technically it's possible to detect the neutrino emission that effectively reaches earth at the speed of light, before gamma does. You can trace the neutrinos back to the source star and check if its axis of rotation intersects with us. Then you can do the math for how long earth has left

[@SouthernGothicYT]

I think that since the universe started off being unpredictable and violent, it's getting to be more stable, we're just one of the early civilizations, so that may be why we don't see other signs of intelligence. Perhaps the history of the universe parallels human history: a chaotic formation, years and years of developing, sudden explosion of life, then the dawn of intelligent life. We're like the dawn of civilization of the universe in this analogy.

[@MostHighEmperorPalpatine]

Michael Scofield that moment when you try to be a grammar Nazi but fail cause no bodi cares about grammar on utube...

[@deldarel]

By being late we actually have a pretty big advantage: there are a lot of heavy elements on earth and many of them really make our life easier. Also, life evolved extremely quickly on earth. What if we're only twice as fast as the average? That would mean that the average would occur once the planet is getting hostile. And size. The vast majority of animals is extremely small. What if most intelligent life is just not big enough to propel itself into space? What if it's so small that it has no desire to colonise other planets because they couldn't overflow the planet in a billion years anyway? What if evolution prefers brawl over brain and we're the exception? Like, imagine the early humans with the dinosaurs, how much of a chance would we have? The biggest we had to fight off were wooly mamoths, which are relatively docile creatures. Then there is the fact that light is extremely slow on a cosmic scale. The biggest chance there is is that there is plenty of intelligent life in the universe colonising other planets, but that they are simply outside of our observable universe, not in space but in time. Finally, let's look on earth. How many animals can we consider intelligent life forms? 1: humans. Even within the millions of animals on earth in the billions of years they've been around, only one can be considered intelligent. This tells us something about the odds of intelligent life coming from life forms in general. The problem is that we cannot compare our results with other systems. This is our biggest problem with both extraterrestial evolution and the fermi paradox: our sample size is 1.

[@bobsmithy3103]

RIP Harambe

[@jmitterii2]

For those reasons you mentioned: I don't think we're "late". I think we're the earliest such technological creatures could exist.

[@bartvansoest2492]

Very interesting reasons you mention for intelligent life to be unlikely to develop. I feel like the existence of sexual reproduction also speeded up evolution on earth a lot and might be very unlikely to develop on other planets.

[@bartvansoest2492]

I don't believe Gamma Ray Bursts are the answer to the Fermi Paradox: It took humans roughly 200.000 years to get where we are, or 6 million years if we count since we split from the apes. We will probably be able to leave our solar system in another 1.000 years. But even if it takes us another 100.000 years, it doesn't matter in this case. At the other hand, we know life on earth hasn't been whiped out by a Gamma Ray Burst in the last 450 million years. At least not since the dinosaurs died 65 million years ago. So if (our form of) intelligent life needs a couple million years to escape our solar system and Gamma Ray Bursts hit a planet less than every 100 million years, plenty of civilisations should be able to spread far enough from their home planet not to be completely whiped out when a Gamma Ray Burst strikes its home planet.

[@gbrown932]

I enjoy the humor you inject into your videos. I'm a big fan of how the universe works and your channel is very informative.

[@Thaidory]

The most plausible explanations is that we look for civilizations that are of our type. The one that uses radiocommunications and harnesses energy with some Dyson Sphere like megastructures. What if this is just a relatively short stage on a civilization development timeline? What if advances in quantum physics or string theory will move us beyond radio and electronics just as we moved from bonfires and horses? What if civilizations that moved to that level already are fully aware of our existence, but they just care about us no more then we care about ants in a rainforest? Then Fermi Paradox is not a paradox. It's just another result of our attempt to extrapolate our own history from the age of geographical discoveries to space. It just doesn't work the same way.

[@Sir_Budginton]

I read an article saying how intelligent life couldn't exist before now because in the past most stars were much larger and therefore shorter lived, not leaving enough time for complex life to develop. Also Kees in mind the nearest galaxy other than our own is 2.5 billion light years away, so detecting life there would had to have developed at least 2.5 billion years before us which as I said above is unlikely The only place we could detect life right now is in our own galaxy which, when you take out 99.9% of all galaxies makes the Fermi paradox much more reasonable At least that's my opinion

[@sokaries682]

Hanif Shakiba millions, not billions

[@theeccentricwriter4657]

Hanif Shakiba Still the universe is Behemoth, there still might be many civilizations developing beside us Millions of light years away. But I feel we might be close to the first contact right now, Tabby's Star is showing us signs of a Kardeshev Type 2 civilization at least

[@AL-SH]

Hanif Shakiba Your opinion contradicts with reality. First off, the nearest MAJOR galaxy is called Andromeda or the M31, and is 2.5 million light years from earth. There are other smaller galaxies closer to Milky Way but they don't have enough heavy elements like hydrogen and helium, and both are essential for originating life. The M31 Galaxy, however, has enough heavy elements, and is known to have twice the amount of stars than our very own Milky Way. So, yea, there are possibilities that life, whether complex or single cell, could exist much closer to the earth than we had imagined.

[@MrTallCoin]

But Hydrogen and Helium are the two lightest elements, hydrogen being the base fuel of every star...

[@AL-SH]

[@kradrol]

I have a solution to the fermi paradox. "why the hell would an advanced civilization that can travel across the universe communicate with radio waves?" also "if we don't even know for sure how many planets are in our own solar system, then we would we assume our technology is anywhere near advanced enough to detect evidence of a space-faring civilization?" this would be akin to someone from a small tribal island concluding that the rest of the globe must be uninhabited because they don't see the united states sending carrier pigeons across the atlantic ocean with messages for our allies in isreal. the notion of using carrier pigeons to relay messages then you satellite phones is absurd. so why do we assume that an interstellar empire would communicate with each other using technology that we stopped using before the turn of the century? in other words "we lack the sufficient technology to perform an adequate search for intelligent life." or if you prefer "we too dumb to find aliens."

[@jacobhu4431]

kradrol . Well in the beggining there were about 19 but collisions and runaway planets AND DWARF PLANETS make it so 8 right? Or was it 9 IF u include Pluto still.

[@jacobhu4431]

kradrol . Still you make a great point that is also a solution to Dat paradox.

[@alexb8433]

I feel like one day a big ships gonna come and say that are planets gonna be destroyed to make way for a interstellar highway

[@fotisbouzas9161]

For a civilisation to grow so advanced surely they had to go through the phase of emitting radio waves tho, right? And those radio waves may still travel through spacetime even tho a civilisation may have already outgrow them. Right now we've emitted radio waves that still travel through the cosmos. If we develop technology that doesn't emit radio waves anymore, the ones we've produced will continue going forward. Shouldn't we by this point have caught something eerie then?

I present a new theory: Every planet with life on it has to pass two tests--it has to give rise to a species intelligent enough to create a doomsday weapon, and that species then has to be wise enough not to annihilate itself with said weapon. So far we seem to have passed both tests, but there's no telling how many races there are out there that weren't so lucky--perhaps there were once Venusians or Martians or even Jovians, and what we see of those planets today is the result of a great thermonuclear war in the distant past.

The way I answer the Fermi Paradox is this: We took over 3 billion years to evolve, and for 2 billion years of that we were single-celled organisms. If a freak accident hadn't have happened 66 million years ago the dinosaurs would still be roaming the Earth. The conditions for life on our intelligence level have to be precise and exact and take billions of years to happen. We are here because of pure luck. Had that asteroid missed? We wouldn't be here. Had synapsids not evolved back in the Permian? We wouldn't be here. Had whatever caused the first Earthly life form to appear (which probably has a trillion or more to one chance of happening in nature) not have happened? We wouldn't be here. We owe our existence to chance and chance alone. Yes, life may be plentiful in the universe. But how much of it is single-celled organisms and thus currently undetectable? Probably over 99% of it. How much of it is on our intelligence level? Quite possibly 0% apart from us. If there is other sapien-level intelligent life out there, it's probably much too far away for us to be able to ever detect, let alone interact with. As I said, 99% or more of life in the universe is single-celled, bacteria-like life forms.

[@lum26akua28]

Sawk Video Productions But, there is just so much within that 1% that we ought to have seen something by now, even with those problems. There has to be another explanation. And, yes, I do believe that we aren't alone.

Best argument for a really well-funded space program I've ever heard--we need to gain at least a hundred light-years distance from our home yesterday.

When I listen to Primus' Extinction Burst I always imagine some massive star out there, spinning several thousand times faster than it's meant to, blasting out GRBs to the music, slaughtering everything within a galaxy cluster.

[@randomcommenter395]

Hater: this is trash I disliked Fan: you should have a second thought about that

[@RealRayGun]

Very cool, im gay

[@MrDylsha]

same

[@Posts_Comments]

Do the gay.

[@sudonim7552]

Me too thanks

[@flarfo348]

Reasons I love this channel 1. They have a personality unlike a lot of other science channels. 2. They watch other KZbin videos (the alien was watching the history of the entire universe i guess) 3. SPACE COW 🐮!!

[@zuryaabiqbal3062]

Hey dude good job on making good content keep it up really enjoying myself and your vids!👌

[@NovaMenno]

1:58 I did not expect History Of The World to be in this video, now I can die in peace.

Here's my answer: Quantum Entanglement and Gravitational Waves. Basically, any civilization capable of interstellar travel - even if they used slow generational ships - would require a communications network that's faster than radio waves to hold their society together. If they were capable of even light speed travel they would either use something else, or just mail letters since there's no point. Humans, as it turns out, have the technology to send information via quantum entanglement - dubbed "Quantum Teleportation" - which allows instant communication from one point to another without regard for distance. While the lab range is still limited, the theoretical range is infinite and there would be no way to intercept the communication since it doesn't pass between points at all, but rather uses "spooky action at a distance" so if a civilization fully developed this tech radio waves would be obsolete. There could be a galactic internet all around us and we'd never know. It's likely that every civilization would make some noise briefly then go silent without actually disappearing. Now, as far as travel goes, it's not impossible to travel at the speed of light. It's just difficult. Gravitational waves are creates whenever two objects with mass move around each other, so just typing on this keyboard creates gravitational waves - reverberations in space time moving at the speed of light - and these reverberations are so weak they are unable to interact with matter or even be detected. However, when black holes collide, they create a large enough ripple for us to listen in billions of light years away. It's unknown if these waves would be strong enough at the point of origin to push matter, but it likely is, meaning that matter is pushed via natural warp field at the speed of light until the wave spreads out too much to carry the matter. Then it stops abruptly having experienced no affect from speed since it technically wasn't moving at all - space was. Since exotic matter is not required to create a gravitational wave, just an object of any mass moving fast enough, it really comes down to finding something that won't rip apart. We can create machines that could theoretically create small gravitational waves capable of moving objects if only we could find a material that can handle it. So suppose a civilization could do this: They could create what I call a gravitational wave cannon capable of launching an object in one direction at the speed of light, but without any time dilation effects or issues with weight. As an added bonus, it could project a wave in front of the craft to push anything away that might hit it, and long after the wave is no longer able to push the craft it could still push debris further protecting the craft. You'd just need a focused wave strong enough, calculating everything precisely so not to undershoot or overshoot, and you could send a ship to Alpha Centauri. It would just take a little over 4 years. Taking things a step further, if you could minimize this tech you could create an array of gravitational wave projectors that are individually weaker, but can coordinate via acoustic holography to create complex geometric shapes to shield a craft, act as a tractor beam, or move the craft in any direction with impossible maneuverability. Interestingly, a flying saucer design would actually be very good for this with the projectors around the rim, and it would likely want the ring to move independently of it making it look like it's spinning. It would not be built for aerodynamics, but it might appear that way. Taking it even further, you could use this tech to protect a planet from an asteroid, or destroy any nation you wish, or build a Dyson sphere. The only issue being that a suitable source of energy is required. Now, if you want to actually detect aliens, you don't want to look for radio waves. Rather, you want to look for weak gravitational waves - far weaker (because they are focused) than anything a black hole would come up with, and so far humans can only detect those. UPDATE: Gravitational waves are strong enough to eject super massive black holes from the center of galaxies! So we have observations yo support the hypothesis that gravitational waves can move a craft at the speed of light, but it won't likely stop immediately when the waves weaken so you'd probably have a problem being launched via cannon. www.nasa.gov/feature/goddard/2017/gravitational-wave-kicks-monster-black-hole-out-of-galactic-core

More videos on fermi paradox please. This is such a facinating paradox.

[@LordAJ12345]

"If the universe is teeming with aliens... where is everybody?" is a pretty interesting book on this subject. It goes through 50 different possible solutions to the Fermi paradox, ranging from likely to absurd.

[@jbkid202]

Love your content, thanks for making such awesome videos. You asked for suggestions on other answers to the Fermi paradox, please do one on the great filter! Thanks

[@tigertail6941]

Can you do more on this topics? Like possible solutions to the fermi paradox?

[@firecat6666]

I had to light a cigarette when the guy started eating sand. jesus, that brought back some distressing memories from my childhood

[@Fkidd702]

Wow. Never heard of this paradox. Awesome video!

[@miels63]

1:29 poor guy.... He ate sand. Why do you even do that?? 😂😂😂

[@ballin925]

The best part about the question of whether or not there is other intelligent life somewhere in the universe is that either way.... both answers are mind blowing and amazing. If YES there is then that would be incredible to see what an entirely different species of intelligence would look like and what they would be capable of and what technology they would possess. If NO there is not. how crazy to think that with the unfathomable size of the universe we would be the only intelligent life on this tiny spec of nothing called earth in relation to the size of space. We would really be something special and how lucky we are to be here.

[@mehultanwar7823]

Good job, would love to see other videos about Fermi paradox

[@evanfunk7335]

"Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us." Calvin and Hobbes. What about that

[@rgfella]

I don't like when people say stuff like, "fraction of a fraction." It's like saying "forever, and ever, and ever" it's a misleading misnomer. Especially when stress is put on the last one in the sequence, making the specific amount seem relevant to the meaning of the sentence, when it's really just used for emphasis. Don't get me wrong though, I love second thought, and it's not like this even came close to ruining the video for me. Keep up the good work!

[@BriefNerdOriginal]

First of all, thank you for this good video. I'd really like a follow-up, but with more quantitative information (drake formula, probabilities, distances, space traveling constraints, etc.). Thanks!

[@mustafaemrebasaran7701]

Amazing video. Keep up the good work.

[@GandhiBoys]

Super awesome video, truly. Thank you.

[@nice683]

Nice videos. Keep up the good work. And I appericiate the work put in your videos :)

[@joshuasalem5022]

I always looked at this paradox as this: Spaces between planets, let alone galaxies, is just too vast. The chances of even the most advanced civilizations contacting the exact point of earth is basically none. They'd have to search the galaxy so meticulously, even at faster than light travel, that the odds of finding us is incredibly rare

[@liverpoolzul]

i'd like to thank Squarespace for sponsoring this video too.

[@kirbymarchbarcena]

There's no way we could reach those other galaxies that move away from the Milky Way even if we make technologies that could go beyond the speed of light.

[@Johnnyboi-jm5rx]

The animations really make it far more enjoyable to watch

[@quotebot0931]

Beautiful ambient music used in the background excellent taste

[@valentinofilipovic3297]

please more on this topic, this is great

[@noahb6955]

1:59 to the right of the alien ''THE SUN IS A DEADLY LAZER''

[@huffpappy]

The crazy thing is we would never see a killer GRB coming, and it wouldn't make any difference even if we did.

[@adammf9624]

Nice video man, keep it up!

[@Crusaderjack]

Everytime I watch like these really cool space videos it makes me want to play stellaris :D
