The distance separating us from Proxima Centauri, the closest star to Earth, is 266,000 times greater than the distance separating us from the Sun, and 103 million times greater than the distance we had to travel to conquer the Moon. IN this video we will talk about stars colonization.
Impressive, isn't it? Could we colonize stars?
Space colonization has always been a fascinating dream to realize.
Even a ray of light, moving at the maximum speed allowed by the laws of physics, takes 4.3 years to reach us from Proxima, while less than 8 and a half minutes are enough to fill the space that separates us from the Sun.
In these numbers, in their relentless inevitability, is enclosed the problem of interstellar travel.
If we take into account the size of our Galaxy (about 100.000 light-years diameter) and the size of the observable Universe (more than 12 billion light-years), considering the question of the trips in the cosmos can only leave us a deep sense of inadequacy.

"We will never travel among the stars based on current scientific understanding and technology" would be a more honest title.
I don't think you fully understood the video. It's not about technology, it's about physics. Even IF you could travel 90% the speed of light, it still wouldn't be possible. Do you even understand physics well enough? The only thing that would make this possible is the be able to travel much faster than the speed of light and not even doing it by travelling through the medium of interstellar space. Technology? Basically what you want is faster than light travel and you'd have to be an idiot to say such a thing is possible. No "worm holes" are not a thing, they are purely theoretical.
Not completely. We can do it with Newtonian physics. We need fusion power though but we can see that's happening in the sun so that isn't a theoretical possibility it's real.
Yeah. Title is just click bait.
Physics dont change. Rules of the universe don't change.
That's a lot more optimistic! 👍
I have a feeling there’s physics in the universe that humans haven’t even began to discover.
Some may have and keeping it secret from the rest.
This is true the govt know about zero point energy but it’s not in the media because it breaks our current understanding of physics
Amen
Just think about how much the government isn't telling us
@@arnolddooley5919 No one will ever be able to tell you what they themselves fail to understand..

physics didn't provide fundamental barriers to this.
Too much of you can do whatever you want
@@MrGottaQuestion what physics are you referring to? With computer technology and hibernation, we could travel to the nearest stars. The question is how safe we need it to be.
Physics absolutely doesn't hinder us here. It just takes time.
Building large enough ships we could slowly accelerate a ship to a fraction of light speed and then start deceleration half way there. Getting to the nearest star could probably be done in a century or so.
There is no fundamental physics barrier about space travel, what so ever. If there were, the universe wouldn't be teeming with solar systems and galaxies like it is.
The video straight up conflates "interstellar travel" with "I took a trip to Proxima Centauri last spring". That is not what anyone mean by interstellar travel.
FINALLY , someone had the balls to say it and back it up with science !!!!! If we as humans continue to in fight over ideologies and political leanings. we sure as hell aren't exploring space anytime soon.
It's not about people our children AI computers will.
The financial and scientific efforts needed to travel to other solar systems is better spent on saving Earth from the human effects on climate, pollution, over-population and social conflicts.

Fantastic answer 😉
When first we crossed the ocean we did it in small wooden boats, then we learned to make bigger strong boats that were powered by wind and carried more people and we found steam power and then even bigger ships of iron and steal and now we dont even need ship as we can fly accross the oceans in a few hours anytime we choose in planes...
Nothing is impossible for ever... thats what makes humans great!
However, we do have our limits
Humans do noting. Humans had to wait for Prometheus to discover FIRE.
Humans have to wait for a god to bring us to the speed of light.
You are failing to take into account the distances involved here........believe it or not, no matter how great you think humans are,........the universe is REALLY BIG........and human beings are REALLY SMALL.........twenty thousand years from now, someone or something will examine our historical record and say.........can you believe that once upon a time, a large number of seemingly intelligent beings, actually elected DONALD TRUMP to be their leader.....?????????????
@@davidglemboski258 I cant deny humans of our time are small minded and limited.... yet compared to those who lived 15,000 years ago we are clise to gods... maybe it will take another 15,000 years before we have grown enough to take that next big step but we will take it, if we don't wipe ourselves out first!
I mean I get it to have low expectations especially with current technology and political issues. I mean survival’s sake the planet will face resource limits then we might explore space or other solutions to accommodate those resources. After that then new tools and technology will be made or discovered to be faster like cpu chips to reach the stars or whatever.
A 10% C speed would allow a trip to Alpha Centauri in just 43 years. Question is, how well do we understand the density of interstellar debris?
that's right it's not just about speed, everything human build that we use in all aspect of our daily lives are not designed to last more than few years. This is what those scienfiction films always fail to address. You can invent some kind of hibernation for 200 years to get to the next habitable planet on a spaceship. But that spaceship cannot take a break, it is working hard everyday to stay functional. So far no human technology can make simple computer, power supply, circuitry that can last even decades without total replacement. Just look at the ISS, or any any human made space object now, without constant maintenance they all break down completely in just few years or months even.
I never say never, but right now its impossible to travel to another star, imagine hitting a small rock at the speed of light
That would be 10% average. To get the average, you need to accelerate well past the average, then decelerate at the other end (assuming you want to stop to have a look around). Accelerating a mass requires energy, and the mass increases with velocity. An enormous amount of energy is required to get there in a hurry.
Remember that time goes slower the faster you move, according to Einstein. So it may be possible that it is 43 years, for the dude in the shuttle it isnt.
@@kamikazekrush3758 A grain of sand at the speed of light would wreck a spacecraft. At that speed even individual hydrogen atoms in interstellar space becomes an issue.
My grandma just passed at 95. She told me jets used to be in books and people would scoff at the absurdity of travelling at the speed of sound. It we make it, say 1,000 more years who knows.
Way less than that I’d say. By 2100 we will be in S
we cannot travel at the speed of light because we are made out of mass
@@alen380 what if you were able to harness enough energy to create some type of magnetic field, creating a pocket inside an anomaly that is used for travel?.
You know how a dolphin rides the wake of ships. Right in the pocket, an eddy if you will. Can we generate something that folds space like the bow of a ship and ride the pocket as well?
@@praxis6172 I guess that what you are saying is related to a future IV or V type civilisation and it is probable in a distant future, we humans have made a huge step forward in technology in the past 100 years so I could agree with your argument, but still by the time humans do that both you and me will be long gone hehe
There‘s a small mistake when the number for the speed of light is mentioned the first time. It is not 299 million km per second but 299 thousand km per second (or 299 million meters!) Very good video!
found it too and its not small its 1k fold mistake as the number is in m not km
We never thought we could fly, we never thought we'd break the sound barrier, but we did, I'm sure, if it's at all possible we will find out 😊
Flying, just as flying really fast don't violate the laws of physics. We are never going interstellar, not as organic beings. Unless our consciousness can be transferred to synthetic bodies, we as a species are doomed to stay right where we are.
the frustrating thing about lightning speed is that it is still frustratingly slow compared to the size of our galaxy or others, if we attained the possibility to travel at lightning speed we would still be like a snail trying to travel around the earth's circumference
lol. I’m afraid it would be a lot worse than that. The snail would slither a thousand circles around the world before we made even one light speed trip around the Milky Way.
for starters we could very well settle for something like 0,3 of the speed of light .
more than 10 stars are within 10,5 ly away from us .
which means it would be possible to make a trip to them .
trip to alpha centauri would only take circa 14 years at 0,3 speed of light .
and engines 0,1-0,3 of the speed of light are already debatable (or at least possible in theory) .
we don´t need to colonize the entire galaxy any time soon , we just need to build good enough engine to get us out of this rock and to colonize
at least closest star system , that way we don´t end up being wiped out by a single catastrophic event .
from there we can further develop our technology ,
we will have literally hundreds of thousands of years to improve once we are no longer just a one planet species .
you have to temporarily change dimensions....the 'material' world
does not behave like the higher dimensions....
@@tracedog27 Yes, you are right, but you have to consider time dilation. When you travel at the speed of light, time seems to stop from your perspective. So, if you want to go to Alpha Centauri, which is around 4.3 light-years away, the trip would only take a few days from your point of view as a traveler
Lightning speed is actually slower than the speed of light. But it is true, the Milky Way is about 180,000 light years across.
Doesn't this also make it unlikely that any aliens will ever visit us?
according to guy who made the video yes.
But I would say, probably everybody is expanding their reach, at 99.999999% the speed of light, but they're taking it slow.
A combination of that and SETI is simply not sensitive enough to draw any conclusions yet.
They would have to be able to pick up accidental signals such as weather radar on another planet.
The most probable aliens would be some kind of quantum robots, not any naturally evolved being. And both unlikely
"Doesn't this also make it unlikely that any aliens will ever visit us?"
About 11 million aliens have visited the United States and most of them are still here.
Not Aliens, but Alien AI or hybrid Aliens. It's a question of time until we become hybrid beings with a bunch of artificial organs in our bodies that will expand our life expectancy and intelligence.
aim for 1 to 10% speed of light combined with posthuman cyborg bodies that don't age. it would take 40+ years to reach nearest star, but if you're immortal, this time is a blip. this seems like the most viable option for interstellar travel imo.
In order for you to retain self, your brain would have to be included in that cyborg, and it still ages. Transferring information from your brain does not transfer you, just a copy of you.
We've got millions of years to find out if there might be feasible ways of colonizing other star systems.
Maybe by harbessing fusion reactors?
The technology required for interstellar travel is probably metaphysical.
That's a contradiction in terms.
True :)
@@johnhitz1185 No, there is Physics and there is Metaphysics and no, Metaphysics is not about "feelings" XD
UFO literature seem to point to use of magnetic fields for propulsion and an ability to manipulate space and time to travel at high speeds. Maybe this is something worth exploring.
I am aware of how often in history someone has said that a given event, situation, etc. was impossible. Further, I will admit that it appears, by what you have said, that interstellar travel at a reasonable rate is impossible. That being said I firmly believe that time will prove you wrong and that we or someone else will indeed travel between the stars.

No offense but you simply don’t understand. Humans mastered the manipulation of basic physical materials and chemical reactions many thousands of years ago. Today’s tech is no more than minutia of the same physical contortions. For us to master near light speed travel is the equivalent of a fetus learning Mandarin while still in the womb.

There was a lot of people who said we'd never be able to fly either, we've made it so far in the last 120 years, it's insane to think we'll never leave our rock lol
Actually, no one ever said that. From day one, man has watched birds fly.
@@jamessullivan4391 People, not birds, learn to read, and yes plenty of people said that, infact a journalist in new York times wrote just weeks before the Wrightbrothers actually managed to fly that man would never fly, atleast not for between 1 to 10 million years.
@@wiseomg Did you ever see Planet of the Apes? Charlton Heston proved flight to the apes by making a paper airplane and throwing it. Do you honestly think people of a thousand years ago and even 10,000 years ago didn’t simply understand the intuitive physics of watching insects a birds and realized that your lift potential from wings, let’s say, plus speed must compete against your weight or gravity? Shit, I was five years old and tried it with “home made” wings and realized I was just too damn heavy. But I understood at that tender age that there was no barrier or law of physics preventing me or animals around me were doing it. It was just a flaw in my design. I needed counteracting energy to the force of gravity. You cannot honestly believe a journalist who wrote an article once and assume the great thinkers of Ancient Rome, China, India, Egypt or Greece didn’t contemplate how to overcome the struggles while arrows and rocks were slinging everywhere in warfare and motherfucking birds were doing it too. It was only a question of engineering. So the ancients figured out Pyramids, aqueducts, gunpowder, geometry and that the earth is not flat but no, no flight is obviously not possible. Pythagorus and Euclid could not conceive of such a thing.Hot air put into a confined space, like a ballon delivers lift and sufficient force to counteract gravity. I once heard from a journalist that I need to wear two masks while driving in my car alone to protect me from CoVid. Uh… okay. I would go with science and simply say that flight was never defying the laws of physics, like saying going beyond the speed of light/causality, and was a simple matter of achieving the engineering skills to produce it. Read “the Flight of Icarus” in Ancient Greek mythology and see that a boy with feathers held together by wax, but he flew to close to the Sun and they melted, is an achievement of understanding that “we simply cannot do it yet,” not that it is impossible unless you hold religious views that somehow banned it. My own faith never “banned” it. So to close, just use a little common sense here.
@@jamessullivan4391 You said "Actually, no one ever said that. From day one, man has watched birds fly." That mankind trough the ages watched birds fly have nothing to do with the comment you were first answering, wich was There was a lot of people who said we (mankind) would never be able to fly and they ofc were wrong, i even pointed out a spesific "brainiac from the new york times saying this in 1903 only a few weeks before the Wright brothers made the first flight, look it up.
Ahh, okay. Got it now. Mispellings and wrong prognostications have lead me to believe that you don't know shit. No offense, I have to leave this thread to argue with smarter people. Take care.
This just means you can't make the well connected galactic empires you see in a lot of sci fi. It doesn't mean groups of us can't just move through the universe slowly.
rimworld
Nah, it is possible to travel trough universe very fast says psyhics we know today....and what about physics of tommorow.
@@kvarnerinfoTV Yes, Alcubierre demonstrated there's nothing preventing the warping of space to achieve faster-than-light travel. The problem is the energy required to do it would be something on the order of what you'd get from a black hole. So, until we're able to create artificial black holes, harness their energy, and use them to power an Alcubierre Drive, we're not going anywhere; or at least not going anywhere very quickly.
If we're serious about colonizing distant worlds outside our solar system in the near-term, it's going to have to rely on generation ships or some form of cryosleep / hibernation / suspended animation.
@@JohnDoe-zl6qw energy requirements for a alcubierre drive are being smallaer and snaller with every new paper. I am quite positive that in next few decades we will be able to lower it to acceptable levels.
Also we will soon have tech to reach near light speeds so closest stars will be far closer...
@@kvarnerinfoTV The power requirements may be decreasing, but reading deeper you come to realize the power requirements are still (A) astronomical relative to what we can produce today and (B) rely on something that is currently being called "negative energy".
With regard to (A) the original calculations called for a ball of antimatter the size of Jupiter to power the Alcubierre Drive. That's since been revised down to one the size of the Voyager 1 spacecraft. Sounds reasonable, right? Until you realize the only anti-matter we've been able to create has been in particle accelerators/colliders. In 2010 the Large Hadron Collider created a total of 38 anti-hydrogen atoms worth which lasted 0.166 seconds. More has been produced since, but still in equally infinitesimally tiny quantities. We're a long way off from producing tons of anti-matter that will remain stable, let alone that could be safely stored and transported to be used aboard a starship.
Also, there's no such thing as a free lunch. It takes energy to power a particle accelerator/collider. You don't get to create energy out of nothing using such a device. The energy you wish to store in anti-matter has to be energy you put into the accelerator/collider. The amount of energy stored in a Voyager 1-sized ball of anti-matter exceeds the total energy output of the entire human race the world over at current production levels. So what do you propose? We all stop using electricity and burning coal, natural gas, and oil for a year so a theoretical warp drive can have enough fuel for a test flight?
Then there's the economic burden. It's estimated 1 gram of anti-matter has been produced in total by all experiments to date that have attempted to do so...at a cost of one trillion dollars. At a launch weight of 1,797 lbs, a Voyager 1-sized ball of anti-matter would cost $815,105,542,800,000,000 (that's 815 _quadrillion_ dollars). Where's that money coming from?
With regard to (B), we have no direct evidence for "negative energy" yet. It may not even exist. Alternately, it may turn out to have ties to Dark Energy or Zero-Point Energy. Regardless, we're still a long way off from even being to able to construct an experiment to witness it let alone harness it (if it even exists).
I'm not against the advancement of scientific knowledge and technology and would very much like to see us achieve some form of propulsion to take us to the stars. However, dreams must be grounded in reality if you ever want to achieve them. There's far too much dreaming and not enough grounding when it comes to these discussions, with a flippant disregard for the overwhelming technical, engineering, social, and political challenges it presents.
We are not even remotely close to being able to build a working Alcubierre Drive in our lifetimes. I'm not saying don't pursue it; I'm simply cautioning one needs temper their expectations and to be more realistic with regard to the timelines involved.
More importantly, I think the mental, psychological & physiological effects of such longterm space travel required to goto those stars, are probably VASTLY underestimated. High risk of mental insanity.

Its not just about getting up to speed and the risk of possibly hitting something its also about trying to stop once you get there. You cant just stop in space going that fast.
Just build the spacecraft like a rocket with several rotating deflectors and pulverizers at the front. The diameter of the cylindrical spacecraft should be as small as possible.

I trust you are not elderly.
My son and I watched War of the Worlds, and he asked me if I am worried that aliens could attack us. I said no because the distances to the closest star is impossible to travel. We watched your video and he is now convinced that an alien invasion will never happen.
As they say, “never say never” because you never know!
Given what we’ve learned in the last hundred years or two, and that things are accelerating, imagine (if we manage not to blow up the planet to oblivion) what currently unimaginable things we might have discovered in the next hundred years or two. This video is perfectly sensible, but it should add “in the current state of our knowledge”. Who, in 1850, could have imagined the Internet or the GPS? Not even Jules Verne did.
Also, who says we need to explore the galaxies with our very inadequte biological bodies? Maybe that will happen only once we’ve transformed ourselves into some kind of electromagnetic entity or uploaded ourselves into one? There are probably more surprises lying in wait for us than we have ever experienced in our past history. Hopefully not total self-obliteration though…
Never say you never know because you never know never.
Tell me something: If we do an experiment today to measure the weight of a cubic meter of iron and the experiment tells us that a cubic meter of iron weighs 7,873 kilograms, do you think that in the future a new theory of physis will be developed such that when we weigh a cubic meter of iron suddenly it weighs 20,000 kilograms instead of 7,873 kilograms?
There are many possibilities, of course. But the video is making a general statement based on the likelihood of those things happening before we are obliterated by either ourselves, a virus or local catastrophe, or some outside force like a meteor is quite low.
@@icadoriogorgeousiano9454 The weight of objects change according to which planet they're on. Thats old news bro.
I think, that the main problem is the definition of "we". If we widen it to our creations like robots and AI, maybe even our minds recreated as AI, then all those arguments are not applicable. 400 years at 0,1% c to Proxima? For an artificial intelligence it is absolutely no problem. For a digitalised human mind it could be Star-Trek or Star Wars or whatever experience it chooses. All you need to do is to change the time perception. With years passing like secunds, it would be just a five minute trip (I would rather choose an hour as a year to have a chance to read some book and explore my virtual Millenium Falcon at least ;)
Just because we currently don't know how to visit other stars, doesn't mean there isn't a way to do it. It simply means that WE DON'T KNOW of a way to do it. Humans are constantly learning, and given a little time we will figure out a way.
We know nothing. We only know about 5% of what there is to know. Dark Matter (22%) and Dark Energy (71.4%) surround us, yet we have no idea what they are. We SO don't know that we just call whatever it is, "dark." Maybe we just need some more time to learn as we're just infants yet...
I agree. Give us a problem to solve and we will. This entire video assumes that we will not advance any more than we have to date. That is wrong.

We could colonized other star system if NASA had the budget of U.S Military.
We won't, future descendants will.
The dilemma that has always confounded me when I think about space travel is one of simple
Geography. The information we have (ie, what we see) is old information. The light from astronomical sources we see is old (as much as thousands or millions of years in some instances). Those objects have moved in that time (the galaxy is rotating and space itself is expanding). Flying to Vega, for example, is not like flying to Vegas. Because Vegas is always in the same location. The best we know about Vega is where it was located 25 years ago. Although Vega is “close” and unlikely to have moved much “galactally” in 25 years, the problem is much worse for more distant stars, let alone locations outside our own galaxy. Also, we all know stars go through phases, one of which includes a supernova. Given we are always acting on old info, it is entirely possible we could chart a course to “Star Z” only to find Star Z has exploded in the hundred or thousands of years it took its light to reach us when we charted the voyage. Creating reliable and “dynamic” maps that adjust for historical movement of objects and future movement (during the time it takes to make the journey) strikes me as a daunting proposition in and of itself.
Vegas has moved just as much as Vega. The bigger problem is knowing where you will be.
Trajectory to Mars and other astronomical objects is planned based on its location in its orbit around the Sun by the time we get to the destination. It is possible to predict the movement of nearest stars in respect to our own or in respect to the centre of the galaxy, so it should be possible to chart a course, accurately predicting its location by the time we arrive. Even working with old info, we should be able to predict the current state of the star in the present VS. the apparent (X ly in past). Unless there are clear signs of a star going supernova or it being on the other side of the galaxy, 1000 or even 10 000 years is just a blip on astronomical scales so it is unlikely for a star to disappear in that time.
@@ilmarssalna8900 Uh, the light from Mars reaches us in 2 MINUTES.....Yes, we can account for that and predict where it is going to be. You could probably even make assumptions about things with 100s or 1000s of light years away. But You cannot know with any reliability where something is going to be or even if it exists if that light is BILLIONS OF YEARS OLD...
Motions of stars can be predicted just as the motions of the objects in our solar system, assuming you're trying to reach a reasonably close star. If your destination is so far that you're worried your target star having gone supernova by the time you arrive I'd say you've got other problems. :')
Conveniently the same laws of physics preventing you from observing the "present" state of a distant object will prevent you from reaching it...
Probes. We would send probes to cut that useless flight out of the equation if traveling faster than light were possible.
That's a bold statement, but I have to agree it is a remote possibility. To date, moving any mass beyond the speed of light is impossible. Even accelerating to 1/2 the speed of light would kill everyone on board. Even at 0.1C it would take 40 years to get to the nearest star. The whole "folding space" thing is just hypothesis. Gravity can bend space but even if we could build some kind of gravity generator the power required would dwarf the current global output.
If it took 40 years to reach the nearest star, and we sent colonists to the Proxima Centauri system in 2050, then we'd have humans living in another solar system by 2090. That's... not very long compared to the length of human history.
@@adammclaughlin845 While there's without doubt a sheer infinite number of Earth-like planets or moons sprinkled allover the observable part of the universe, the chances that one of those happens to orbit around one of the closest 1000 stars is probably quite small.. and almost certainly there's none in the A Centauri system. So this would most likely be a very educational one-way trip much better done with unmanned robotic probes. (Not even talking about the energy/propellant problem, sufficient means of life support, high energetic cosmic radiation and collisions with cosmic molecules/dust/micrometeorites...)
Not a remote possibility, but the most likely scenario (says someone who studied astrophysics). It's not just not possible to move any mass beyond the speed of light "to date", we have not observe this happening ever, even in the most energetic cosmic particle accelerators observed (active galactic nuclei, GRBs, supernovae), and if it were possible at all you'd think that those objects, which output energies a trillion times higher than the largest particle accelerators on Earth, would be able to do it. Even completely massless particles such as photons (eg. light) travel only with "c", not faster. So if it were possible to somehow exceed this fundamental speed limit, it's not something that could be achieved with the help of any of the known types of matter or force fields - and if there are particles that indeed do move faster than 'c', they have yet to be found, and guess what - your or my protons/neutrons/electrons etc forming carbon, oxygen, hydrogen etc. atoms of organic or inorganic matter as we know it are definitely not among them...
Physicist Miguel Alcubierre proved that mathematically, warp drive is possible.
@@richfrazier8756 Alright, it's mathematically possible. And how much energy do we need to do that ? Is it even a conceivable amount ?

In the 1840s just as the first tracks of the Continental railroad were being laid down, "scientific authorities" swore that trains would never travel up to sixty miles per hour because that velocity was fatal to a human being. A few decades later a celebrated scientist wrote that everything that could be discovered in the realm of physics had already been discovered and now scientists needed only to concern themselves with the proper interpretation of the data. Right...
...without artificial gravitation and various shielding against cosmic rays and other particles, interstellar travel is impossible...
And what about Astral Projection?
Who cares
@@Heart2HeartBooks Sounds like "whataboutism", so who cares?
Artificial gravity is easy, you just get a large cylinder and spin it, and shielding is pretty easy too, we can already shield against everything that we need to, it's just expensive in mass to get all that shielding on things that need to be launched off earth
My grandfather was born in 1900. He went from an era with the horse and buggy to us landing on the moon within his lifetime. To say we will never achieve the things that are impossible today is assuming we have attained all of the knowledge that is attainable already.
The problem is with human evolutionary nature and mortality, we will kill ourselves before we will have the technology to travel interstellar. It's just all hypothesis and fantasies. That's why we have no solid proof of aliens visiting us from another star system. All species will kill themselves or exhaust all their resources before they can get advanced enough to defy their evolutionary biology that bounds them to their local system. The universe don't care about our dreams and fantasies. Millions of species has died out before us, we are not that special just because we evolved higher brain power. Comparing horse buggies to man on the moon is not in the same ball park.
We can achieve that easily within the laws of physics. Interstellar space travel requires new knowledge and technology that that pushes the laws of physics to its limit and the most important thing, our biology to survive such travel.
If I'm a betting man, I would wager that mankind will extinct ourselves waaaay before we can survive interstellar travel.
Your grandfather could just wait for new technology, as you see today. But time travel or travel beyond the galaxies is another matter of fact. There are physics laws you are no able to break. This video is talking about that. Not just technology as you mention.
I won't refute you, but I'll respond with a quote from my physics professor back in college:
A “law of physics” is merely our best guess so far of how things really work. They get broken all the time; that is, in fact, the only way physics progresses: by refutation of conjectures. Conjectures that survive lots of careful attempts at refutation achieve general acceptance and are often confused with “truth”, but they are always provisional, and we assume they will eventually fail in some context.
@@gstcomputing65 You're right but so many time people has trying to break Relativity and still we are under their rules.
I've got news for you, every single thing that was impossible in 1900 is still impossible, and everything that is impossible today will be impossible in another hundred years. There is a difference between IMPOSSIBLE today and INFEASIBLE today. But there really are things that are impossible. And those things will never be done.
Albert Einstein came up with the theory of warping space. The ability to bend space to make 2 objects closer. No need to travel for light years when you can effectively join 2 points that are light years away.
People hating on the title just have seen too many sci-fi movies. Interstellar travel involves navigating through absurdly long distances in the most hostile environment possible for longer than modern human societies have existed. Human lifespans are just not designed for space travel, maybe if we merged with machines and became androids we would have better chances, but that still does not solves the feasibility problem. Terraforming a planet is not a walk in the park, and everyone here just mentions it as if it was an easy task with 100% success rate that could be done in an afternoon and not in 100k years.
In a way, it's comforting to know that we'll be safe from malicious aliens who might show up at our doorstep one day. On the other hand, knowing that there most certainly is other intelligent life out there but we'll never meet due to the vast distances involved, is quite sad.
How do YOU know that? We could have aliens living amongst us right now. think about a civilization out there somewhere that has a BILLION years of evolution on us. Do you actually think they are as STUPID as we are? Yeah we really haven't been around for very long at all... not compared to cosmic time. Also think about the odds of us as a civilization living at the SAME TIME as another civilization located wherever. The odds of multiple civilizations LIVING AT THE SAME TIME is really tiny. Sure. think we'll be around in a million years? and remember a million years is but a drop in the bucket compared to cosmic time. yeah Earth has been here what, about 4.5B years.. well that's 4,500 M years!
The ones that meet will be really lucky, maybe two habitable planets in one system.

So especially at a time when our actual government has confirmed recording uap objects breaking the laws of physics lol not saying they are aliens, just saying they are literally recording objects breaking the laws of physics as we know them in multiple independent systems at the same time.

I like what your saying and I agree. Right now these are barriers we cannot break and in time I'm almost certain we will. And when we do it will be a long time before we realize it worked meaning interstellar travel. We will naturally not start our anywhere near a tenth of speed of light and even at the speed of light from our prospective hear on earth well we'll not know if the trip worked until whatever agreed upon distance in the test. Either way for the folks back here on earth will need patience
Advancements in relationship to time have compounding effects. Meaning the time it takes us to make great discoveries not only shortens but as the frequency of discoveries increase so does how impactful the discoveries themselves are. What we make advancements on in 10 years will dwarf the previous 50. The next 50,000 years will make the previous 50,000 seem like nothing. Imagine bringing just a simple mirror back 50,000 years ago lol.
Ok hear me out. Let's say 1000 years ago someone says, "Hey you know what? Traveling at the speed of sound it's impossible, even if you find enough horses to do so, you will end up that traveling that fast can make you crash with only one little stone on the ground", while some guys 1000 years later be like, dude you are thinking horse is the only way of travel.

I came to the same conclusion years ago that its all a pipe dream and went to bed depressed realising I would never ever leave this world, never see anything of this universe and it seemed really unfair and wrong, then I had a dream, I 'woke up' and found myself floating in deep space watching the earth slowly recede in the distance, I was not alarmed or bothered as in a dream when an old raggedy clothed wild haired man appeared, looked like an Indian mystic or Tibetan type sitting cross legged and he had a black stone like obsidian on his forehead, he looked really annoyed and miffed and his very deeply wrinkled face looked like it was scowling and he grimaced and said " It takes 86 hours to travel the universe" nothing more and then he disappeared to a point of light and I woke up, hell of a dream but it got me thinking perhaps there is more to this game than meets the eye. wish he had of said how.. lol.

I found it helpful to actually do the calculations myself. Consider a light year to be 5.88 trillion miles away, (Alpha Centauri is 4.27 light years away), divide by the speed you’ll be traveling at, in this case 38,000 mph, divide by 24, then divide by 365.25 and you’ll get 75.37 thousand years. The calculations approaching light speed is beyond my grasp, so I’ll take your word for it. Still, I’m quite amazed at the number of people who want to affirm the possibility of traveling to Alpha Centauri. I think this is quite common, though it flys in the face of math and science. Of course we the living will never know for certain if this is actually a possibility, but I find it strange that there is no sense of human limitations here. And then I strongly question why we would even want to venture this far when our real concerns should be here on earth. I’m wondering if there is an inverse relationship between faith in technology vs faith in our humanity to address the problems we have here. In other words, are we inordinately caught up in the possibility of space travel that we would choose to abandon our responsibilities here on earth?

And this is why no aliens are or have ever visited Earth. Since there are no other planets in our solar system that have intelligent life capable of space flight, they'd have to come from distant stars, which is quite unlikely due to the vast distances and time required. Physics didn't prevent us from being able to fly in an airplane in 1900, technology did. There was no physical reason why we couldn't fly if we had the proper engine and construction technique. Physics, however, does prevent anyone from traveling anywhere near, and certainly not faster than, the speed of light. Doesn't matter what kind of technological advances are made in thousands or hundreds of thousands of years, we still will be limited by the speed of light.
Honestly I would be perfectly content with visiting the Moon and colonizing Venus. I once did an original sci fi story about a man who worked with thousands of other people to terraform Venus. However instead of making Venus the same as Earth they instead created an entirely unique environment and biosphere that humans could adapt to over time. If I could be a part of something like that it would be a dream come true.
When the Russian space agency sent a probe to Venus, several decades ago, it took our only known surface pictures of Venus, for about a minute or two or three before the very hot surface of this planet melted this USSR probe. The average temperture of the COLD SIDE of Venus can melt lead.
Well hopefully humanity can adapt to a Venuisian biology fast due to the climate crisis this little blue speck can become another Venus.
I don't think that humanity will last another 150 years. No one is willing to give up their gas powered vehicle and the government is not doing enough to combat the environmental problems, we will not find any miracle that will take carbon out of the atmosphere or clean up the environment, sorry to say it but that is a sad fact.
Venus is a poor candidate for colonization. The 90-atmospheres worth of crushing pressure at the surface, carbon dioxide atmosphere, sulfuric acid clouds, and 800-degree Fahrenheit surface temperature are just the tip of the iceberg. The real problem with Venus is the lack of plate tectonics.
With no outlet for the planet's internally generated heat through volcanism and subduction fault lines - hallmarks of plate tectonics here on Earth - that heat builds and builds. Eventually the entire surface of Venus, no longer able to contain the heat, turns molten and is completely resurfaced every 500 million years. Over the course of 100 million years it cools enough to re-solidify. Then the cycle starts all over again.
Mars is not without its challenges, too, but they are far more easily surmounted than Venus' will ever be.
No point in messing with Venus, too close to the sun and it will die out thousands of years before the earth does.
Why would you be content with a climate destroying trip to the moon to fulfill your jollies ?

This vid is ill-named. It should be called "Why We Will Never Travel Faster Than Light."
Traveling among the stars is no problem at all, as long as you don't mind the fact that it will take a very, very, LONG time. Many different methods - all perfectly acceptable to the laws of physics - have already been preposed. Suspended animation for the travelers. Generational ships where those that arrive are the descendants of the original crew. If ion drives work, it has been shown that with the constant acceleration you can get to Proxima Centauri in one human lifetime... a one way trip where you won't have much time to accomplish much when you arrive... but we CAN.
Even trade is possible with decades long plans run automatically with no communication needed. So many shipments per year of X in exchange for so many shipments per year of Y for the next 100 years or so carried by automated unmanned craft. That works fine with planning and patience.
Never travel amongst the stars? I scoff. Of course we will. The only question is how distant in the future this will be as we balance our desire to do it faced with restrictions of physics... which aren't restrictions at all if you think in terms of generations of humans and decades and centuries of implementation. And all this presumes that the average lifetime of humans shall remain as is. If you do some research on aging and proposed methods of its prevention, you will see that surprising progress has been made. In a couple of hundred years the human lifespan may have been greatly increased.
It is almost guaranteed that the life in board any space ship won’t last long as space itself is lethal to life
Astronomers found out recently that there are many pockets of space which look empty but are made up of dark clouds with unbearable temperatures and radiation which no life can get thru, the list of dangers in space to any life is endless, there are literally 6 billion way space can and will kill you
So yes the video title is right, humans will NEVER travel interstellar but the AI humans make in the future will since they are not vulnerable biological creatures like their creators
On the topic of trade, why would trade even be necessary? There is an unimaginable amount of resources out there, a small colony of 10,000 guys in Bumfuck nowhere system would possess 1000 times more wealth then then entire earth combined does now. Trade would be a novelty, the only meaningful trade would be that of ideas, and ideas can be transmitted at light speed via laser communications
I believe you. Star travel is going to be very very remote in even attempting/doing such a venture. We will be lucky to visit our nearby planets and setup any kind of structures or space stations around them.

As a kid i always imagined space empires and other crazy stuff.
As i grew up i realized that it is a waste of energy to try it. So much time to get to one place, communication would be a nightmare. All the alien invadong Earth movies look now ridiculous to me.
Why waste so many resources for a war? By the time your planet knows the result of the invasion, your leaders may be dead and theres probably a new party in power or there was a war and people no longer care about you.
It is easier to fix all the problems in your planet than to try and invade others, at most i believe we could land of asterpirds or meteors and extract materials from there.

if you do some basic study on relativity you will notice that due to length contraction, the distance you have to travel to your destination, is approaching zero as you approach lightspeed.

For those of you thinking we could simply travel through wormholes, traveling through wormholes is impossible. You would discombobulate as you cross the event horizon and come out as photons on the other side. It would take literally forever to reach that point, and the radiation would kill you long before. The radiation caused by radioactive decay is the byproduct of the slow process of discombobulation caused by moving across the warp of spacetime.
Why spend decades in a fragile spaceship in order to live in a space habitat around Alpha Centauri when you could live in one around our Sun for a fraction of the trouble, time, danger and expense?
Because we can. Spam in a can. And we can re-spam ourselves to any place we want to go and I think that's a good idea. Think about that dandelion and all those little parachute things when it goes to seed. We should follow the cues of nature.
this is the point that many miss: we already have a space ship / space colony / habitat - and we are not managing it very well
For some reason people don't know about the 1 realistic method for interstellar travel. If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in just 3.6 ship/7.3 Earth years, and this includes turning the ship around halfway to decelerate. This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way. It would achieve about .95% light speed after about 1 year. A 10 ton ship would need a mere 10 tons of continuous thrust.
All that is needed for this is a fission rocket that can put out thrust for long periods and does not consume hydrogen or xenon (you can't bring 500 tons of that with you).
Uranium and plutonium are jittery atoms that are on the verge of fissioning by themselves, there should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion. 1 kg of uranium has the same enegy as 120,000 tons of coal and plutonium has more than that, only a small amout would be needed for the trip.
In an atomic bomb fission occurs when neutrons hit the nuclei of uranium or plutonium atoms, this is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy the same should be true if you infuse them with energy. This might be as simple as having negatively charged atoms coming into contact with positively charged atoms, or perhaps with laser energy.
With the constant 1g acceleration method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to our sun can be reached in under 10 ship years. More info can be found on Wikipedia or watch the video "best method for interstellar travel"
It's not just the engines. You need some sort of super shields or forcefields as even a tiny rock would get massive energy when impacting your ship.
@@mihair2854 It would need a powerful radar. Radar emissions would travel at light speed regardless of the ships velocity. The ship would be at maximum velocity in the voids between systems were the chances of significant mass being in the flight path would be astronomically low.
People once thought humans would never fly or fly through space or go to the moon. Humanity has done all of them, and we will one day travel to the stars with technology we can’t even dream about.
That's why the deep field is so startling. The combined light of stars that are seperated by light years into galaxies and then thousands of galaxies..... we could be looking at the home of millions of civilizations who would never be able to contact each other. And thats a miniscule fraction of the entire universe.
We've only developed modern technology in the last 150 years, and we've made some impressive progress in that time. I do agree however in that in order for us to solve the problem of interstellar travel, it'll take probably thousands of years of human development to break through barriers of our understanding of what is possible. But then again, it's not like we haven't done it before. If a modern person were to take some of the technology we have today and travel 500 years into the past, they'd be burned at the stake for sorcery. On the other hand, what if there isn't a way to break the speed of light or to alter space around you to travel FTL? I guess that's always a possibility, that in fact the vastness of space will forever remain something pretty to look at, but not something humanity will achieve. Only time will tell, and no one alive today will be able to answer the question either way.
Or the scientists working on nuclear power ion propulsion or laser sail technology make a practical drive powerful enough to launch hundreds of probes from the moon to adjacent star systems. We may not get there this century, but there's no reason we can't have probes on the way by then. Exploring the galaxy will of course take a lot longer, possibly a million years, but that's not never. Basically we just hop from one star system to the next until we run into friendly aliens to trade with.
@ApplesWithPeanutButter that's why we should start with nuclear powered ion drives and laser sails. It doesn't get us to FTL, but it can get us to the next star system 4 to 5 light years away. We don't need to travel a thousand light years to a star system when there's one less than 5 light years away.
I am alive and I saw what can only be described as a starship!
This is an idea that proposes that technological progress must be continuous and infinite. It is a faith that forgets how nothing we have done in the past is remotely like interstellar space travel and physics is not cooperating in this matter. Breaking the sound barrier, or flying or crunching digits with a device are simply not comparable to interstellar travel. We worship tech as we once worshiped fire. Fire has its limits. So does tech. We were supposed to have space colonies by now. We even could. But we don't. There are reasons why.

I'm an "older" guy (in years, not in life style). Ex-news-guy, and been putting serious study time into Astronomy, especially the long distances between space objects. For one, the alignment of the orbits of earth and Mars get close enough for inter-planet, only every 26 months. This means that the suicide "voyage" to Mars would be just that, a way to become a gamma-ray bombarded "crispy critter". So this voyage, with any humans, would take a minimum of 2-and-a-half to three YEARS. The "space ship" would have to be half the size of big Star Wars flagship/cruiser. It would have to be assembled IN ORBIT of the Earth, a task that would make the Interna'l Space Station seem like a tinker toy in comparrison. And going to any other planet (mainly Jupiter) would be way too far, a round trip of 5 to 6 years minimum. No human will ever go any further away from our Earth's moon, EVER. The cost would be enormous, and we would not learn all that much more than our various space probes have already done. We know what is there, and practically speaking/witting, sending any humans there is a waste of time, effort and money. { : - } ~~
I forgot to include this: A transit through space will not include any fast-travel portal or wormwhole. These are speculative notions, and a part of what is known as "Science Fiction", and not even remotely available. Wishful thinking, that's why Science Fiction is, and just this: A story not able to be regarded as "true" and/or possible.
Yeah the thing everyone forgets because they're so focused on theoretical propulsion systems is the fact that even if we managed to go fast enough that long-distance space travel was on the table, the REAL problem is radiation shielding. Until we solve the very, very, very real problem of figuring out a practical way to keep our astronauts from getting lethal doses of radiation on their trips, we're not going anywhere.
Our ISS orbits well within the Earth's magnetic field. But radiation was an extremely serious concern on the trip to the moon, even though it wasn't publicised. An inopportune solar flare or other gamma ray event would have had catastrophic consequences for the Apollo astronauts. We just chose to roll the dice and hope for the best, and it worked out. But longer-distance travel will absolutely not have that luxury. And lightweight, durable, and effective radiation shielding is every bit as difficult a problem as high-speed theoretical propulsion.
@@Dr.TJ_Eckleburg Your explanation of these facts is better than mine, and I appreciate it. So now the challenge is to get people to stop believing in Elon Musk's "solutions" to our mutual problem. He and others are neither scientists, nor pay quality attention to scientists WHO ARE EXPERTS in the field of the risks of inter-planetary "travel".
you make excellent points
decelerating from near-c velocity is no picnic either @@Dr.TJ_Eckleburg
We probably could eventually but we're too busy fighting amongst ourselves 😂
Believe me! We will never... wear furs, make fire, float on water, be friends with wolves, herd reindeer, ride a horse, make food grow where we want, make caves wherever we want, etc ad nauseum and everyone's favorite, MAN WILL NEVER FLY!
“Man will never circle the globe, they will fall off the edge of the world.”
“Man will never fly.”
“Man will never go to the moon.”
“Man can not live in space.”

What we know now will beyond obsolete in 5,000 years.
still haven't reached mars, and we've been to the moon ONCE 50 yrs ago... and we don't live in space at all, the international station is utterly dependent on earth, we don't have self-sustaining habitats in space. Humans will destroy themselves and the planet long before any interplanetary travel becomes a reality
@@broo_expungebad for now look at the short amount of time it took just to fly around the earth as a species. A thousand years is nothing to the universe. Just think about the advancements in the next hundred thousand years. Our understanding of physics will be beyond what we can even comprehend right now. Many of the things we know about the universe may even change with the James Webb telescope depending on what data it sends back to us within the next decade. A new era for men is approaching and it’s exciting. I’m just sad that we won’t see it. Being optimistic and finding ways to take on complex issues is always how man has advanced exploration and science.
@@zwanzikahatzel9296 it’s all in time. There is no way we know what the future holds. You got to realize that our understanding physics and the universe as we know now are nothing compared to what we’re gonna know 10,000 to 100,000 years from now. James Webb alone may change a lot of our understanding in the next decade. Let mankind find a efficient way to mine astroids and planets for raw materials. Speculating I think space exploration will no longer be motivated by government budgets but by private entities seeking trillions in profit that they will sell to governments. I think remote drones like the rovers we already have will be sent to work locations with returnable containers. Once enough raw materials are harvested they will wait for the proper planet alignment then take off to return to some sort of consolidation point in space say some private station similar in design to the ISS just material focused rather then science. This will be the first baby steps to colonizing the stars. Don’t forget depending on how the merger of the Milky Way and the Andromeda galaxy goes we have no clue what new planets and stars are going to end up within our reach. I think without being optimistic we can’t advance the science to make humanity and interplanetary and inner galactic species. Just wish we could be around to see it.
The universe and multiverse is a totally different subject.
It won't take 5000 years.
Probably only 500 years
To put in perspective how little we know only a few decades ago there was sort of a consensus among scientists that we would *never* know if other planets existed orbiting other stars. As of today we have discovered over five thousand. "Never" is too long, all possibilities are open.
But HAVE we discovered any? Or just "theoretically discovered". Scientists seem to have great trouble distinguishing between theory and fact.
James Webb can see them at a different level of clarity
@@jondoc7525, If JW scope does discover an intelligent life image it would be worth the 9 billion dollars spent.

Finally someone said it
“Heavier than air travel is impossible.” President of the Royal Society, 1895.

Lmao
It’s scary to believe we are basically stuck unless we discover something huge that changes physics
Scary? Or a relief? The scourge of humanity is currently contained to Earth, whew. What's scary about that?
Uhhh not true. There’s definitely ways to travel interstellar we just aren’t there yet
@@lionelmessisburner7393 we’re never traveling to another star. Modern science acting like false religion did in the past. Delusional
I find it much more scary that because of capitalist greed we seem intent on destroying an environment that we have evolved to live in.
And worst, the speed of light, although fast to us, is REALLY REALLY SLOW compared to the universe. 2.5 million years just to get to the nearest major galaxy. Interstellar travel is extremely difficult, intergalactic is just impossible.
The most disheartening part about this is even if we did the impossible and found a way to travel at the speed of light, it would STILL take us 4 years to get to Proxima Centauri, our closest star system. Space is.... unbelievably massive, so so massive
That’s why warping is necessary if you wanna go really far. Or create “gates” to warp from one location to another. Like folding a sheet of paper so that both points reach one junction, and you’ve “instantly” changed location. Or just a warp drive or some kind, it’ll be necessary if it it can be created somehow
I don't think finding life on other planets is the the goal......having the ability to leave our solar system to find them is.
yes, it would be even better to find "good for us" uninhabited planets cuz it would be "rude" to move in on inhabited ones, even with lower life forms, but maybe microbes would be an exception, if we don't catch a "severe cold" there! ;D
There isn't any solar system pls open your eyes and look up
@@davidsheckler8417 The only thing I see when I look up is blue sky?. I'm talking about far beyond that. If they aren't routinely going to the moon how can they get anywhere else,that's if they actually went to the moon.
@@equinox95 You can't go beyond that
@@equinox95 of course they didn't go to the moon, they paid all the 400,000 NASA prime and sub contractors' workers to keep quite about it too. "Fortunately" they are mostly passed on now. I think they each got about 50,000 bucks, for their silence; that's what made the Apollo budget so darn high (20 bill.)!! Facts, man, facts; glad you agree with me! ;D
There was no mention of "generation" ships where the original crew doesn't reach the destination but their children or grandchildren do. People would be born, live, and die on board the ship never knowing what it's like to set foot on a planet. There are many technical challenges to be over com before any such journey would be attempted, but that's what humans do; explore the unknown.
Saying it will NEVER happen is defeatist language. WE may never travel amongst the stars but that doesn't mean a few generations from now, we won't have the technology to do it.
spend my entire life on a giant ship. NTY
@@plozar guess what earth is
Reading the Stephen Baxter Xeelee Sequence books that deal in part with interstellar travel, and the picture painted isn't a positive one when it comes to generational travel, and for reasons that deal as much with human nature as with the perceived limitations of technology. It certainly won't be Star Trek, or even the relatively more realistic Expanse series. Bummer.
Who'd fund a mega project that they'd never see again or benefit from?
@@edgregory1 it would need to be a global investment. This would come after years of exploration in the solar system showing the profitability of space travel.
It of course would be a colony ship that may or may not be profit-based.
Not all of our exploring was done for profit, the profit was realized after the fact.
Are these the people who said we would never fly, land on the moon, and always ride horses? Those people!?
We are like an ant that lives in your back yatd. That ant will likely NEVER be anywhere else than your back yard. Unless, of course, it happens to crawl up onto your car, and get accidently transported miles away to a different location. 😊
Don't know who originally quoted this but I'll leave this here:
Times are going so fast nowadays that people who say it can't be done are interrupted by people doing it.
We will reach the stars, we have to or we die. No better motivation than that.
Well said!
Dream on. Humans are too puny for prolonged space flight. We are dependent on too many things not easily found in space. Not boldly going anywhere.
@@leonardgibney2997 Elon Musk: Hold my beer.
@@dalethelander3781 Everything l hear about the cosmos tells me, "don't come here". You just have to view say, Anton Petrov's posts to get the flavour of it. People who blandly say men will reach the stars aren't thinking it through. I could write an essay on why they never will but it would take too long. In synopsis we're too puny, distances too great, ambiences too dangerous. In the TH-cam videos debunking Elon Musk they showed how his plans to reach Mars don't add up. There are too many unknowns as well.
Agreed & well said.
This garbage reminds me of that 1899 Charles Duell quote: "everything that can be invented has been invented." If you think we are incapable of the type of achievement that could lead to interstellar space travel, you've obviously not been paying attention to either the 20th or 21st centuries. Can we do it now? Of course not. In 100 years? Perhaps not. To say that it's impossible in light of all the progress that has been made is both ignorance and pessimism of the highest order.
Get off my video feed, noob. lol
The nearest star system is less than five light years away. We only need to reach 10% of light to get there in less than 50 years. We should be able to send a probe at that speed before the end of the century. Given another hundred years we should be able to scale that technique to human travel. Less than two hundred years is far from "never."
And I would like to add, if we can go to one habitable exoplanet in the galaxy, we should be able to colonize all of them in an exponential process.
If we can go to proxima and establish a presence there, we can eventually develop that and turn it in turn into a launchpad to a system under 10 ly from there, etc, etc. With each system we take our capacity to grow increases too. So we get a positive feedback loop of continious growth until the entire milky way is taken.
The most interesting number is the average of the minimum distance between habitable planets in the galaxy. Because you are severely hampered if you have to use Mars like rocks in this process compared to habitable planets.
@@dekippiesip exactly! I figure we can at least average 10% of the speed of light at colonizing the galaxy. It's round, and our path will be in both directions around the outside of the galaxy. The inner parts of the galaxy are the most dangerous for life.
Multiply the diameter of the galaxy by pi times 10 and you have an approximation of how long it will take to colonize the galaxy. We'll also spread out to many other minor galaxies, and be ready for Andromeda when it gets here.
There's one last thing. The problem with habitable exoplanets is they are likely to already have someone or something living there. We may only send scientists if simple life, or trade and diplomatic personnel to those with advanced life. Small planets, moons, and asteroids are the best because they're resource rich, minable, and we don't have to deal with existing life or an existing civilization.
Yep, the problem with this video is it assumes that we need to get to the destination quickly. If we were able to mine resources in space we could theoretically have a multi-generational space ship. Give it whatever time it needs, 100 years, 200 years, ect.
However I think if we were able to live in space for a really long time we may not even need a planet and could just live in space. But of course there are benefits to living near a planet system.
Additionally the video commented on how we wouldn't be able to established trade routes if the distance too that long to conquer. But there isn't any reason the colonies couldn't be independent from earth and our solar system.
Also his proposed solution to the fermi paradox isn't necessarly the correct one.
@@dekippiesip we cant even take care of our own planet, let us learn that first.
@@noujaadw we can do both at the same time buddy.
Iol “if man were meant to fly he would have wings”
The only thing that will prevent mankind from reaching the stars will be mankind surviving itself.
This is based on a very primitive understanding of physics. We are barely 100 years into modern physics and we think we know everything!!!!
I think something that could be said about the Fermi paradox is that perhaps there has simply not been enough time in the universe yet for any civilizations to have developed Interstellar travel. Perhaps it has taken this long for the heaviest elements to have been created to allow for technological civilizations in the first place
Maybe. An even bigger problem to me, though, is the highly anthropocentric notion that technology is somehow inevitable. And it's not, as every other organism on earth except humans demonstrates. Orangs have been here as long as we have or longer, yet still no language and no tech. And now that we've spent the last 75 years making absolutely sure that the rest of our rather enormous solar system is utterly sterile the idea of ubiquitous life is starting to seem a bit absurd. It is so sterile in fact that we are now reduced to hallucinating about floating organisms in Venus' atmo, buried organisms on Mars and ones floating in the dark in subsurface oceans on a few icy moons.
Not saying that's impossible or not worth examining, just that we were actually thinking a century ago that there were advanced aliens living on Mars. How far the fantasts have fallen! We could see their canals, I tells ya!
Yes. Everyone who thinks there is a paradox because we don't see aliens doesn't understand how far apart everything in the universe is, and how slow the speed of light.
What’s even more scary is that it has taken us 4+ billion years to get to this level now, yet one meteor strike could wipe all that progress away.
I think that’s part of why we may never develop anything capable because we would need a massive amount of time coupled with the hope that WE also wouldn’t have destroyed ourselves.
@@ebukaobieri Well, there's eugenics and elitists on earth too. All this doom&gloom stuff I tend to always assume is highly overhyped. Eugenics doesn't happen by itself you know.
They are here for a long time. The Pentagon admitted it in congress. Fermi is no longer a paradox
given how much has happened in just the last 200 years. We really can’t say something is never possible this early.
Yes we can. Everything has a limit. People just WANT to believe these things are possible no matter how much the universe and science is telling us it’s not.
Not by any method of travel we know of, only in the most spiritual, foreign, none-scientifically supported concepts do we have people that can experience vastly more than physical life.
- People with near-to-death experiences. - People who took psychedelics and visited places that sometimes sound like inter-dimensional voyages.
Perhaps nature designed itself as to not be so primitive aswe think it is.
Humans won't leave the nest, no. It's possible that we alter our genome so much that whatever species we become could survive in space.
I'm afraid I agree, unless we find a way to open portals or wormholes, that is if they even exist. Someone made a graphic that shows the size of our 200 light year diameter radio bubble and it's place just in our own galaxy. It's pretty tiny, and it's 100 years of radio waves at light speed in all directions. It took the Voyager probes like Forty some years at 30 some odd thousand miles an hour to reach the limit of our little solar system. Not even seeing us colonizing Mars, honestly. Too many barriers to conquer and think of the vast resources that would be used just to get a few humans there so they can go hide in caves, away from solar radiation.
then how are those ET crafts getting here? like the ones Fravor saw, and that's only one sighting there are countless others.
I think the thought that we are nowhere close to the most intelligent species makes people uncomfortable.
cognitive dissonance or something.
I have seen them too and know SOMETHING is getting here. they have been seen since before WW2 and sightings increased after the first atomic tests.
but don't believe me, go back to burying your head in the sand where you feel comfortable.
I'm sure the world's governments are trying their hardest to reverse engineer these crafts too, and wonder how far they have gotten. as soon as one of them does it will not be pretty. I hope humanity can get along before that happens otherwise ET is going to get a front row seat to our self destruction.
@@LisaAnn777 I don't doubt that other alien civilizations are able to get here, I agree with you there. I just don't think WE will be able to do what they are doing for a long time, if ever. As you said, we're too concerned about 'other' issues right now that pale in comparison.
My god - so those same old radio favourite pop tunes they’ve been repeating for what seems like eternity will literally continue for eternity 🙄
well of course it seems impossible now..but I'm sure millions of years from now humans will accomplish many things we thought were impossible. I mean look at people who thought it'd be impossible to fly and the first airplane was invented in 1903. Then you fast forward 94 years to 1997 and we have robots on Mars. No one would have ever thought that was possible many years ago. I wouldn't be surprised if the first humans to land on mars happens within the next 100 years. Not to mention humans will continue to evolve biologically and technologically to reach greater heights than their ancestors could ever imagine. If you could bring someone back to life that lived let's say...200 years ago they would probably be in awe of the difference in technology. Imagine the technological improvements we've made the last 100 years and try to picture what will be accomplished even 1000 years from now. We know so little about many things at the moment...but I'm optimistic that we'll reach the stars even if it takes millions of years. Humans love and fear the unknown but we always strive to accomplish something that's deemed impossible. You should also look up NASA dragonfly where they'll send a robotic rotorcraft to Titan - Saturn's largest moon in the search for origins/signs of life.
@@PineappleBaconPizza I appreciate your optimism, but I don't think we'll make it that long...
Ok this is a bit if a misconception, there is rest mass and relativistic mass. The object accelerating doesn't actually gain mass. It gains momentum, a 1kg mass traveling at 1c would have a momentum of 299,792 kg m/s (momentum is p = mv).
The error occurs because E=mc^2 is on useful for a mass at rest, not a mass that is in motion, for that you need thfollowing equation.
E^2 = m^2c^4 + p^2c^2
I think it's the difference between gravitacional mass and inertial mass that is usually the same in non relativistic scenarios. We can say that its inertial mass has augmented however measuring against gravity will give us the same result. The question is, what do we mean by mass.
These assumptions that we will simply Rocket our way into space are what make it impossible. I have no doubt that trying to propel a craft to near light speed is impossible. But, the math for a warp drive is being worked out, and the more they work on it, the more likely it seems. A warp drive is warping a bubble of space, the ship inside the bubble is not actually moving. So all of the math around relativistic speed does not apply.
@@alphagt62 well anyone who has a marginal understanding on the topic knows that you cannot simply rocket yourself to the speed of light.
@@sgtjonmcc exactly, I believe I said that,
@@alphagt62 Yes, the Alcubierre Drive (space warping) has been shown to be feasible; at least theoretically. The problem isn't whether or not space can be warped; all indicators point to it being possible. The issue is the amount of _energy_ required to do it. It's several orders of magnitude beyond what we're currently capable of harnessing/building. Think energy on the scale of a black hole.
