carbon-based like we are. Looking for other forms of life that are like us seems to me to set us up for failure by confirmation bias. Non carbon-based life would also exponentially increase the amount of potentially habitable planets. Maybe sub-surface life is actually a thing and there are (more) advanced life-forms living under their planets surface in a Rapture like colonization that we are unable to detect. Or maybe it would be best to assume that most extra-solar planets have the possibility to house life? We do have an idea of what kind of extra-solar planets most likely have no chances or harboring life, so that should also help.
THEY FORGOT ANOTHER VARIABLE YOUR APPLYING EARTHLY STANDARDS OF WHAT WE CONCEIVE IS NEEDED TO CREATE LIFE LIKE WATER AND CARBON HOW DO KNOW SOME LIFE-FORMS ON OTHER WORLDS CAN OR CAN'T ARISE FROM OTHER ELEMENTS THAT WE KNOW OF OR THAT ONLY EXIST ON THAT SPECIFIC PLANET?
Who knows life could be based on another element but the reason many scientists go based on carbon is because its ability to form multiple complex and stable bonds anyone who has taken basic chemistry will know this and anyone who has taken organic chemistry very much knows about this in the environment. As for finding other elements this is again basic chemistry due to the fact that any particular element is simply a composition of fundamental subatomic particles which numbers vary due to the element. If I'm not mistaken the 'heaviest" and most recent we found was 115? Regardless this is what matter is so I'm not sure what you mean by discovering new elements elsewhere.
Diego lechuga One needs only a basic understanding of the elements and what they are made of to understand that we have "found" every single naturally occurring element. What makes elements different from each other is the number of protons they have. The simplest is hydrogen at the beginning of the periodic table with one proton, and at the end of the periodic table there are the heaviest and most unstable elements with the most protons. The heaviest of the elements are too unstable to exist in nature and are made synthetically. So you see, all the gaps in the periodic table are filled. There is no room left for more elements!
Hence the term "Life as we know it." :3 If you include the possibility of there being hugely different forms of life than every planet everywhere could probably support life lol
Just going on the number of planets we suspect have the right conditions for life as we know it, I figure it a safe bet to expect finding complex life on about 30% of those planets but probably 80% will have only microbial life. It would be awesome is complex life was far more abundant but I unfortunately have some doubts because of the countless ways complex life is subjects to mass extinctions on scales greater than we've seen on Earth given just how hostile the universe can be. Earth hasn't been fried by a pulsar, pulverized by another planet or especially massive asteroid while life was present, swallowed by a black hole, roasted or annihilated by its own sun going supernova, all manner of things we have observed in the universe that Earth hasn't been subjected to. Intelligent life I fear is going to be extremely rare but yet we know it is possible as being proof of it ourselves.
What would happen if we encountered intelligent life and neither lifeform was able to comprehend the other's form of intelligence? Even worse if just one could. Nevermind, im going to write a sci-fi short story.
Dammit i'm sure some of the other aliens discovered aliens already. We just need to be smarter! But we're getting there. I think there are a shit bunch of aliens out there. We are just too far to get to them.
Maybe, just maybe we are the first aliens in the galaxy to get to such technological advanced society and everyone else is behind us? It would make sense if they are out there! I mean, technological advancement happens so quickly when we get to this point we are now, so the first ones that get there would colonize the entire galaxy before the others get a chance!
GeneralBlackNorway The problem is this: Our civilization started about 12000 years ago, and with the exponential growth we have now one can assume that within the next 5000 years we will either be dead or have developed into something like Q in Star Trek. This means that we would be recognized as a civilization for only about 17000 years... The universe is 13,7 billion years old, so during that time there could have been 805882 civilizations that never even existed at the same time! -If we assume that their time as a recognizable civilization is similar to ours.
ah but you forget that our species is young, if there was a species like ours out there It my be 30'000 times older than our one, so we just maybe might be a long lasting incredible spices and make sure we don't die out.
Merecir Remember that even though the universe is nearly 14 billion years old that does not mean there have been life in all of that time. One thing that is necessary for life to even exist is supernovas. So at least 35 million years must pass. That's not too much though in comparison to the universe. However the nebula left behind must then form a new star. This is a process I can imagine can take very long. Also the time it took from the birth of our sun to us humans evolving was a staggering 5 billion years. That alone leaves us with less then 7 billion years until today. Now for a nebula to collapse into a large star it take minimum 100 thousand years. For a star like our sun it would take 10 million. So basically about 50 million years. So we have at least 5.05 billion years of no intelligent life in this universe. I'm sure other factors can be found that would make the gap of time between the first possibilities of intelligent life to evolve and us humans today.
it be amazing if we found life on other planets it would be even more amazing if we could find away to travel these huge distances in space to get there promptly. Hurry up warp speed science
If planets simular to ours egsist , the life simular to ours does as well. But we all forget 1 thing thats important:"Life can be manefested in a lot of vais!!!" To us life is based on water and oxigen, but to some other spicies it could based on somthing else, like fire or even vacum, of some kind. Posibilities of life are endles, as for now we onli know this for, but what about the things we dont? Well there are a lot of them so if we would to try and search for them, I'm positive we would be amazed of what we would find!!! ;-) B-) :-)
There actually aren't to many possibilities for the materials that make up life. For us is carbon mostly, but it could be possible to have silicon based life. Its impossible to have have a life form be made of fire as fire is firstly not an element and secondly a combustion reaction.
Let me ask u some thing. What is the energy that keep's our body's form falling apart??? If u know that then u know what I was talking about. And there are a lot of things we don't know. Like for example whats smalar then 10th of a neutron? ;)
Naruto Uzumaki The force that keeps our body together is the electromagnetic attraction between molecules that form our body. There are a lot of things we don't know, but we do know that life cannot be formed from pure energy. Nothing is smaller than a tenth of a neutron, that is because our concept of 'smallness' breaks down at that point and the strong force between quarks dominate. Please keep your New Age Psudo-Science BS elsewhere.
There is life in the Mariana trench at 11km depth, so life not only could but does exist at over 5 km deep in the ocean. Thanx for this awsome show and interesting episode. Hope we find some life elsewhere in the universe soon.
The only thing about the Gliese 667C b is that it has a phenomenon on it that is called the runnaway greenhouse gas effect. Meaning that greenhouse gasses can't be trapped underneath it's atmosphere, resulting in no liquid water. Sorry to burst your bubble.
Problem with trying to guess the percentage of planets that could potentially support life is that we don't know about all the different kinds of life there could be. I remember hearing something about scientists theorizing that it could be possible that there are silicone based lifeforms. If I had to guess based off our current understanding of life, I would guess between 1-10% of planets could support earth-like life. As for how long until we discover life in any form (bacterial included) I don't have a time frame but instead two points in time. Either we'll find it on the Mars mission, or we'll find it once we complete warp drive and gain the ability to travel to other solar systems.
not all Christians are like that. this is mostly just a subset known as YEC's, or "Young Earth Creationists". many (or possibly most) people don't share the YEC mindset, even if otherwise religious.
I think about 20-40% of all planets in the galaxy have had life, have life, or will have life. I don't think there is any way to predict when we will find interplanetary life. After all, the rate at which we are advancing is always fluctuating - it has gotten much faster in recent times, and how do we know we won't hit a roadblock again sometime soon?
LOL Steven, you can't be serious. there is NOT an unlimited number of planets in the universe. Kox is right, all matter in the universe is finite. I'm not going to explain myself further because I'm pretty sure you're trolling.
-“It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.” [Douglas Adams]
There is no way we are the only living thing in this galaxy yet alone this universe. I honestly think even though it sounds sci-fi and a bit mad to you boring folk that it's like Star Trek out there. I really hope we find something on Europa.
***** I'm gonna go cup half full on this one mate, we exist so I'm sure by the law of averages something else does too. Some of the basic building blocks of life can be found on asteroids along with ice, and we all know what happens when there's water. So far 100% of the planets we know for certain have liquid water on them have complex life. Earth mate look it up!
The question isn't whether there is life out there for me that is without a doubt that in the infiniteness of the universe at least one other planet could spontaneously generate life, the question for me is how on Earth will we get there. It would take us literally trillions of years to get to Alpha Centuari A (The closest star to Earth) with current technology and it is most likely that an Earth like planet would be even further away. Also considering that you cannot travel faster than the speed of light it would take us 1000s of years to develop the technology to travel there and even then it would take us hundreds of years to get there. So really I don't think there is much point of us considering the possibility of Alien life, or intelligent life. I really think the term intelligent life is very vague as humans even 1000 years ago considered themselves intelligent so for all we know aliens are laughing at our idea that the Internet is advanced. So really I think the prospect of humans and intelligent aliens ever coexisting will not happen simply because of the logistical side of things unless it were possible to travel faster than the speed of light.

If it wasn't for the Dark Age minded, science hating, warmongering abrahamic religions, we could very well be "Star-Trekking" by now. Imagine if only half of the funds allocated to the war machine was put into actual scientific exploration.
look up on youtube the documentary Evacuate Earth Escape from a Neutron Star (think its called that pretty sure) it shows how we could travel to another planet even though the trip is 80 years and the had 75 years to build the ship was built to harbor a million people so ya if we had the money and determination we could :)
Dyvim Tvar yes, but Star Trek tech is a type 2 technology, meaning they can harness the power of their mother star for energy. We humans are type 0, we get our energy from dead plants and animals, fossil fuels. And it will take a few centuries to make it to type 1, controlling the power of the planet. We have a loooong way to go.
VinceLovesToast I have seen it actually, but realistically speaking that is not going to happen and I am not sure if our technology could advance by so much so quickly and that was on a planet that was relatively close to ours in reality we will most likely have to travel much further.
Scott Andrew True but for me the problem is not just conquering speed, it is working out how humans can be safe at such speeds because we would be going so fast at even half the speed of light that it would kill us due to G-Forces. I know we seem to be a long way away from developing type 2 technology but the fact is humans are advancing rapidly so it could be researched much quicker. In 80 years (the average lifespan today in the UK) we went from using horses and carriages to sending man on the moon so you never know how different things could be 80 years from now.
Turns out 100% of those billions are too far away and too dangerous to get to. So no matter how much like earth they are we're stuck here. However, if we tax the religious and use that money to invest in space stuff maybe we could do it. Just tell them we found a space gate to their particular version of the after life and the tithing will pour in.
What? Sorry I don't get you esoteric reply. Should I be amused or insulted? Well 3 people got it so good for you. Moreover, my hat collection is none of your business.
The reasons that researchers decided to expand the Goldilocks Zone were more complicated then you described, right? I was just chuckling at the idea of scientists realizing that they forgot about clouds and quickly changed their numbers.
WE ARE ALONE or shall i say where is the evidence no one talks to us its kinda depressing with all these high estimates yet no single fuck is given by the rest of milkway ffs i just want to meet one intelligent species from another planet and i will die a happy man even though i might freak out upon seeing them for the first time. and no one cares about microbial life
Our universe is fairly new so finding intelligent life out there is a pretty hard thing to do right now. Don't get your hopes up because of all of the sci-fi movies you have been watching.
the key to finding this and pushing our technology to its limits for further research and missions is a more scientifically inclined mind state for everybody, we need everyone's support and willingness to invest
I always sit here and think that someone from another planet could be doing the same thing I am and it always gets me excited. But I know that I probably won't be alive long enough to see us travel to different planets and find life.
If Life isn't synonymous with being carbon-based, then even MORE bigger than before. If you want a percentage, then maybe 55%? The real question being ofcourse, what qualifies as "life"? And just like that, from the tree of one question abounds countless number of science fictions! :D
Alonso Quintero If that be the case, then isn't the whole Universe itself, alive?You know, as the Universe evolves where the most stable atoms/particles/gas clouds win over the ones which were unstable? And the unstable ones either fizzle out as energy and multiple breakdown products or itself transmutates into another element/change it's order to form a gas cloud/star/planet/asteroid? :O Bascially a constant adaptation process to adapt very well to it's environment.
Since it takes something like 70 thousand years to reach the next star system I think finding intelligent life is out the realm of possibilities right now until we find a faster we to space travel, which I doubt very much will happen in my life time. That said, I think there's an extreme possibility that we could find microbial life in our solar system if we are able to land & explore planets that we know could potentially support life like Mars or Europa (not a planet, but I'm sticking with that example)
Ok Trace, I have a question. Could you tell us, what would actually happen if we find life on another planet, that is like 30 light years away? What would we do? Like would we send a probe on that planet, even if it that far away?
***** Yeah but if intelligent life would be there, we would have to consider the fact that they might be hostile... I mean we wouldn't just recklessly message them "Hello!!!", you know what I mean. I was asking if they have like prepaired procedure, what to do or who to inform when they find extra terrestrial life. Tartar Shoes, thanks for telling me this. I didn't really pay attention when I was writing this. Thank you!
***** Sending a message to a planet 30+ light years away would be impractical. I mean, they would probably do it regardless assuming they had the capability, but you have to remember how long it would take to actually get there. If you were sending it by radio waves, by the time our message got to the planet 30 light years away the guys who sent that message would be long dead. Sending a probe with current technology would be pretty much impossible.
We can find all lives in the universe within a lifetime. Using atomic powered spaceships we can reach 99% the speed of light. We can build such ships at a constant rate. But each ship would travel to the nearby star and create a factory that will build more ships. This would mean that very quickly we can cover the entire known universe. And all of this would actually be very inexpensive.
Well considering that our universe is practically ever expanding at a speed faster than that of the speed of light and considering the fact that there are more galaxies than the amount of all life on earth summed up together into one number and also considering that each galaxy has 60 billion planets that can sustain life, then I think that about at least 2% of all of the planets in the universe have life, which is still a pretty large number.
my opinion: less than 1% support life when will we find it? never, we'll either destroy ourselves, die off by other means, or we'll realize that it's impossible to travel interstellar no matter the tech, and give up on it.
Do you think 1000 years ago, when people looked up at the tiny glimmer of light that the planet Mars is in our night sky, that they could ever have imagined a human made object would be roaming round it taking samples and sending photos back to Earth for us to see? 1000 years ago that idea would've been beyond comprehension. Who's to say what we will see or do in the next 1000 years!
I get into arguments about this one all the time with people, and I was just wondering if anyone out there could tell me if this doesn't make sense: Statistically speaking, there is no other planet with life, considering that Earth is the only statistic we have. However in probability we could assume that at least 1 in every 8 planets has life, considering that our planet is that 1 out of the 8 in our solar system.
The number of possible planets that could support life in the universe could be infinity if the universe keeps expanding and creating new planets...etc. I think we will discover new life when we have better telescopes or when we can send people to one of those planets within a reasonable time.
I'm positive that there has been, is, or will be other life in the universe. The problem is, the universe is so vast and so old that we will either not exist at the same time in a close enough distance to meet, or any intelligence we meet will be vastly inferior or vastly superior.
Another thing to consider is that if we're talking about intelligent life, then technology could allow such life to live on a planet that would not have been habitable without technology. Those seemingly uninhabited planets could be home to non-native colonists living inside bubble domes.

There is nothing I want more than to be alive by the time we discover life on other planets.
not gonna happen sorry
I demand to know where you bought that shirt...
Probably got it from woot.
I think around over a trillion planets have life....couple billions have intelligent life. It might be much much more than that though
There is one thing that we ignore. What if water isn't necessary for some extra-terrestrial life? Could that not actually INCREASE the number of planets that support life? I know what the reaction will be to what I'm about to say, but I'm going to say it. There was an episode of Star Trek: The Original Series where they commented that it was arrogant to assume that all life was carbon based. Would it not be just as arrogant to assume that all life requires water or a temperature similar to what we experience on Earth? There a just so many variables that we don't take into account when we consider the possibility of life on other planets.
That's why they say the Goldilocks zone is the ideal place for life to thrive for 'life as we know it' I think they're fully aware of this hence why they say that
Like the Xenomorph, It's a silicone base lifeform.
I'm sure there are thousands of species of intelligent life even more intelligent than us somewhere out there, considering how huge the universe is, we can't be the only ones
You're implying we're an intelligent species, I dunno about that.
Farmfield That's a stupid remark. It all boils down to how one uses their intellect. Some people appear more intelligent, but we all basically have the same brain capacity. When you really think of it like that, it becomes even more depressing when people do stupid shit.
Farmfield
Our species is able to split atoms, understand that mass and energy are the same thing, develop quantum mecanics and create new elements, isn't this enough to be able to call ourselves intelligent? Sure we have huge social issues but we are still bound to our most common stress responses fear and violence, so it's intuitive that we are progressing slowly after all we were still burning "witches" only a few hundreads years ago.
Alonso Quintero - My comment here was of course sarcasm, but it's a question of definition I guess. Humans are intelligent and not very intelligent at the same time. Sure, we learned to split the atom, but the reason we did was to make a bomb. And if killing 90,000-166,000 people in Hiroshima and 60,000-80,000 in Nagasaki wasn't bad enough, we succeeded with detonating about 2000 more nuclear weapons where something like 500-600 was atmospheric tests.
And also, there are christians burning 'witches' in Africa right now. The Bible is very clear that homosexuals and witches are to be killed and as long as anyone still believe the Bible should be considered relevant in any way, some people will actually do as it say's. Very sad.
Yeaaaah 60 billion planets is cool and all.. But it would be nice if we could land on ONE.. preferably while I'm still alive please.
Tyler H
Actually I believe (and may (probably) be wrong here) that there isnt any UN or any other nation level law stating that nuclear weapons are illegal for space. In fact how would you even really control that? Realistically of course.
StrangeTerror It doesn't matter, because we first need to explore our own solar system before we go interstellar. Be happy that you'll see people in the next 50 years walking on mars. We first need to learn how to walk, before we can run a marathon.
shaddorry
Oh don't get me wrong I wasn't actually trying to get into this conversation. It's just I have been drinking and my inner dickhead felt the need to clarify. Nothing to take seriously what so ever.
I don't care how many planets have intelligent life in our Galaxy. I just want us to find one.
Sorry I meant galaxy
This isn't really news for me.....it isn't even slightly surprising honestly.
Any planet could have life! Why do they NEED water, and oxygen? Just because we need it and all multicellular life on earth does? C'mon!
finally!!!!!!!!!
they would need some sort of solution for the initial chemistry to take place, however it has been theorized (pardon my lack of reference on this, but trust me when I say that some scientist have considered this possibility) that that chemistry could take place in the atmosphere of planets, especially gas giants. with that being said, it is most likely that it would have to be water, try going through a chemistry class and make any reactions happen in non-aqueous solutions. One thing water has that no other solution (or none that I know of) is that it is poler and will dissolve ionic compounds, add some heat and you have to potential for those salts to form into other compounds that would be needed for any life based on atoms.
I will give you that I doesn't need Oxygen, but that is common here on earth. Take the anaerobic yeast that helps make beer and wine. ... or you know, trees haha
That's not the reason people look at it this way. The reason is that the burden of proof lies with the person claiming something. If you claim there's life based on other kinds of molecules out there, you would first need to prove the possibility of it. If there's no proven possibility at all, then there's no point in looking for it.
For example, we could go looking for silicon-based life (instead of carbon), but since we would have no idea what other factors to account for (in the case of carbon-based life the other factors are oxygen and hydrogen mostly, but also nitrogen and phosphorus to a lesser extent), so we would also have no idea what to look for. There's no point in looking for something you have no reason, other than pure chance, to believe it exists.
I mean, if we would find life on another planet, perhaps we could go looking for other kinds of life, but if we're not even able to find definite proof of any other lifeforms that work the same way as we do in this universe, then I don't think it would be useful in broadening our search, and focusing less on the targets that are more likely to be interesting.
very well put! couldnt agree more Joey
they should first research what life is, it might be that all the planets or whole universe is alive too
It would be great if NASA got more funds really. I don't understand why some people say Space Exploration is a waste of their tax money. Probably because they are ignorant.
I understand this people very well. That does it matter, when we invest billions of dollar to find a earth-like planet, when we even not able to maintains a moon base. And to be real, a mission to Mars is still not possible. - I see not much economical benefit from this space programs at all.
Günther Lehmann I understand your concern. Simply launching a rocket would cost a lot. But once we find alternative forms of propulsion, it would be cheaper. It would also push our technology forward. The only reason people are against space exploration is probably because it doesn't not benefit them directly. Yet a stupid high defence budget does. Paying taxes= I am entitled to what I want from the government -.-
Günther Lehmann It shouldn't be about the economy it should be about improving mankind as a whole.
Günther Lehmann The economic benefit of space programs are endless.Almost every modern communication device are relied by satellites which is the result of space programs.
Günther Lehmann I understand these people very well. Does it matter when we invest billions of dollars to find an earth-like planet, but we aren't even able to maintain a moon base. To be real, a mission to Mars is still not possible. I dont see much economic benefit from these space programs at all.
FTFY. You're welcome.
Gawd, don't scroll down to the comment section. So many rocket-scientists and know-it-alls your eyes will bleed.
That is sooooo exciting!!! !D
C'mon NASA, find that alien life already! Like, in our lifetime, please.
No.... they already HAVE. They have had contact for over 60 years. TH-cam Galactic Federation of Light. Also TH-cam Alien message. Greys, Reptilians, Pledians, Andromedians. Key words. TH-cam search them. They have been around for a long time. Google search "Obama Admits Aliens secretly running governments.". Read this article. TH-cam ww3 diverted. There are UFO's and aliens sightings scattered ALL OVER TH-cam. NASA does not work for the public friend. They only work for themselves and the government. They are always covering up things. Always. It's a whole new world friends.
Heatseeker19 There will always be that one guy.
Oliver Thorné That one guy who tells the truth and everyone points a finger at him. It's the same treatment EVERYWHERE. Are you people all really that dumb. Just ACCEPT it. Stop being a BITCH and denying it just because its strange or no one has told you. Human logic. The same thing EVERYWHERE. You guys are all acting the EXACT same way. Every video. Its the same. You're just being extremely foolish and naive... Dude there are like 60 billion literally 60 billion possibly habitable planets in our universe as far as we know. Do you know how naive you are to think that we are the biggest fish in the pond? Really? I just want to bang my head against the desk because you think just like so many people and its sad, as it is frustrating.
Do you know what an defense mechanism is? If you were to accept aliens exist and all what I said was true your brain would have to readjust and your whole world would be flipped upside down. Its quite a transition. Its sad to know however that most people much rather continue to believe a lie. Pity. Oh well.
If you are not interested in alien life or at least accepting that it exists then why come on these videos? Why are you here?
Heatseeker19 I am 100% convinced that aliens exist, I barely even think it's a debate at this point. What I am extremely sceptical about, however, is that aliens have visited the U.S. Not the entire earth, only the U.S. That, to me, seems very unlikely.
Also, people in general are way too incompetent to be able to cover up such a thing as aliens.
Oliver Thorné Dude... they've been coming to this planet even BEFORE the US existed. Its not only the US they have been visiting. There have been TH-cam clips of them in China. An alien space ship. It was crazy it was just flying and then the camera guys ran after and decided to follow it and saw that it landed and some small guy came out and the people got freaked the shit out of and ran. Hahaha it was brilliant. Deviated a bit but the fact of the matter is for matters concerning ET's the cover up can be very sloppy because most people will cover it up themselves with their own defense mechanisms and doubt.
I mean just look at the 7 people who liked your comment. They much rather believe I'm crazy than to accept the truth as strange and as bizarre as it may seem. Its still true or at least closer to the truth than their perceived reality.
Now for the more interesting question: What percentage of habitable planets harbor complex life, and energy rich environments. Two key ingredients for intelligent life.
Ok, we find them, but the real question is - Can we reach them? :)
or can they reach us? ;)
no logic.. xD
The real question should be: Should we even try to reach them? The chances that our alien neighbours could see us more as the dinner than a buddy to have dinner with is extremely high, so should we even risk such a thing?
Pretty much what @adagioforstrings007 said.
If and when we do discover alien life, we wouldn't be able to reach them for thousands or even millions of years, depending on how far away the planets star is, due to the vast distances between starts.
I LOVED this. Seriously, the whole "other planets may support life" thing is IMMENSELY interesting to me. Thanks, DNews!!!
What about moons that can support life?
Forgetting one important fact. Alien life will mostly will NOT even remotely resemble OUR way of what we call LIFE and how it is lived, formed here on earth, or could form.
And if alien life exists, Genetic Xenophobia will kick in. Assuming the alien life is more powerful than we are, we would be obliterated.
Without a shadow of a doubt I would say that is certainly the case if there is some kind of life on a planet like Jupiter. But for the planets that are similar to Earth, don't you think the life could look similar? I do find that even more interesting though, the life that would be so different from us.
But the biologists will probably doom us all if they have super-advanced tech. Cuz you know, dissecting and all that.
well i think that aliens would have some similarities with us...
Leila Smith JUPITER? You do know that Jupiter is a gas giant, right? That aside, yes alien life will almost assuredly be as foreign to us as... as... Well... there isn't really a suitable metaphor because anything I would draw comparison to would be far too familiar. If you have a proper look at Taxonomy, Philology, and Evolution. You can clearly see that if at any point some ancient rodent was crushed by a larger creature. Mammals would never exist and some other order of creature would take our place.
There would be no man kind in fact there would be no dog, no elephant, no horse, no Dolphin or any other mammal for that matter. Look the point is in the massive timescale that is evolution, anything could be here, in our place something greater or worse. We'll never know but we'll find out. Up there in the stars, but what we find will be so fascinating and so ALIEN we won't know what to expect.
300% of planets out there have life on them!!!!
In an unrelated note, I never exactly figured out why I did so poorly in math in grade school.
Yet to find actual proof of any life. You'd think that there would be atleast one type of creature out the Smarter than us and beyond Advanced
iAMLegend2v Smarter than 'us'? No.
Smarter than me? Most definitely a 300% yes.
Damn I'm so exited to explore different planets now.
It's a bummer that I won't be alive during that time
Until this video I thought I was alone in using both kilo-meter and kilom-eter in one sentence.
i imagine aliens, making videos and talking about stuff like this.
Come on, let's go already. Let's find Piccolo's homeland :D
Cool Shirt. Very Informational Vid :D. Love DNews
I WANT THAT SHIRT!!
how long until we make first contact with the turians?
I don't really care about how many planets out there could hold microbes and such, I want to know how many that can hold bigger and more complex creatures we find here on Earth!
60 billion planets we could potentially claim as our own :D
Empire of Mankind, here we come!
Oh really? What about the fact that they can be INHABITED? Of course human logic who cares take it anyway. smh its an evil way of thinking that if all the aliens shared then we probably wouldn't exist because they would of enslaved us a long time ago. Like the covenant in Halo.
Heatseeker19
*See the words of a true heretic!*
Heatseeker19(Grunt voice) heretic!! heretic!!
Now we all we need to find such a planet!
And don't give that "The existence of aliens would cause panic and riots on Earth'' bullshit!
Unsurprising. 10 years ago, if you had asked top scientific minds whether life could be supported beneath the Earth's crust or subterranean Antarctica, you'd be laughed at for even asking. Both now known to support not only life, but an abundance of it. I trust science when it comes to many things, but the ability to decipher what environments can and cannot support life is one of those area's where they really have no clue.
Indeed, it's no coincidence that Earth is right in the middle of the Goldilocks zone. Evolution has shown that all life adapts to its surrounding environment. To then point to our particular environmental conditions and say "This is what life needs to survive" seems almost religiously arrogant.
***** I like turtles.
If there is life in our solar system, I'd say within the century. Within the millennium if there is any outside.
Technically, since the universe is so vast, it is PERFECTLY possible that there could be an almost exact copy of earth somewhere.
They have actually done the calculations based on quantum mechanics that this would occur and the observable universe isn't that vast. The argument is that if there are an infinite amount of universes, than there would be infinite copies of everything, because you know.. infinite. But in this universe, no probably not.
60billion planets in are galaxy alone can hold life, that is crazy considering how their are billions of galaxies.
05candyman Maybe infinite? ;) This really gets me going.
Who knows? :P
05candyman Well, nothing in the observable universe is infinite, but as far as we know, the size of the whole universe could be infinite.
05candyman The only reason it is "impossible" is because we deem it impossible with the little information we have (even tho it might seem like alot to us I doubt that it is ALOT in the big picture xD)
Humans in a million years? How doubtful.
God i love this channel informative and short vids and laci too
There is Life out there, i m sure about that. But is there Coffee and Beer out there ??? I M Intrusting to know that :)
This is amazing!! :D
In 10000000 years weekly space update will have probably turned into weekly dimension update or even weekly universe update
assuming humans are still alive
All is alive;we, the universe are all connected. We are all energy, vibration, & frequency.
I'm sure there are lots of planets that support some form of recognizable life. But I honestly doubt we'll ever find it.
Personally I would say the idéa of unrecognizable life is much more interesting. I love that with Star Trek, like when they find a stellar cloud with an intellect - that's the cool stuff. :D
thank you! I've always thought it was ridiculous that we were putting such harsh restrictions on what could harbor life. This makes me excited
Scientists should also assume that life can begin and evolve and not be carbon-based like we are. Looking for other forms of life that are like us seems to me to set us up for failure by confirmation bias. Non carbon-based life would also exponentially increase the amount of potentially habitable planets.
Maybe sub-surface life is actually a thing and there are (more) advanced life-forms living under their planets surface in a Rapture like colonization that we are unable to detect.
Or maybe it would be best to assume that most extra-solar planets have the possibility to house life? We do have an idea of what kind of extra-solar planets most likely have no chances or harboring life, so that should also help.
THEY FORGOT ANOTHER VARIABLE
YOUR APPLYING EARTHLY STANDARDS OF WHAT WE CONCEIVE IS NEEDED TO CREATE LIFE LIKE WATER AND CARBON HOW DO KNOW SOME LIFE-FORMS ON OTHER WORLDS CAN OR CAN'T ARISE FROM OTHER ELEMENTS THAT WE KNOW OF OR THAT ONLY EXIST ON THAT SPECIFIC PLANET?
Jeenius Foo and we keep on finding new stuff (elements)... amazing...
***** yes there could exist life without carbon ... life could also be silicon based ...
Who knows life could be based on another element but the reason many scientists go based on carbon is because its ability to form multiple complex and stable bonds anyone who has taken basic chemistry will know this and anyone who has taken organic chemistry very much knows about this in the environment. As for finding other elements this is again basic chemistry due to the fact that any particular element is simply a composition of fundamental subatomic particles which numbers vary due to the element. If I'm not mistaken the 'heaviest" and most recent we found was 115? Regardless this is what matter is so I'm not sure what you mean by discovering new elements elsewhere.
Diego lechuga One needs only a basic understanding of the elements and what they are made of to understand that we have "found" every single naturally occurring element. What makes elements different from each other is the number of protons they have. The simplest is hydrogen at the beginning of the periodic table with one proton, and at the end of the periodic table there are the heaviest and most unstable elements with the most protons. The heaviest of the elements are too unstable to exist in nature and are made synthetically. So you see, all the gaps in the periodic table are filled. There is no room left for more elements!
Hence the term "Life as we know it." :3 If you include the possibility of there being hugely different forms of life than every planet everywhere could probably support life lol
Just going on the number of planets we suspect have the right conditions for life as we know it, I figure it a safe bet to expect finding complex life on about 30% of those planets but probably 80% will have only microbial life. It would be awesome is complex life was far more abundant but I unfortunately have some doubts because of the countless ways complex life is subjects to mass extinctions on scales greater than we've seen on Earth given just how hostile the universe can be. Earth hasn't been fried by a pulsar, pulverized by another planet or especially massive asteroid while life was present, swallowed by a black hole, roasted or annihilated by its own sun going supernova, all manner of things we have observed in the universe that Earth hasn't been subjected to. Intelligent life I fear is going to be extremely rare but yet we know it is possible as being proof of it ourselves.
What would happen if we encountered intelligent life and neither lifeform was able to comprehend the other's form of intelligence? Even worse if just one could. Nevermind, im going to write a sci-fi short story.
LOVE THE SHIRT MAN!
Just because we need oxygen or heat and water doesn't mean ALL form of life need it
Fascinating! I think there is life out there, and a lot of it. I don't think that we will find out any time soon or ever...
Dammit i'm sure some of the other aliens discovered aliens already. We just need to be smarter! But we're getting there. I think there are a shit bunch of aliens out there. We are just too far to get to them.
Maybe, just maybe we are the first aliens in the galaxy to get to such technological advanced society and everyone else is behind us? It would make sense if they are out there! I mean, technological advancement happens so quickly when we get to this point we are now, so the first ones that get there would colonize the entire galaxy before the others get a chance!
GeneralBlackNorway The problem is this:
Our civilization started about 12000 years ago, and with the exponential growth we have now one can assume that within the next 5000 years we will either be dead or have developed into something like Q in Star Trek.
This means that we would be recognized as a civilization for only about 17000 years...
The universe is 13,7 billion years old, so during that time there could have been 805882 civilizations that never even existed at the same time! -If we assume that their time as a recognizable civilization is similar to ours.
ah but you forget that our species is young, if there was a species like ours out there It my be 30'000 times older than our one, so we just maybe might be a long lasting incredible spices and make sure we don't die out.
And don't forget that our planet is pretty young when you compare it to most of just our galaxy even.
Merecir Remember that even though the universe is nearly 14 billion years old that does not mean there have been life in all of that time. One thing that is necessary for life to even exist is supernovas. So at least 35 million years must pass. That's not too much though in comparison to the universe. However the nebula left behind must then form a new star. This is a process I can imagine can take very long. Also the time it took from the birth of our sun to us humans evolving was a staggering 5 billion years. That alone leaves us with less then 7 billion years until today. Now for a nebula to collapse into a large star it take minimum 100 thousand years. For a star like our sun it would take 10 million. So basically about 50 million years. So we have at least 5.05 billion years of no intelligent life in this universe. I'm sure other factors can be found that would make the gap of time between the first possibilities of intelligent life to evolve and us humans today.
10 bucks says at least one pokemon will be out there...
seriously where did you get that pokemon shirt
LOL saw you on a recent video
I saw that one for purchase at "Level Up Studios".
I like that you ask "what percentage" and not "if" :)
well even if you deny there being extra-terrestrial life one planet in our universe has to support it... us :3
it be amazing if we found life on other planets it would be even more amazing if we could find away to travel these huge distances in space to get there promptly. Hurry up warp speed science
Amazing shirt!
If planets simular to ours egsist , the life simular to ours does as well. But we all forget 1 thing thats important:"Life can be manefested in a lot of vais!!!" To us life is based on water and oxigen, but to some other spicies it could based on somthing else, like fire or even vacum, of some kind. Posibilities of life are endles, as for now we onli know this for, but what about the things we dont? Well there are a lot of them so if we would to try and search for them, I'm positive we would be amazed of what we would find!!! ;-) B-) :-)
There actually aren't to many possibilities for the materials that make up life. For us is carbon mostly, but it could be possible to have silicon based life. Its impossible to have have a life form be made of fire as fire is firstly not an element and secondly a combustion reaction.
Let me ask u some thing. What is the energy that keep's our body's form falling apart??? If u know that then u know what I was talking about. And there are a lot of things we don't know. Like for example whats smalar then 10th of a neutron? ;)
Naruto Uzumaki The force that keeps our body together is the electromagnetic attraction between molecules that form our body. There are a lot of things we don't know, but we do know that life cannot be formed from pure energy. Nothing is smaller than a tenth of a neutron, that is because our concept of 'smallness' breaks down at that point and the strong force between quarks dominate. Please keep your New Age Psudo-Science BS elsewhere.
Thanks for that I dislike when people spew opinions as if they where facts.
There is life in the Mariana trench at 11km depth, so life not only could but does exist at over 5 km deep in the ocean.
Thanx for this awsome show and interesting episode. Hope we find some life elsewhere in the universe soon.
Aliens, aliens everywhere
The only thing about the Gliese 667C b is that it has a phenomenon on it that is called the runnaway greenhouse gas effect. Meaning that greenhouse gasses can't be trapped underneath it's atmosphere, resulting in no liquid water. Sorry to burst your bubble.
rocking that facial hair brah , nice job
Problem with trying to guess the percentage of planets that could potentially support life is that we don't know about all the different kinds of life there could be. I remember hearing something about scientists theorizing that it could be possible that there are silicone based lifeforms. If I had to guess based off our current understanding of life, I would guess between 1-10% of planets could support earth-like life. As for how long until we discover life in any form (bacterial included) I don't have a time frame but instead two points in time. Either we'll find it on the Mars mission, or we'll find it once we complete warp drive and gain the ability to travel to other solar systems.
Christians be like:Life exists only on Earth,the universe is 6,000 years old,scienctists are sinners or God is just trolling us,i dont know....
The "I don't know" part kind of sums it up.
not all Christians are like that.
this is mostly just a subset known as YEC's, or "Young Earth Creationists".
many (or possibly most) people don't share the YEC mindset, even if otherwise religious.
Brendan Bohannon No but most of them are, and all it takes is most of them.
Brendan Bohannon i agree i am Christian and who KNOWS what a day is to God it might be 10000's of years
I believe some parts of Evolution is real.
I think about 20-40% of all planets in the galaxy have had life, have life, or will have life.
I don't think there is any way to predict when we will find interplanetary life. After all, the rate at which we are advancing is always fluctuating - it has gotten much faster in recent times, and how do we know we won't hit a roadblock again sometime soon?
.Infinity and maybe never. but still high hope that starwars and halo is real.
In an alternate reality
why would anyone want halo to be real?
advance in technology and new races among us.
Pretty exciting!
there are infinite planets with life because the universe goes on forever
Prove it. Yeah exactly lol!
Gilberto Miramontes prove that there is not infinitive planets, exactly...
LOL this dummy here! I'm not the one saying there's infinite planets :). Yup exactly!
LOL Steven, you can't be serious. there is NOT an unlimited number of planets in the universe. Kox is right, all matter in the universe is finite. I'm not going to explain myself further because I'm pretty sure you're trolling.
-“It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.” [Douglas Adams]
There is no way we are the only living thing in this galaxy yet alone this universe. I honestly think even though it sounds sci-fi and a bit mad to you boring folk that it's like Star Trek out there.
I really hope we find something on Europa.
*****
Please tell me you're joking
*****
I'm not sure there's intelligent life in some parts of Europe never mind bacterial...I mean look at France!!
*****
I'm gonna go cup half full on this one mate, we exist so I'm sure by the law of averages something else does too. Some of the basic building blocks of life can be found on asteroids along with ice, and we all know what happens when there's water. So far 100% of the planets we know for certain have liquid water on them have complex life.
Earth mate look it up!
This is so cool. I can't wait till the day we find life on another planet. It's so exciting.
I want that shirt...where can I get that shirt.
Interesting thought.
The question isn't whether there is life out there for me that is without a doubt that in the infiniteness of the universe at least one other planet could spontaneously generate life, the question for me is how on Earth will we get there. It would take us literally trillions of years to get to Alpha Centuari A (The closest star to Earth) with current technology and it is most likely that an Earth like planet would be even further away. Also considering that you cannot travel faster than the speed of light it would take us 1000s of years to develop the technology to travel there and even then it would take us hundreds of years to get there. So really I don't think there is much point of us considering the possibility of Alien life, or intelligent life.
I really think the term intelligent life is very vague as humans even 1000 years ago considered themselves intelligent so for all we know aliens are laughing at our idea that the Internet is advanced. So really I think the prospect of humans and intelligent aliens ever coexisting will not happen simply because of the logistical side of things unless it were possible to travel faster than the speed of light.
If it wasn't for the Dark Age minded, science hating, warmongering abrahamic religions, we could very well be "Star-Trekking" by now. Imagine if only half of the funds allocated to the war machine was put into actual scientific exploration.
look up on youtube the documentary Evacuate Earth Escape from a Neutron Star (think its called that pretty sure) it shows how we could travel to another planet even though the trip is 80 years and the had 75 years to build the ship was built to harbor a million people so ya if we had the money and determination we could :)
Dyvim Tvar
yes, but Star Trek tech is a type 2 technology, meaning they can harness the power of their mother star for energy. We humans are type 0, we get our energy from dead plants and animals, fossil fuels. And it will take a few centuries to make it to type 1, controlling the power of the planet. We have a loooong way to go.
VinceLovesToast I have seen it actually, but realistically speaking that is not going to happen and I am not sure if our technology could advance by so much so quickly and that was on a planet that was relatively close to ours in reality we will most likely have to travel much further.
Scott Andrew True but for me the problem is not just conquering speed, it is working out how humans can be safe at such speeds because we would be going so fast at even half the speed of light that it would kill us due to G-Forces. I know we seem to be a long way away from developing type 2 technology but the fact is humans are advancing rapidly so it could be researched much quicker. In 80 years (the average lifespan today in the UK) we went from using horses and carriages to sending man on the moon so you never know how different things could be 80 years from now.
Love the shirt!
Turns out 100% of those billions are too far away and too dangerous to get to. So no matter how much like earth they are we're stuck here. However, if we tax the religious and use that money to invest in space stuff maybe we could do it. Just tell them we found a space gate to their particular version of the after life and the tithing will pour in.
Hey, be careful with that fedora. You might poke someones eye out,
What? Sorry I don't get you esoteric reply. Should I be amused or insulted? Well 3 people got it so good for you. Moreover, my hat collection is none of your business.
I think you should take it as a compliment.
The reasons that researchers decided to expand the Goldilocks Zone were more complicated then you described, right? I was just chuckling at the idea of scientists realizing that they forgot about clouds and quickly changed their numbers.
WE ARE ALONE or shall i say where is the evidence no one talks to us its kinda depressing with all these high estimates yet no single fuck is given by the rest of milkway ffs i just want to meet one intelligent species from another planet and i will die a happy man even though i might freak out upon seeing them for the first time. and no one cares about microbial life
Our universe is fairly new so finding intelligent life out there is a pretty hard thing to do right now. Don't get your hopes up because of all of the sci-fi movies you have been watching.
O my lord what a video!
hi
hi
Andrew hi
the key to finding this and pushing our technology to its limits for further research and missions is a more scientifically inclined mind state for everybody, we need everyone's support and willingness to invest

Yeah it would have to at least be slightly more than 0% because Earth has to be included in there.
You can't be serious?
omg that shirt i was too distracted from his shirt!
I know, right? Anthony's shirts are so awesome.
I always sit here and think that someone from another planet could be doing the same thing I am and it always gets me excited. But I know that I probably won't be alive long enough to see us travel to different planets and find life.
I predict we'll be hearing something about it in year 2020
Loving the shirt ant.
I love your shirt!
If Life isn't synonymous with being carbon-based, then even MORE bigger than before.
If you want a percentage, then maybe 55%?
The real question being ofcourse, what qualifies as "life"? And just like that, from the tree of one question abounds countless number of science fictions! :D
I always liked this definition: Life is the property of being able to evolve by natural selection. I know it's not perfect but i still like it.

If that be the case, then isn't the whole Universe itself, alive?You know, as the Universe evolves where the most stable atoms/particles/gas clouds win over the ones which were unstable? And the unstable ones either fizzle out as energy and multiple breakdown products or itself transmutates into another element/change it's order to form a gas cloud/star/planet/asteroid? :O
Bascially a constant adaptation process to adapt very well to it's environment.
Alonso Quintero, I guess the Universe is a more understandable creature than it's smaller constituents. For example, a woman. :P
Since it takes something like 70 thousand years to reach the next star system I think finding intelligent life is out the realm of possibilities right now until we find a faster we to space travel, which I doubt very much will happen in my life time.
That said, I think there's an extreme possibility that we could find microbial life in our solar system if we are able to land & explore planets that we know could potentially support life like Mars or Europa (not a planet, but I'm sticking with that example)
Ok Trace, I have a question. Could you tell us, what would actually happen if we find life on another planet, that is like 30 light years away? What would we do? Like would we send a probe on that planet, even if it that far away?
Trace wasn't in this video. Anthony was, but not Trace...
***** Yeah but if intelligent life would be there, we would have to consider the fact that they might be hostile... I mean we wouldn't just recklessly message them "Hello!!!", you know what I mean. I was asking if they have like prepaired procedure, what to do or who to inform when they find extra terrestrial life. Tartar Shoes, thanks for telling me this. I didn't really pay attention when I was writing this. Thank you!

Sending a message to a planet 30+ light years away would be impractical. I mean, they would probably do it regardless assuming they had the capability, but you have to remember how long it would take to actually get there. If you were sending it by radio waves, by the time our message got to the planet 30 light years away the guys who sent that message would be long dead.
Sending a probe with current technology would be pretty much impossible.
We can find all lives in the universe within a lifetime. Using atomic powered spaceships we can reach 99% the speed of light. We can build such ships at a constant rate. But each ship would travel to the nearby star and create a factory that will build more ships. This would mean that very quickly we can cover the entire known universe. And all of this would actually be very inexpensive.
Well considering that our universe is practically ever expanding at a speed faster than that of the speed of light and considering the fact that there are more galaxies than the amount of all life on earth summed up together into one number and also considering that each galaxy has 60 billion planets that can sustain life, then I think that about at least 2% of all of the planets in the universe have life, which is still a pretty large number.
my opinion: less than 1% support life
when will we find it? never, we'll either destroy ourselves, die off by other means, or we'll realize that it's impossible to travel interstellar no matter the tech, and give up on it.
Do you think 1000 years ago, when people looked up at the tiny glimmer of light that the planet Mars is in our night sky, that they could ever have imagined a human made object would be roaming round it taking samples and sending photos back to Earth for us to see? 1000 years ago that idea would've been beyond comprehension. Who's to say what we will see or do in the next 1000 years!
I get into arguments about this one all the time with people, and I was just wondering if anyone out there could tell me if this doesn't make sense: Statistically speaking, there is no other planet with life, considering that Earth is the only statistic we have. However in probability we could assume that at least 1 in every 8 planets has life, considering that our planet is that 1 out of the 8 in our solar system.
Haven't we already talked about this?
The number of possible planets that could support life in the universe could be infinity if the universe keeps expanding and creating new planets...etc. I think we will discover new life when we have better telescopes or when we can send people to one of those planets within a reasonable time.
Hey Anthony! Do you do the narrating for Nature Hates You?
I believe life is possible anywhere.We have yet to discover these life forms though
I'm positive that there has been, is, or will be other life in the universe. The problem is, the universe is so vast and so old that we will either not exist at the same time in a close enough distance to meet, or any intelligence we meet will be vastly inferior or vastly superior.
Another thing to consider is that if we're talking about intelligent life, then technology could allow such life to live on a planet that would not have been habitable without technology. Those seemingly uninhabited planets could be home to non-native colonists living inside bubble domes.
I don't think we'll ever find a planet with life because of how far away we'll have to travel to get there.
Oh my god! STAR TREK IS HAPPENING! YAAAAAAAAAAAAAAYYY!
That's an exciting idea. I don't think that we'll find life in my lifetime, but I'm hoping that will happen within my children's lifetime.
Aren't there organisms living in a red water fall that breath iron? It may be a lot more possible for live to exist than we know.
I don't even remember how i got started into DNews but i don't regret it...also he always has the best shirts
I would like to see Dnews videos in 1080p or better.
