Why Can't We See Evidence of Alien Life? | Documentary 

Utterly, utterly deadly and hostile. Distances beyond the human imagination. We will never leave the solar system as long as we are made of flesh. Edit: If the galaxy was the size of the USA then our sun would be the size of a red blood cell. A reminder of the unimaginable scale and distances we are talking about.

What an odd spot we are at in our evolution. Capable of understanding how futile our dreams are while simultaneously being entranced by them.

Astounding video! Unbelievable computer graphics, very fitting background music and great narrators voice and he's very knowledgeable and resourceful! Just astounding once again! 🇨🇦👍

Imagine if we came together as one world. Used our minds to figure out how to explore the galaxy.

I wish I had a time machine...I want to shoot ahead a few thousand years and just get a PEEK of how far mankind goes or falls..dont get me wrong I'm happy to have lived in a time where we are JUST STARTING to explore our own little system...but man.....I really wish I would be around to see how far we go 😢

Wow!!! What a great documentary. This mysterious universe, continues to be elusive, so far, for our most brilliants minds. Every single day, we learn something new, which is admirable, but, basic answers about the secrets of black holes , I think, will remain unanswered for a long time, probably, forever. Likewise, making contact with intelligent life, I dare to say, that this won’t be possible as long as our civilization exists.👍

Incredible insights into the complexities of space exploration and the search for extraterrestrial life! The explanations about the challenges of maintaining human health during interstellar travel and the theories surrounding the existence of alien civilizations are presented in a clear and engaging manner. I couldn't stop watching

This was a very beautiful and thought provoking presentation. I was consumed and enthralled, very good work.

It takes 45 minutes until the narrator actually starts to talk about the question posed in the title. Skip ahead to avoid the history of space propulsion and the practical challenges humanity faces when going into space.

fantastic documentary. first video i have watched on this channel and subscribed straight away

hi, can you please tell us who drew the thumbnail or what source it came from please?

People today mostly grew up with Star Trek and Star Wars and just for some reason assume this will be possible some day. We have a hard time understanding the huge distances within our solar system. I doubt most of us can appreciate the distance involved with interstellar travel. It will most likely never happen, why leave when you can’t be sure what is at your destination and you already have huge amounts of resources within theoretically possible distances within your solar system? I believe intelligent life could be out there but it doesn’t matter because they will never attempt physical contact.

Also in my opinion I think the governments of the entire world need to actually cooperate and genuinely work together

Time is always left out of these discussions. Why do we think that intelligent life has to overlap in the same time period as our own existence?

I'll be happy living out my entire life on this planet!

It's a mere open question with so many contributing factors to the solution it doesn't even have real implications to the life in the universe. 1) as intelligence is only one of many survival traits its evolution is not granted on a living planet. this alone narrows the multi-planet civilizations into minimum and also limits their technological development due to time potential of the single home planet 2) all species evolve into the specific conditions of their planet, meaning that any migration to other planets and stars will always require full scale terraforming to be possible, which is a major technological step that most of the intelligent life probably won't reach (we haven't) 3) the life expectancy of a civilization might not be very long on a cosmic scale, narrowing down the amount and level of technological civilizations born and the chance they spread to other systems 4) the obvious vast distances of space. the distances are so massive it narrows down the spreading potential of the civilizations again into a fraction of the already small. this also means that those few civilizations who reach this level are bound to spread absurdly slowly across the galaxy, and probably never be able to spread onto another galaxies 5) the space is probably absolutely filled with small space gravel (leftover from planetary collisions and formations) that's nearly impossible to shield but capable of annihilating any unshielded spaceship colliding onto it at traveling speeds. this is especially true inside the solar systems, greatly reducing the amount of civilizations to ever spread out to the stars, as any collision will end an entire colony 6) any radio and similar wave signs of a civilization is minuscule at the cosmic scale, meaning the signs will get lost and distorted to the sheer volume of the background noise of space, and also probably also weakened to nonexistence by the collisions with all the clouds and other matter filling the space. it is also undefined what kind of wave trace should a civilization leave at its different stages of technological development, meaning we don't really even know what we are looking for 7) only technological civilizations give any detectable radio or similar wave trace of themselves to the space, ruling out literally 99,999...% of all life in the universe. while very high concentrations of life technically can be detected via telescopes, we have just barely discovered this technology ourselves and are only starting to study the exoplanets for traces of possible life. and the possibilities of all the different signs a life could leave in its planets trace is not defined, nor is it said that all life will ever effect their planet so much its visible to space. and these are just from the top of my head. it has literally so many contributing factors and solutions that fermi paradox being called a paradox by anyone actually studying life has to be either ideological or paid opinion.

great job 🔝

The introduction to this lecture is undercut by the actual lecture. There is nothing in the footage or commentary to suggest that interstellar travel could be possible within our lifetimes. With all the challenges, it's very much something for the future. And even then, there's the additional challenge of acquiring the funds necessary when the contributors won't be alive to observe (or enjoy) the outcome.

Where did you guys get the image for the thumbnail of this video? I think it's awesome and would love to have that print on a T Shirt

i really enjoy the narrator, feels like im listening to a friend not a pompus professor great presentation

The risk with a generation style ship is that every new seed isn’t always necessarily a good one. You may have a future felon born in the middle of interstellar space and he/she may sabotage the mission out of sheer evil. Imagine a Charles Manson or the Unibomber being born in interstellar space and years later they suddenly “snap” and go rogue and try to destroy everything.

I would be ecstatic if one of our Mars exploration vehicles finds a seashell or the closest thing to one.

What an incredible piece of work! I read a book with a similar theme, and it left me in awe. "Game Theory and the Pursuit of Algorithmic Fairness" by Jack Frostwell

The cosmos, an expanse beyond human comprehension, has intrigued and inspired generations with its enigmatic beauty and unfathomable complexity. At the heart of our understanding lies a singular theory that has revolutionized our perception of the universe

The way people arrive at a large number of technological civilizations is by looking at an extremely large volume of space. So large that few civilizations will be close enough to ever detect each other. We aren't alone in this universe, but we are alone in our part of it.

If we find life in our solar system. Then we must arrive at the conclusion life will evolve whenever the conditions are favorable. As most stars have planetary systems we have to face the fact life could be widespread throughout our galaxy and beyond. The vast distances between the stars may result in mankind never to be in contact with an alien species...

There are vast distances between galaxies. That being said, that vast distance is not unrealistic to cross considering that there is little or no gravity within an expanse without an object such as a planet to create a gravitational pull. It may be more possible than we have imagined. Let me tell you that there are things out there in life that we haven’t considered before, just because you haven’t climbed Everest doesn’t mean that it’s impossible.

Travelling 4 light years at the speed of light does not take 4 years. You arrive instantly. To an observer it will appear to take 4 years but not to the travellers.

Looking at the unfathomable distances, sometimes I wonder if we're going against the grain here.. Perhaps the hostility of space and the intricate requirements and balance therein for an environment to be "habitable" for us indicate we're actually not meant to have contact with one another..... Perhaps we're not meant to be messing around with what's beyond the sky.... I love, for sure and it's fascinating.. I do wonder though..

I’ve watched this for 5 mins and already realize that our only hope of interstellar travel is if they come to us first with their technology and don’t enslave us.

Why the hell are you under 100k subscribers?? This video is top class..

I think what impedes us from growing so much knowledge and reaching greater heights is spirituality separated from science for the knowledge we have now about science was passed through to us from those who were revealed to

Sorry for stupid questions... how do you slow down after traveling 90 percent speed of light?

after watching 19 minutes, it's hopeless case and I am really disappointed and sad that it's almost impossible that mankind would achieve any breakthrough discovery regarding interstellar travel or extraterrestrial life in my lifetime at least

Well done!

Your vedio simply blew my mind. Thank you

Okay so correction, if you travel at the speed of light, the journey would not take the trip four years from the ship perspective. It would only be 4.2 years that passed on Earth***. Time dilates, so at 99% the speed of light, you'd essentially arrive at alpha centauri INSTANTLY from the traveler / ship point of view. You would NOT be four biological years aged either. The trip would seem nearly instantaneous.

Concepts and theories. We're not going anywhere but extinct. So much for that unforgettable journey you alluded to at the beginning, but by all means feel free to move about the cabin.

Never ceases to amaze me how someone can know so much and so little at the same time, but that is the wotld of theory! It's all theory and no substantiation.

Kudos to the selection of the narrator....: Clear annunciation and the lack of his customary southern accent indicates that it is Jeff Foxworthy...!! ....^ 5...!!

I would like to believe that there are more advanced extraterrestrial life than humans, they have very likely visited Earth at some point just to see how our technological side is advancing or perhaps even kickstarted our planets evolutionary movement in the first place. But those extraterrestrials have very likely also grown past petty wars and religions, which allowed them to advance quite a bit more and faster.

3:10 - antimatter is the key, understanding and controlling it to bend space and create a wormhole is the only way to feasibly do interstellar travel. My concern is I think the only thing that can survive a wormhole is consciousness, so we'll need to understand that to the point where we can transfer it. Equally, for us to work out these issues, the key is understanding quantum computing and mechanics, that will lead us where we need to go. Give it around 50 to 100 years

Should watch life beyond the best doco I’ve seen so far an it’s well presented

With The "Horizons Paradox", maybe if the mission were multipurpose in advancing technologies using space time dilation to our advantage making those souls that chose to be "Scouts" would contribute in many respects such as navigation, communications and other exploratory adventures

A very interesting subject to ponder concerning aliens. Maybe we are not at a level of technology, compatible with E.T.'s. I am also, assuming they are already here.

are we alone in the universe or are we not. I find both scary👩‍🚀

I have been in telepathic contact with ET for 7 years. We met in a grocery store After we left the store she identified herself to me and we have been in telepathic communication since that day. I often wonder how many ET /Human friendships there are in this world that are under the radar.

Man I love this documentary... I have seen it 10 times.

It would take 4 years for the people on earth.. the people in the craft moving at speed of light experience time dilation and it passes quickly for them.. they kind of travel to the future relative to ppl on earth though.

We're probably closer to AI singularity than we are to interstellar space travel. Our AI overlords will most likely not let us explore space once they take over.

Each galaxy has its own civilisation. There’s millions of galaxies and endless amounts of planets and I honestly believe they all contain life of some sort. I also believe we are so far apart in distance because we are not meant to mix or communicate as we are all at different stages of evolution. Another theory I have is that once you die and depart this world you transfer to another plane to be reborn and keep bouncing round as energy cannot be destroyed x

Imagine we put all our time, effort and money into things like this rather than making weapons to destroy each other.

I really hope when the epic meet & greet day comes, that they give us the tech to really explore our galaxy. Also if they could get us to the point to where we are at peace with one another & don't have need for war between each other. Therefore we can actually make headway into things that really matter, but since out defense budget takes up the majority of the funds its impossible at this stage. Yeah I know that one is a child's wish & the way the human race is biologically programmed to destroy it's self & kill one another. That it's impossible for that day to ever come but a guy can still dream for that day. I just hope that the ones that are here now & observing, studying & messing with us. Don't decide that we don't serve a purpose anymore or if we advance anymore that we are a danger to let live. So they just decide to wipe us out entirely, so everything & everyone else can live on & flourish.

consider using Webway or even warp tech for interstellar travel?

The vast distances in space are only part of the problem. Civilizations also need to exist at the same time. Time is as vast as space. The odds are really small given our current place in the universe.

When we travel by the speed of thought, only then can we reach the stars.

We are not alone, but the nearest neighbor is so far away, we will never meet.

The thing I find humorous about talk regarding suspended animation for long term space travel is that is doesn't slow aging, right?

How do the things fly into space without getting hit by asteroids or rocky debris

I live near by Hessdalen (Norway).. a known ufo hotspot. In 1947, a huge round metallic/white object crashed into a lake called djupsjøen. Just behind my house. We call it `the egg from another world` A major streaming service is making an episode about the egg. Theres also a big search team there right now doing investigations. i and many others who live her have seen ufos and many strange things in this area. Most weird is something that looks like a portal opening and closing in the night sky. Ive seen that many times. At the end of the 80s there was a mass sightseeing of a huge craft standing on the ground in a valley. There was 80 people who witnessed this, my dear old aunt was one of them. The craft emerges from the valley and start to spin at tremendous speed, morping into light and then shoots of to the sky, gone in a second. Left behind is a black smoke. Aliens or not, something is here that we know nothing about.

Or you can make contact with Aliens and ask them, that would be faster and easier , rather then wait for millions of years. Just saying 😂

We really can’t say to wait to future tech because it’s waiting for ever or better future technology, this paradox is there will always be better future technology. A generational ship broke down to single generation goals or missions to colonise space and expand, develop and explore but always continuing the mission

This is great, it's like some post space-x stuff, where ho hum, here's how space travel works. Not mocking it, it's great, comes across as very realistic and near/current term as far as the tech goes.

They've seen us and kept on going. We can't be good to each other much less to a being from another planet. We'll be lucky to make it another 50 years, anyway.

We have seen intelligent life! I’m a 54 year old business owner and we witnessed three craft hover for 15 or twenty minutes over a pasture on our farm. Something is here

Not to mention that seperateing is impossible to make a smaller explosions than the normal sizes that their creating and having a engine that can cause the ignition of the antimatter magnetic convayer belts and the floating density of space itself is a Tallow of vibrations that resonances FALLOW through with out dependency on anything else

I believe there are plenty of diverse life and intelligent life in the universe, but unfortunately, i do not think it is in our galaxy. Maybe microbial or small animals exists but thats it

I believe aliens are all around us all the time, but we can't see 4th and up dimensional beings from our 3d dimension perspective, but they can see us.

The universe is still fairly young. Perhaps we are some of the first. We might be the ancients, in a future time.

Reaching proxima centauri going light speed would take 4 years from Earth perspective, but from the spacecraft perspective wouldn't it take drastically less time?

Welding rods along a spiral pathway that sparks the fields into motions that's a Clampet of vacuum charge that is so entrenched in vibration so allowing the charges of a distant location outside of the sun's surface creates a very large scale propulsion system 😊

We are here..its nieve to think we are the only life form in this unimaginably large universe...life must be rampant

We’ve never been alone.

"To unlock the future we must 1st find the keys to the past" Lenard Nemoy. We'll, you haven't found any keys yet, but J. Terran is here to offer you every key you will ever need.

Extraterrestrial craft have been seen for decades even acknowledged by most governments mainly USA, Argentina and Italy, so where have you been the last few decades.

We can't see other life because JWST is looking at as it was billions of years ago. It's there. We just have to wait billions of years for the light to reach us.

I am pretty sure other civilizations out there are older than ours,just because the direction of the universe's expansion,but if we ever meet,am quite sure that after travelling for trillions of kms/miles,those aliens are going to be needing fuel,hydration and food..I don't want to be their food source.

Incredible!

I think there must be a generous number of civilizations out there, but we haven't seem them yet. It is logical that in the milky way life has developed, but is not advanced enough to comunicate with us.

I'm 100% certain we are not alone space is just to big for earth to be the only safe haven

hire me as a scientist I'm real deal I'm from the future

I never understood the fuel requirement for space. Getting into orbit sure to refuel, then a slight burst to begin heading out. You'd be moving with 0 resistance using slingshot orbits to get to the target. With 99% fuel left for coasting. Weight shouldn't be a factor once projection begins with nothing to push back.

My hypothesis to the dark Energy mystery is that the super massive black holes gravity in the event horizon; were gravity is at its strongest, is the same gravitational force that is pushing space outward in another parrallel universe in the form of a White hole, which space is still spreading across our own universe faster then the speed of light. 🔭👨‍🔬

We are most certainly not traveling interstellar in this life time

We are never alone in the universe. The universe is full of conscious advanced beings. Just as we are looking for aliens, they are also looking for aliens. The cosmic constraint of all conscious species is that we cannot see each other due to dimensional differences.

One way to shield Astronauts from radiation might be to build a Spaceship with a Hollow hull, and to fill it with an inert gas, such as nitrogen or something even more protective ! That would be very lite and protective ! DML.

Solar Sails as a means of propulsion to the stars ? What happens once the spacecraft travels that distance that the sun/stars influence/solar wind is no longer a means of propulsion, Our Voyager probes are into interstellar space but are now basically adrift and our sun's energy no longer affects them

Until I see absolute evidence then yes we are alone 😐

Let me save you some time. Interstellar travel is impossible.

Why would anyone even begin to think that its possible to live out your life in a small ship moving through space with other people. Everyone would go insane. Just look what happens on a cruise ship that gets denied port access due to quarantine.

I felt asleep a few mins after the beginning of the video and woke up at 40 mins in already.

There's someone else here. Watching 👀 over us. I don't actually know how many. However, I can confirm one true living powerful spirit like no other. Looks like this one can always be around anytime, anywhere. We have never been alone. That's impossible and important to know.. we are being visited by the one true living spirit that created everything. All it takes is one to truly exists and go to work through the universe and all of the great ideas are now on full display. It's something going on before us that may still have a role to play. There maybe a race that became to extreme before mankind was stripped without those abilities given to the ones that caused war in heaven. So heaven is way beyond our reach and imagination another place prepared. So that alone my students is clear evidence there is intelligent life in the universe.

I hope potential advance civilizations are preparing to attack capitalism on earth.

Fantastic documentary

Think of the walls of intestinal tract tissue and the vastness of inner points of actions that retracts from a distant flow

Light speed travel will never be viable for long distance journeys. You can only travel forward at that speed for the distance you can confirm no instructions in the pathway. That being said that distance to each cleared destination is halved due to the equal distance required to put the brakes on as it were.

Human kind is still very young. Imagine a society 1000 years ahead of us.

you have to develop reverse gravity, that's the only option you have. no amount of fuel or engine will be able to get that speed and distance. engine of whatever kind has a limit.

"Love stuff like this to fall asleep to. (Not in a bad way) Has to have the right kind of voice👍"

BRAVO!!!!!!!!!!!!!!!!!!!!!! upvoted!!!!!!!!!!
