It's my daily dose of hope for the future. I recommend using the internet literally anywhere else if you approach critical levels of hope, it will instantly remove any hope you may retain. Then come recharge in a slightly more measured manner.
This reminds me of the book "the eternity artifact" by L.E. Moddeset jr The find an alien structure far above the galactic plane, and work out that aliens had used it billions of years ago to travel to a younger universe
EPISODE SUGGESTION: Detection Ranges. Any channel regular knows that there are virtually limitless activities that civilizations may be up to, ranging from campfires, through tiny space probes all the way (and possibly beyond) to moving entire galaxies. I wonder what the detection ranges are for various activities in three categories: 1) How far can something be detected, assuming extreme luck? This could be something like a laser communication sent to someone in line with the Earth just as JWST is looking in that direction. 2) How far can something be detected by reasonable telescopes and it be determined as more likely than not to be artificial? This could be a laser detected by Kitt Peak, with a spectrum, and another at the same location detected days later by Hubble. 3) How far can something be detected by anyone and only the most stubborn refusing to believe it is artificial? For instance, a laser bright enough to appear as a new star in the sky that blinks in prime numbers.
It's an interesting general question, although since all your specific questions boil down to spotting lasers, the answer is that you won't. Not unless it's actually aimed at you. Space is too big, laser beams too small, and _everything_ is moving too fast.
Future episode idea. Grey Goo as Fermi-Paradox solution. Any sufficiently advanced civilization eventually creates self replicating nanobots that convert everything into paperclips
Flip that and say it’s the paper clip maximizer is what’s currently limiting expansion of all prospective space faring civilizations. Like the replicators from stargate nemesis.
When we have bigger rockets we will get to know more about the universe with space telescopes and other space based technology so it is great, today we're advancing our rocket technology at a really fast rate...
The use of crude oil as an energy production is a great filter event. The ability to make intuitive connections between a seemingly useless byproduct and a planets ability to play host to a living ecology.
And they replenish over millions of years but get used up in only centuries. If society collapses and has to restart, they won't have any left to use. Not easily accesible anyway.
@@cyruspowers7355 the trouble with that is its actual purpose ... I posit that the crude that is deposited in the crust eventually gets subducted into the earth's mantle and once there, it interacts with the h2o and oxygen Locked up in minerals and metal oxides, smelting them. Adding to the dynamo that creates earth's electro magnetic field... Do you see what might happen if humans parasite Any fuel from that cycle?
@@dansmith1661 And, the cycle relays on the presence of microbes right from the get go. As soon as there was liquid water, the microbes began to reproduce, making grease and dying, building up the crude oil, "the boring billion" was because microbial life hadn't yet built up sufficient biomass to start the algae and plankton cycling biomass into the seafloor... Kinda makes archaea and microbes some sort of ecology making Von Neumann probes...
The current crisis is in no way a great filter event, not even close. Has its negative consequences of course, but nothing close to extinction or even societal collapse. That’s not even considering the fact that alien biology or geology wouldn’t guarantee the formation of crude oil or similar sources. Maybe the lack of such a useful energy source to kick off more advanced technology could be a filter though
The idea of migrating to a cluster of young stars with cooling planets is just so moving and inspiring. I get so used to listening to and talking about sci fi and futurism that it feels mundane. But then every now and then I'm struck by how profound these ideas are. It stirs something inside of me like nothing else does.
It always amazes me how tin foil can move us across the universe. I tried explaining to my wife and she just thought I was insane cause I was trying to pull a star with some imaginary rope of Tin foil. So even when I explain it thoroughly she looks at me like I'm some mad scientist. To that I say, Pah, the other great mystery of the universe: Women!
This gives me an interesting idea. If there, for some reason, is some decline of civilization and civilizations migrate to the core, then the core would end up being a graveyard of ancient civs and overall be an archeologist's wet dream
I dont like thease ones they require the whole civilisation to conform to the same plan. One community at least must reamaim sticking back in the paradox.
Hi Isaac, have you seen the latest from Antron Petrov about Terraforming Mars? It's about a research to use tiny aluminum rods that can act like a greenhouse gas to warm up Mars. With the pro's and cons about it.
a) it might be a hassle if multi-universe is possible and 'easy' to do, BUT is quantumly random as to which other universe is traveled to selected, each and every time, and thus in practice one-way due to the chance the way back to the original universe is absurdly tiny, and as another limitation being the amount of matter/people/things traveling as a single unit (ie travel attempt) is too small to start a new 'colony'. b) while travelling to a less advanced alternative universe might be more likely, it's not guaranteed - and could quickly win the travelers a Darwin Award, and their home universe as well if two-way travel is viable, where they get greeted with a "thank you for showing us, a new rich universe to plumber ... we won't be needing you alive anymore." c) some of the other multiverses are those that had more antimatter than matter ... so first contact is a 'liberating experience' that converse both universes into a chain of mutual energy-matter rearrangement - or travel requires breaking a false zero-point energy state and triggers an energy state collapse to spread in the universe you are leaving or entering .. woops. (I forgot the correct terminology - but I'm sure someone knows it)
The biggest problem I have with the Fermi Paradox is that it operates under the assumption that we would be able to tell when an alien life form is communicating. That's one hell of an assumption when dealing with Aliens.
It can be broken down further, the assumption being made is not actually about being able to tell if an alien is communicating, but rather can we distinguish between nature and artifice of whatever form that is detectable.
Your channel is awesome, your voice is undesirable but it only takes 10 seconds to get used to it. Like listening to a cell phone video of a live band that you love
I feel there's a really big factor here that isn't touched upon is how much rests upon the assumption that the design of minds always remains somewhat mysterious and ineffable. Though maybe you get into that in that nebula video I haven't seen. The calculus changes considerably if you understand all the deterministic causes of a mind's behavior and can either eliminate true randomness or just counteract it with denoising measures. In that case you should be able to be quiet confident in allowing pretty free colonization so long as an overseer AI is present with which can easily forsee and preemptively nudge the culture away from value drift. Though having something to provide subtle nudges to the culture isn't even necessary if you just pick the right mind design for the colonists. After all even for selfish reasons people may wish to choose to alter themselves so that their values become less malleable, so they don't have to worry about gradually changing in ways they wouldn't have endorsed from the outset. So why wouldn't future people just choose a mind design for the children they create (or simply alter themselves in a way that's heritable) so that it's literally impossible for them to end up developing irreconcilable value differences in the first place? Honestly I think choosing not to do this will eventually be considered abhorrent, for the same reason the existence of psychopaths is a problem of evil issue if you believe in a benevolent god.
@Toxicpoolofreekingmascul-lj4yd I didn't say psychopaths were evil, psychopathy is just one trait that exists on a spectrum alongside other antisocial traits. You're sort of missing the point though that psychopathy does absolutely predispose people to shittiness, it certainly seems like most of the loved ones of people with psychopathy don't exactly have overwhelmingly positive things to say about it, kind of like the loved ones of narcissists. So given what we know about psychopathy in aggregate it would seem very hard to justify having a kid with psychopathy when you could just as easily have one that didn't. If this logic doesn't seem obvious to you I can easily make it even more extreme: Say instead of just knowing a hypothetical child would have psychopathy you also knew they would be an impulsive narcissist with strong sadistic tendencies. At what point do you think it would be unethical to create someone you know will almost certainly cause tremendous suffering to the people around them?
Fixing a society's reactions can be dangerous if said society comes across something outside the fixers experience. Read (or re-read) Brave New World and you will see a society optimised for the economy of first half of the 20th Century which would struggle with meeting a society such as ours.

Was not expecting the episode to become GURPS: Infinite Worlds! I'd be more than happy if that sort of thing were possible, as long as we don't end up battling the evil forces of CENTRUM or Reich-5
I agree that it would make more sense that once you reach the point of knowing how and having the technology to do it that an advanced civilization would just create it's own star cluster.
At about the 45 minute mark you were saying how 1 dimensions light speed could be 100 times higher. Sounds like a good way to get around if FTL is impossible
Regarding moving to the core, I've always figured it's the obvious place to head to and look at if we want to find other civilizations. It's the one truly unique point in the volume, so regardless of resources it seems to be the obvious meeting point. But in terms of colonizing the center, wouldn't the higher density of stars present problems? More likely to get disrupted by the gravity of all the close by neighbors and more likely to get hit by a super nova or similar catastrophic space weather. Are those concerns really not that elevated near the galactic core? Or are we expecting a colonizing civilization to be able to deal with them?
Actually, waiting untill the end of time doesn't really make much sense when you think about it. On the one hand it might be true that any resources that you have collected may last longer from a energy perspective, wouldn't it also be true that much of your collected resources would be lost just through half-life degradation if you're waiting potentially hundreds of billions of years or trillions for the end of time.
It took 200 years of heavy migration and building infrastructure for the united stated to become a technology empire. Bright side of our solar system, we dont seem to have any native intelligence that we would need to commit atrocities and fight wars with to steal their area. Id sign up now if it was available, id really love to go help set up a colony on either Luna, Ceres, heck even vesta. 200 years it would be a "small" Metropolitan hopefully
Hi issac arthur! A civilization who is capable to travel better two star (type 2 civ ) would need a planet to live? I guess their spaceship would be better than planet itself
They would not need a planet. Some might find a planet nice if one is available, but if you’re traveling slower than light the star itself is more valuable.
This feels like "Well we already have it and all our infrastructure is there." solutions. Practically speaking the planets are a rounding error in the mass of moving the solar system so there's almost nothing to be gained by trying to kick them out of orbit when you move your star and most or all of your stuff is already built on the planet. As a plus you don't need to spend energy to protect it since it can survive lots of accidents that would wipe out a ship and it's large enough that its life support system has a pretty big buffer so your habitat maintenance can be pretty delayed without unbearable consequences.
@@OOL-UV2 you think like such a 21st century human. It's like people of the past wondering how to make a more efficient horse and cart. Free your mind of its assumptions, look at the available evidence, and then you'll be thinking about this topic productively.
@@OOL-UV2 Gee, it's not like Isaac talked about moving solar systems in this very video. As you mentioned, the planets are rounding errors in the math, and it isn't as if a Shkadov Thruster produces much acceleration. To be clear: moving the star will drag the rest of the solar system with it.
I mean, that would be quite a reasonable explanation actually. There might be some sort of "easy" way to trascend into another dimension where everything is more convenient that "only" takes a couple of million years to solve. That + FTL isnt real would account to why no one proceeds to interstellar colonization, even if life appears it either goes extinct or arrives at this conclussion.
Hmmm... good point on AI or civilizations who achieved (near) immortality - if you gonna live 'forever', why would you produce more of, or seek to meet others who will live 'forever' as well. At that point they are your rivals and it's not in your interest to have more of them...
If you want to have civilization in the ocean, which is easier, modifying humans to breath under water, or uplifting critters that already know how to breath under water to form their own universities?
There are some theories that suggest that black holes might be the "outside" of a new big bang creating a new baby universe. That's the only one I remember, but I think there are a few more theoretically possible methods.
24:50 Can someone explain to me why most if not all Einstein rings I have seen have a Red dense old galaxy in the middle surrounded by a blue ring? Shouldn't the more distant object, the thing being projected as a ring, be far more Red shifted then the Lensing galaxy? Is it something with the way the Einstein ring forms bending and maybe compressing the light waves or what?
Isaac, you may want to consider uses for the exaust resulting from moving the sun into the core. Could it not be used as a raw material matter stream and propusion for a massive antipodal armada voyaging out of the galaxy at the same time that the sun is moved inward? It seems wasteful of such a useful resource to just shoot it out to no further purpose.
The crazy thing is we have the technology now to crawlonize the soloar system and even the next closet soloar systems. Its just very dangerous and very expensive. But the biggest hindering factor is the cost would exceed the entire earths gdp for man many years 😅
"A long long time ago in a Galaxy far far away," there was quadrillions of beings in a great galactic empire that had their own problems so that they could only take over 80% of their own Galaxy and did nothing to colonize other Galaxies or even try to communicate with them.
To be fair, in legends cannon, there was some force barrier or something that prevented easy hyperspace travel. Something like that anyway, I'm not 100% sure, it's been a while.
Building a megastructure is easier than inventing space magic - the former just takes unity and coordination, the later... just requires you to break laws of our reality. "The Wandering Earth" appears plausible to the Chinese because they're already building megaprojects, just need to scale it up some more. "Star Trek" appears plausible to us because we're already smoking pot, and just need to legalize it. In retrospect, it's easier to confuse magic with reality than building something solid and real in that reality.
The multiverse concept is well explored in M.R. Carey’s Pandominion Series; the second book - “Echo of Worlds” - was recently released. Any other good multiverse series recommendations?
Population pressure usually plays a big role in migration, or at least colonization. It seems that with humans, once technology and the standard of living reaches a certain level, birth rates fall to below replacement levels. If this is something of a general rule that applies to all intelligent species, that alone might explain why we don't see evidence of star spanning civilizations. If they stick with old fashioned reproduction they would struggle to keep from dying out. If they use artificial wombs to grow children, that would mean their government is probably doing the creation and raising of new generations. A government is highly unlikely to over produce new citizens since this would put stress on resources and infrastructure. Besides, a large and fast growing population is one that is increasingly difficult to rule, and one that's given to political upheaval. It's likely such a government would grow its population slowly, if at all, and only boost its population in an emergency like war with another civilization. Even the latter assumes it needs lots of warm bodies to fight instead of just mass producing machines to fight for it. Without large, regularly growing populations, much of the drive to settle other star systems and planets, or even to create mega structures evaporates. The only motivations left are to satisfy curiosity, war, or if the home system has been largely depleted of resources and the star is at the end of its life cycle. This would mean minimal and sporadic migration/colonization efforts, and so little technological footprints we could observe from here. The galaxy could have a fair number of technological civilizations, but it could be like an small town out in the countryside, populated with noting but old people who have what they need, aren't interested in travel or meeting new people, and are content to be practical shut ins.
Right now in the Andromeda galaxy there is much older and more advanced society that has colonized hundreds of star systems around them. They only use low power energy efference light bulbs so humans will never be able to see them. At 2.5 million light years away they are able to see the earth and are debating if all those giant lizards are going to do anything in the future.
Interesting concept..tho I suspect vacation or pleasure worlds capable of supporting multi species organisms are going to be RARE. Otherwise..exploration always is the vanguard for exploitation….
This channel gives me a lot of hope for the future. That's something i honestly need right now.

Are those concerns really not that elevated near the galactic core? Or are we expecting a colonizing civilization to be able to deal with them?
Actually, waiting untill the end of time doesn't really make much sense when you think about it. On the one hand it might be true that any resources that you have collected may last longer from a energy perspective, wouldn't it also be true that much of your collected resources would be lost just through half-life degradation if you're waiting potentially hundreds of billions of years or trillions for the end of time.
Yayy Arthursday.
Epic as always
It took 200 years of heavy migration and building infrastructure for the united stated to become a technology empire. Bright side of our solar system, we dont seem to have any native intelligence that we would need to commit atrocities and fight wars with to steal their area. Id sign up now if it was available, id really love to go help set up a colony on either Luna, Ceres, heck even vesta. 200 years it would be a "small" Metropolitan hopefully
Hi issac arthur! A civilization who is capable to travel better two star (type 2 civ ) would need a planet to live? I guess their spaceship would be better than planet itself
Why do you assume they exist in space?
They would not need a planet. Some might find a planet nice if one is available, but if you’re traveling slower than light the star itself is more valuable.
This feels like "Well we already have it and all our infrastructure is there." solutions. Practically speaking the planets are a rounding error in the mass of moving the solar system so there's almost nothing to be gained by trying to kick them out of orbit when you move your star and most or all of your stuff is already built on the planet. As a plus you don't need to spend energy to protect it since it can survive lots of accidents that would wipe out a ship and it's large enough that its life support system has a pretty big buffer so your habitat maintenance can be pretty delayed without unbearable consequences.
@@OOL-UV2 you think like such a 21st century human. It's like people of the past wondering how to make a more efficient horse and cart. Free your mind of its assumptions, look at the available evidence, and then you'll be thinking about this topic productively.
@@OOL-UV2 Gee, it's not like Isaac talked about moving solar systems in this very video. As you mentioned, the planets are rounding errors in the math, and it isn't as if a Shkadov Thruster produces much acceleration. To be clear: moving the star will drag the rest of the solar system with it.
Nice. Love the fermi series
I mean, that would be quite a reasonable explanation actually. There might be some sort of "easy" way to trascend into another dimension where everything is more convenient that "only" takes a couple of million years to solve. That + FTL isnt real would account to why no one proceeds to interstellar colonization, even if life appears it either goes extinct or arrives at this conclussion.

Hmmm... good point on AI or civilizations who achieved (near) immortality - if you gonna live 'forever', why would you produce more of, or seek to meet others who will live 'forever' as well. At that point they are your rivals and it's not in your interest to have more of them...
If you want to have civilization in the ocean, which is easier, modifying humans to breath under water, or uplifting critters that already know how to breath under water to form their own universities?
cross-multiverse travel is indeed possible, but can only realistically be done in a clockwise-direction.
I don't understand the part where he says that a new Universe being born doesn't have to be a computer simulation...
Can someone please explain?
There are some theories that suggest that black holes might be the "outside" of a new big bang creating a new baby universe. That's the only one I remember, but I think there are a few more theoretically possible methods.
24:50 Can someone explain to me why most if not all Einstein rings I have seen have a Red dense old galaxy in the middle surrounded by a blue ring? Shouldn't the more distant object, the thing being projected as a ring, be far more Red shifted then the Lensing galaxy? Is it something with the way the Einstein ring forms bending and maybe compressing the light waves or what?
Isaac, you may want to consider uses for the exaust resulting from moving the sun into the core. Could it not be used as a raw material matter stream and propusion for a massive antipodal armada voyaging out of the galaxy at the same time that the sun is moved inward? It seems wasteful of such a useful resource to just shoot it out to no further purpose.
Thanks!
The crazy thing is we have the technology now to crawlonize the soloar system and even the next closet soloar systems. Its just very dangerous and very expensive. But the biggest hindering factor is the cost would exceed the entire earths gdp for man many years 😅
Civilisations migrate into hyperspace bottles. Much safer there.
Civilization, alien, might have been before us, or later. Time is what you need to understand
"A long long time ago in a Galaxy far far away," there was quadrillions of beings in a great galactic empire that had their own problems so that they could only take over 80% of their own Galaxy and did nothing to colonize other Galaxies or even try to communicate with them.
To be fair, in legends cannon, there was some force barrier or something that prevented easy hyperspace travel. Something like that anyway, I'm not 100% sure, it's been a while.
@@VainerCactus0oh, there was. The threat of Extra-galactic invaders was discounted exactly because of that barrier.
Building a megastructure is easier than inventing space magic - the former just takes unity and coordination, the later... just requires you to break laws of our reality. "The Wandering Earth" appears plausible to the Chinese because they're already building megaprojects, just need to scale it up some more. "Star Trek" appears plausible to us because we're already smoking pot, and just need to legalize it. In retrospect, it's easier to confuse magic with reality than building something solid and real in that reality.
Globular clusters have little to no planets orbiting stars

What are the odds of crashing into a rogue planet while traveling through the galaxy with our sun?
The multiverse concept is well explored in M.R. Carey’s Pandominion Series; the second book - “Echo of Worlds” - was recently released. Any other good multiverse series recommendations?
The Long Earth by Terry Pratchett has a novel take.
All the Myriad Ways by Larry Niven is a short story that explores aspects other stories usually miss or ignore.
Ooh, look it’s Barry kirpke from bbt
isn't the core a way more dangerous place. the chance of contact or influence is a lot higher.
Perhaps you go there because you want contact
Population pressure usually plays a big role in migration, or at least colonization. It seems that with humans, once technology and the standard of living reaches a certain level, birth rates fall to below replacement levels. If this is something of a general rule that applies to all intelligent species, that alone might explain why we don't see evidence of star spanning civilizations. If they stick with old fashioned reproduction they would struggle to keep from dying out.
If they use artificial wombs to grow children, that would mean their government is probably doing the creation and raising of new generations. A government is highly unlikely to over produce new citizens since this would put stress on resources and infrastructure. Besides, a large and fast growing population is one that is increasingly difficult to rule, and one that's given to political upheaval. It's likely such a government would grow its population slowly, if at all, and only boost its population in an emergency like war with another civilization. Even the latter assumes it needs lots of warm bodies to fight instead of just mass producing machines to fight for it.
Without large, regularly growing populations, much of the drive to settle other star systems and planets, or even to create mega structures evaporates. The only motivations left are to satisfy curiosity, war, or if the home system has been largely depleted of resources and the star is at the end of its life cycle. This would mean minimal and sporadic migration/colonization efforts, and so little technological footprints we could observe from here. The galaxy could have a fair number of technological civilizations, but it could be like an small town out in the countryside, populated with noting but old people who have what they need, aren't interested in travel or meeting new people, and are content to be practical shut ins.
Why do you assume the government would be the one using artificial wombs?
The birth rates are not due to population density but to arkcyst theories
Every boss migrates to the Yaymans eventually
Have you played outer wilds?
The problem with this is as Isaac always points out about fermi solutions. It has to be true of all aliens.
What if going faster then the speed of Light has a negative effect like aging faster …
Right now in the Andromeda galaxy there is much older and more advanced society that has colonized hundreds of star systems around them. They only use low power energy efference light bulbs so humans will never be able to see them. At 2.5 million light years away they are able to see the earth and are debating if all those giant lizards are going to do anything in the future.
No. Watch the alien beacons episode and mega satellites.
Meanwhile, if I had everything I needed to mine and create tin foil, then I would have an unstoppable hat-making empire!
TY SFIA pre-emtpive comment before i even finish the video 👍
Interesting concept..tho I suspect vacation or pleasure worlds capable of supporting multi species organisms are going to be RARE.
Otherwise..exploration always is the vanguard for exploitation….
It'd take a billion years to develop the technology.
All of em migrated? Statiscally impossible
Yeah, aliens are trying to contact us, they saw Elon Musk floating by in his Tesla and said Where can I get one of those?
Be careful gathering so many brains in one place, you may attract zombies.
the evolution of life from nothingness may have not occurred anywhere else in the universe.
What if we're the first?
What if we become the "ancient powerful aliens"?
What if red shift is just artificial movement.
It's simulations all the way up.
They can run, but they cannot hide from the IA Algorithm …….and its missiles.
Drops a migration video right after the UK riots. Savage AF 😂😅😂😅
dont go to the 2nd dimension its a bit flat
Hi Isaac do you remember me
🎉
Love you Isaac!
I hope One day you will be seen as a prophet of sorts!.
