Reminds me of the Star Trek episode The Inner Light. An extinct civilization leaves a satellite that contains the entire history of it and draws those who come near and imprints their culture into their brains.
epic episode ❤

Guest bio: David Kipping is an astronomer at Columbia University, director of the Cool Worlds Lab, and host of the Cool Worlds TH-cam channel.
I like the idea that we just haven't been in existence long in a cosmic scale. Like for anyone to even see us, or us to see anyone. People far away would look to earth and see it as it was long long ago. The scale of the universe is so vast we leave that part out really often. We are a literal flash of life thus far. Hope we stay bright.
Some might say humans and the natural world we live on is a blight on existence itself.
There are systems that are only a a few or more light years away. If ftl travel or even close to light speed, it wouldn’t be too long to travel between systems if you could go 60% the speed of light using a gravity drive.
@@mitchdavis6001 that’s craziness. That’s Sci fi. Listen, I love that stuff too. But honestly. Space is mind boggling huge and we’ve been technologically non existent forever really. 200 years of radio transmissions against billions of years and trillions and trillions of miles of distance. There’s probably thousands of civilizations out there. We as a civilization on earth only verified that Mars was a sterile planet just what? 50 years ago? That’s crazy. Even just using telescopes in the 1500’s, 1600’s or 1700’s didn’t tell us anything really about whether there was life on our neighboring planets. We as humans didn’t know anything detailed about our own planets moon until the last 150 years IF THAT. There could’ve been a race of people living there and we could or could not verify that. That’s pretty FN scary if you ask me.
I bet there are some civilizations out there so advanced that they’re capable of looking at earth in real time
Yea what I'm saying. This cooould explain it. I also think it's possible another lifeform or something is Here, or has been here, or could be observing w.o detection. All that combines basically answer the Fermi paradox.
the thumbnail had a screenshot from the movie Contact with Jodie Foster, a 1990s movie. I frikkin’ lovvvvvvved that movie. Even though I had already watched the 1970’s Star Wars by that age, I still really didn’t know what was meant by the words “science fiction movie”. Star Wars was just a really awesome movie to me at that age. But when I saw Contact, it was really the first time in my nascent adolescent life where I understood what was meant by the phrase, “science fiction”. But I also loved the story of the movie Contact on its own.
I've always imagined we could build something out of stone. Maybe in a shape that could be detected like a pyramid, maybe three pyramids in the shape of a star.system.
The only problem is the next civilisation may think they built them.
Paradox?
Love it!
Omg finally !! I love Cool worlds
David Kepping, one of the best. Well done.
Kipping bro. Love your spelling or is it a false memory

“Guys! I figured out how to live forever! Just clone yourself!”
we've been cloning ourselves for billions of years, at least our cells have.
This podcast reminds me of my childhood, when we where high on sugar and use to talk about getting on moon and flying like bird but don't know how !!
Yes, we should be passing our information on like this.
As we go on together we remember all the good times we had together. Niel Armstrong
Hi Lex Fridman! I dont mean to be out of hand or too silly...I love ❤️ this episode among others and your guest speaker is very good ! Thank you ...could you work on a lex fridman movie ?... maybe you could find help writing ideas for this!?.. . Guest stars would be as many as you can find... in my oppinion...Matthew MacConaheuy and others who have already been on the show maybey whatever you think....a person working his way up the ladder in math and so on...lol❤
Makes me think of the star trek episode where Picard lives a whole life to honor the extinct civilization
The moon is also a great idea because we can upload our information relatively easily and timely should something happen.
I think this very conversation should be put on a golden record.
Morrissey really knows his stuff!
Lex: How soon is now?
if Time travel is ever possible in the future then it is possible now🤔
Sure. But what is your point?
@@User-jr7vf it means we’re on the optimal timeline.
Yeah but we don't have access to it
@@nobody6032 only the person who travels back would lol
@@User-jr7vf nvm, you dont get it
This exact idea I had last freaking night no freaking way. That space message we sent out. It's that same thing.
I would recommend sticking with visual pictures and videos and audio. If he was able to see problems with the previous visual communication attempts (a sense we are familiar with), imagine how much worse translation may be in a medium we are not good with.
David knows what’s up
4:28 yes fr compressible dual layer messages
The earth is 4,500,000,000 years old yet the mindset is to only focus on 4,000 years of that life. The same goes for the universe except its age being greater but still we focus on only 4,000 of it and ponder where everyone is... never mind the light we see is the past so we are ignorant of the actual present of that which we see...
The aliens in the movie Arrival sprung to mind. Philanthropic communication.
Indeed, the problem with that is the inverse square law. The idea that some other civilization thousands of light years away would detect our signals, or send their own strong enough to be detected over the interference of that systems own star is really, really silly.
The humility of acceptance isn’t building time machines, it’s just living.
Since most of the universe doesn't interact with light it could be far more likely to encounter an interdimensional alien than an extraterrestrial alien. I bet the constants are more real than waves they're coupled to. There's probably endless other abstract objects besides pi, e, i, etc., that carry meaning to the physical realm as well. IDK somehow something is being passed. If the abstract is more real or more common than the physical, the idea of "tech" "out there" nobody can explain is far more plausible. Like objects defying physics or elves embedding themselves inside you in order to stream their realm in this realm, for example.
Finally, someone who makes sense around here lmAo
Back in the eighties we had a doubt if other planets might exist around other stars. I thought it was logic. Today we doubt about other life and intelligent zivilisations. No doubt, we just have to get to a level to see, hear and understand. No doubt, the time will come. But meeting them...I have a doubt... THX guys
Thats not true.
Interesting
3:07 that's such a romantic idea :) love it
YESSSSS
This universe is busseling with life
Well that settles it, we’re never finding alien civilizations
I find it amazing that we can barely detect other planets around close stars and we know next to nothing about what lays out in the galaxy not far from Earth and yet we find so many people so sure that we are alone... Its so short sighted and such a huge assumption... There are plenty of theories that can explain the fermi-paradox...
The error is being "sure" - in *either* direction. Most statements about the Drake equation make similarly incredible assumptions about its values.
@@MichaelGrantPhD Absolutely - The reality is we have no idea but no one has the balls to admit it
What is space time?
How does the future and the past differ from the present in space. Does space age after the present?
we are the first spark of consciousness in the universe
I have a feeling the 1979 film "Alien" was a really good portrayal of what most alien life is like.
not a chance.
I'm thinking Alf.
Did this feeling start after you learned about that movie? Lol
Probably more like lions squirrels and dogs than xenonoprhs
Actually, I base this opinion on the abundance of ants (and all insects for that matter)on earth. I'm completely serious. If I'm not mistaken, insects and specifically ants make up most of earth's population. Ants are a brutal hive mind, and if they were a bit larger it would be sort of like Alien without the chest bursting and acid blood.
Since you and I really don't matter in the grand scheme of things, why not live life in a way that benefits everyone rather than just you and me?
The opposite proposition is no less rational given your premise. Why ought I desire to benefit "everyone" given that they, too, "really don't matter"? I would think a typical secular humanist view would at least attempt to ascribe some framework of value.
With the infinite size of the universe, why are we shocked we haven’t found nor ever will find life.
Good luck with that 🤣
With the Size of Universe, We cannot be alone folks.
Why not? I mean, sure, we might not be, but why *must* we not be?
these poor scientists keep theorizing while Bob Lazar worked inside an alien ship lol
💀
The kid & dreamer (as well as the discerning skeptic) in me DESPERATELY WANT’S to believe EVERYTHING Bob says - while the rigid, show-me-the-proof-or-it’s-all-bullsh¡t, distrusting, discerning skeptic with his head tilted like a confused/curious dog in me thinks at least SOME of it is just too wild, over the top, fantastical and absurd to believe when the ONLY “evidence”, not PROOF, simply EVIDENCE, is Bob saying “trust me bro”... YET, nearly 2 decades later we get Real world evidence of things like element 115... so...
Lol that fraud
I'm so glad that lexs fans don't mindlessly believe that shit, means I'm on the right channel. Robbie lazar, a story of how a lowly electronics technician could build a 35 yeasr long con so he never needs to work again.
You know that's how scientology and cults work in general (a single figure constantly baiting the fish hook with treats you'll never get)
These "poor scientists" have data-based theories, Bob has a neatly packaged story.
Ah yes. Communication without hope of ever getting anything back.
I know it well.
Perhaps we are not attractive enough to them for any communication.
Bruh💀
Once the first few seasons of The Simpsons are detected by an alien civilization they will be sure we are intelligent and seek to make contact! :-)
in a way, my 2013 Nissan is a time travel device. what would take me 30 mins walking distance, I can do 5 minutes with it.
The voyager probes could crash land somewhere in a million years when we are long gone and be found by aliens.
How is time travel possible if time is Man Made?
Please watch "The Last and First Men." So good and this conversation reminded me of that movie.😌👍🏼
It’s called gobekli tepe
I wish we could time travel already, life is so boring and just, not what it could be if had interstellar time travel. I think the scary thing about that would be if, evil aliens where to be able to track and find you if you wanted to get away from them
Aliens have already left us messages in the form of psilocybin mushrooms haha
Even if the vastness of the universe dictates that there are other life forms out there, we could still be alone. Of all the life forms out there, one of them had to be the first to evolve into intelligent life. What if we are the first ones to become intelligent and all the others will still require millions of years to get where we are
Is the demise of a planetary civilization always preceded by "contact" with an alien civilization?
Why is us being alone in the universe so terrifying?
I can help with this!
Existential horror (the likes of which may be suffocating should you lack sufficient emotional coping mechanisms) ok with you?
Because the Universe is completely filled with darkness and we are alone in it 😅 But thinking more about this, we should conclude that there is no danger being in a dark place if we know for sure that there's no one else in there who could do harm to us.
Why yall mentioning darkness? This is not a case of afraid and alone in the dark. Being the only life raises concerns because, probabltells us life should be there, if we are abs there's so much space. Us being the only ones might mean, we are unique, which is maybe not scary. But it also probably means there's a hard limit and small window for civilization or life t to develope
Yeah, these answers I expect. But guys! Darkness? Aren't we surrounded by raw materials and energy that aren't being utilized?
Isn't this a giant Minecraft-like universe with near limitless everything, and we are the only players anywhere around?
It's a sandbox game, and all we're short on right now is intelligence and labor, right? And AI and automation fixes that shortage?
Exactly, I've never understood the fear. Think about it. If we're the only advanced life, then literally all the energy and resources in the universe is ours for the taking.
"My name is Ozymandias..."
We could bury a time capsule on the moon and a 2001 style black monolith next to the dig site.🌛
After we are long gone, the next species of future earthlings could find it and know they weren't the first civilization to evolve, and probably not the last so possibly not the only ones out there.🐙
Yes great idea
Leaving the monolith as our record of existence purely because it was in a movie is a very human thing to do. But then, again, so would anything else be.
honestly, the monolith is to small, it has be something much much bigger around it.
Yea some big monolith…… something we could make with our technology that would inform the finder of what we’re capable, something big… like a pyramid…. Or giant statues to show our art…. But maybe carved out of one solid block of stone so it don’t break and weathers the ages…… hmmm 🤔 this sounds familiar….
@@jabancho1990 You are thinking short term there. That is only the last few thousand years.
Did anyone else want to reach through the screen and give Lex's hair a pat down?
even censorship says something about us.
What we do now, echoes in eternity.
I think of bitcoin when I heard about this idea of communicating across time.
It’s best believe just ask those who have worked for the government!
Why the Moon and not Just sending somenthing orbiting around Earth?
We don’t want to meet aliens considering how the early frontiers of new lands went. It would be so odd to meet other life though
If you lived on Europa, then not having eyes will be the least of your problems...
A big one will be that you have no fire and hence no tools

We’ll find a way to separate our consciousness from our bodies. We can never travel the cosmos in this form because our flesh just can’t handle the harsh environments of the planets we will eventually visit. The year 1 million is going to be epic!!!!
And if ever humans would become intergalactic species and we would visit other planets I know already what kind of symbol we would draw in the sand there
You could be less ambitious for that project. Humans can visit other planets by being an interplanetary civilization. No need to step out of the galaxy. But I agree in that it would be even more awesome if we could explore other galaxies.
@@User-jr7vf imagination should not be tamed

I am pretty sure we dont know how to look for aliens.
Do you really think they would be using radio waves for communication? Radio waves are soo primitive.
Is that why we visit moons! Lol
The other dude looks like a budget. Anthony Padilla
Doesn't any civilization that may be out there and can actually respond have to be a more advanced civilization? If it isn't more advanced it would be like dropping pebbles in a well but without even the echo of the pebble hitting some kind of bottom. A less advanced civilization than our own would have no way to respond or possibly even see any message. And yet there could be relatively advanced life on that planet.
Human history doesn't seem to be a constant progression of achievement but shows ups and downs. The messages might not arrive at the right time. Like the last scene of Romeo and Juliette, the message(s) are tragically mistimed.
Or the message could be like fishing for a carp but you find you snag a whale. Yippee maybe? Or would it drag you right in after it? It might be a case of be careful what you ask for but I think I'd still want to ask for it. Not that this issue is really something one could expect to see as a referendum.
BTW - When the Egyptians built the pyramids in the new kingdom would you call that the peak of their civilization? I think it comes later and the pyramids were a somewhat stupid use of stone and human labor. They never worked for the intended purpose and the Egyptians gave up on building them. They built much more sophisticated things later - so much of which still remains. But all the time the culture had alternating periods of accomplishment and disorderly collapse. The pyramids may be the early beacon to history but the real story is actually out of sight and mostly derived from the places for the dead. They couldn't find the living. The living had to find them.
I have an idea to communicate with the future. If the spooky action at a distance works also under time scale, not just the distance. As the sender and receiver each get the exact opposite of the same spinning particle up and down, we can suppose this will also works under the different time dilation. Now, this will require a workable device that send signal instantly at distance (not sure if we already acquired it), a predetermined set of possible equations that we want to communicate ,and a mass gravity or a fast travel rocket to stop the time. And lastly, a team of scientist who will sacrifice their life to be living in this slower clock while the earth will keep on dwelling in the future. The comm device will be given to each, the scientists and people on earth. Once the scientist depart into the past people from earth also lives in the future. Now the earth is fast forward to million years and send signal back to the scientist, the scientist then come down from the rocket to tell us what information the future earth sent us. FINN
You have me here.
Doesn't work
Spooky action at a distance can't be used for communication even over distance. You can't affect the particle's eg; spin or position, you can only know what it is, and the moment you know one, you know they know the other, but you can't change it, choose it, or have anyway to know when they discovered their particle's position or spin. I've probably explained that badly, but that's the gist.
@@lukesball1 you can communicate in simple binary choice, eg. If the earth is better off with no technology, reply 1, If not reply 0
@@nigurut Like Luke said, you can only see if there is a 1 or 0, you can't decide if it's a 1 or 0. No information is being sent other than the fact that a 1 or 0 was discovered. In fact, even that information isn't really sent, only that a measurement was made, as far as I understand it.
2:15 :(
Or you bring those civilizations back. Recreate them and their technology based on their remains of DNA and technology. We would have the technology to raise them in a way that they would not know we helped them, disguise our robots as theirs to help raise the first generation. It would suck really bad if we missed most civilizations because we weren't able to help them get over a couple of filters.
The number of solar systems in the universe don't support us being the only planet with life. Our planet is not even perfect for life.
We cant be alone, And I think there are far more advanced than us
@@Sindisile Not only that but I believe life will form anywhere possible, even if it might be difficult to discern as life. As far as I know scientists have difficultly explaining what life is and what isn't. Life formed on our tiny little world in multiple ways and got mostly killed off again and still we are here today. We have only been scientifically advanced enough to ask the big questions for about a 100 years, basically we are still in some kind of stone age but our arrogance makes us think we know a lot.
You're trying to make a Drake equation argument. The number of stars, times the probability that a star has planets, times the probability that one of those planets is compatible with life, times... the problem is we have no clue what most of those probabilities actually are. The notion that there is no life elsewhere is entirely compatible with the current evidence. So is the notion that there is a lot of it. To assume one or the other must be true is an expression of faith without evidence.
@@MichaelGrantPhD There is no evidence, only probability, to think that we are the only life is outright stupid.
@@griffith500tvr the only thing stupid in this context are statements like that. The probability could be close to 100%, sure. But it can also be vanishingly small. We literally don't have enough evidence either way. You have no factual basis for your belief.

Very depressing part of the interview
They look like brothers or father and son it’s creepy
Even if there is a lot of life out there, we most likely will never find any.
I hate when all of these scientists assume that because a plant is maybe billions of years older must have life that has very intelligent life.
Lol these are educated inferences. Not assumptions. And they don't believe them, it's just within logic. Youre most likely, is an assumption and not educated or even cool. Lol
No "ANY WHERE DOOR" IS THE BEST WAY TO FIND ALIENS CIVILIZATION!!! these podcast getting out of control these days 😮💨
