The Deep Future: Crash Course Big History #10

[@Clockworkcityofpain]

I BINGED-WATCHED CRASH COURSE BIG HISTORY AND I'VE REACHED A NEW LEVEL IN MY EXISTENCIAL CRISIS THAT I NEVER THOUGHT IT WOULD BE POSSIBLE

[@demianhaki7598]

+Camila Stefanie Welcome to being human :-D

[@FelipeFontesSPI]

+Camila Stefanie Great show! Sorry, but similar to "Big History" from Discovery Channel, both fail in predict the possibilities of the future, choosing one main flow as true, that we can call as "entrophy & expansion won". By the other side, actually the gravity bring us to organic life, and it's more probably that in 200-2.000 years human race can live without "organic life" keeping your conscious and creating a new society reflex of our current moral, values and needs. And this is the most probably to keep growing because even if the universe is so big and hostile, we're already here and playing a "single player game" that just depend on us to keep evolutiong. Once "humans" dont suffer organic limitations, and eternity lifes, we should spread this new kind of "super life" over universe, probably consuming materia from dead planets... and in a trilion-trilion-trilion years all over university should be populed with a huge diversity of "super inteligent god like" beings, that could eventually turn in to one or whatever. So, mixing a cientific-religion-moral weird stuff, we're a God that should rise in the future, in another time-space. Nice to think like this, we conect both faith and cience with a "most probably theory" as a method. What about "life after dead" that's something that we connect with God? I'm not sure, I don't believe it. But what I believe is in a future "transcendence" where the minds of the all human lifes can stay free in a virtual world totally conected and harmonic to the phisical world. Well, who knows? =)

[@kyledolor5257]

+Felipe Fontes You should improve on your english and your comprehension. I get what you are saying, but it has no order into it.

[@DaDunge]

+Camila Stefanie Been there done that. But do not fret a trillion years is a long time, we might hav emovied on from this universe by then. Well not us we'll be dead. and quite frankly humanity will have evolved to other thngs, but life descended from earth, and knowledge first created by humans may very well be preserved beyond that point.

[@DaDunge]

Not to mention that when humans are unraveling the mysteries universe we are really the universe itself taking the first stumbling steps towards sentience.

[@22steve5150]

In the end, the mongols will cease to be the exception.

[@JaimeNyx15]

Or will they...? EXTRADIMENSIONAL SPACE MONGOLS!!!

[@MatthewSmith-sz1yq]

The mongols colonized the moon, because they have to have been the exception, and the only nation to colonize another planetary body. Also, they will technically still remain the exception unfortunately, even after the end of humanity, just like how a pterodactyl had the largest wingspan of a living thing ever, despite the fact they no longer exist.

[@ScareSans]

never! the entire universe may cease to be, but the mongols will be the exeption!

[@rawhamburgerjoe]

Cue the mongoltage!

[@mikeor-]

Wait for it... the Mongols!

[@jbkjbk1999]

"What a lot of us overlook is that we are not just observers of the universe, we are the universe. We don't exist outside outside of the universe, we are indivisible from it, we are made of the same stuff, and in all of our transformations over billions of years from star-stuff, to single cells, to students, to one degree or another, at every stage, we've shared in that freedom of transformation, to flow endlessly from one form to another, and maybe we won't survive as individuals, maybe we won't survive as a species, but we will continue into the deep future. We are a tiny part of the universe, but we are a part of it, and from so simple a beginning in ways most beautiful and most wonderful, we the universe, have been, and are being, evolved. That ability, in fact, necessity, to change, is your birthright, acquired at your original birth thirteen point eight billion years ago and it can never be taken away. It can never be destroyed."

[@anythinginvolvingsharks]

"we are a tiny part of the universe, but we are part of it." i'm not crying, i just got some tears in my eyes.

[@elijahplummer3655]

You have a beautiful mind, drunk pikachu.

[@morgannightingale8094]

I can't believe I actually went to check...

[@mikerivera373]

It's ultimately more or less an attempt to disguise the fact that all life will die out and matter will decay into nothingness. Like I'm not just being pessimistic here, because I actually do have reason for hope. But in terms of the video, the monologue is more less made to help gloss over the fact that they just said that all will go to nothingness. That nothing here really matters in the slightest. I don't think it matters how you spin it, the monologue was essentially saying that it's okay that nothing matters, it doesn't have to matter. Which I don't find particularly comforting.

[@user-jd3fs3xj1y]

this episode made me feel rly emotional for some reason.

[@milenawittermans662]

Same

[@robertdicke7249]

don't worry, its normal. I felt the same way when my grand father started teaching me this at the age of 5. Now here's my question... should I pity or envy the seemingly infinite(but not really) number of people that had the potential to be born but never were not even getting so far as conception or even worse/better the children they might of had/passed up, or their potential children etc.?

[@nmsnerd]

Cue existential crisis.

[@Shilo-fc3xm]

You have been paying attention!

[@kendomyers]

How did your crisis go? Was it significant enough to remember 3 years later? Btw, the world sucks more today than it did in the summer of 2015, maybe you will want to go back to the past.

[@ChaseChaseChase]

I find this video to be good news. Even though I may die, which I probably will, my energy, my force, my material will forever live on into eternity. Who I was will die, but what i was made of will never cease.

[@santiago24601]

yeah, but it was never YOUR energy, force or material. it belonged to someone/something else before. being born is like going out of the biggest thrift shop ever.

[@mgibbs88]

Insert Name Here Your matter is constantly being replaced even as you live. Cells are constantly dying and replacing themselves. You are constantly consuming air, water, and food and having it enter your body. The molecules you have now are not the same as the molecules you had a decade ago. Your material was never yours to begin with, it consists of atoms that have existed billions of years ago and will exist billions of years after you are gone, they are just being used temporarily to form your body.

[@ManDudeYeah]

Xantiago P I love your brain. Keep speaking the truth.

[@mikerivera373]

NOVA let's be honest here. No one cares about their "matter." It's their "consciousness" that we care about. Now I'm a Christian. I believe that when we die, our "consciousness" (or as I call it, our souls) never ceases to exist. However, if you believe that your consciousness is tied to your matter, I hate to break it to you, but your consciousness will die when all of your matter dies. And if all matter dies, then all consciousness dies. Which is pretty bleak, empty and depressing. The monologue at the end more or less attempts to gloss over that, but when you internalize it, that's the end result you see from this.

[@midzyblinkonce7716]

Basically we’re all time lords. We regenerate when we die

I used to think of the end of the universe as really scary thing. Today, after seeing it explained by Hank, I somehow find it kinda beautiful. Thanks Hank.

[@therealcellar1969]

But there will ALWAYS be cake

[@EverettGuenther]

It would probably be so slow that it would be to boring to be scary, the end of the universe would slowly kill off people and planets instead of some apocalypse like explosive event.

[@crochetingcanuck]

SANITYSSHADOW69 I meant more the thought of the universe ceasing to exist was scary. I never thought therewould be an apocolypse like event.

[@thatsnotpudding]

[@Kaenif]

***** That is EXACTLY how I found consolation with the inevitability of a (though unimaginably distant) heat death, but somehow the hyperspace thing seems to me as an invented refuge out of the universe to make the story feasible. :P

[@EuropeanQoheleth]

This episode was deep. No pun intended.

[@danfrioli813]

Every time John has said "the universe is big, really big" in the course of this series, I've found myself expecting him to continue "you just wouldn't believe how vastly, hugely, mind-bogglingly big it is."

[@ivanchagasp]

This is one of the best videos you've ever done! Not only in terms of animations, but the script, content and way of delivering the message was really powerful! It really got me thinking about us, life, universe and everything else! :-) Thanks for being awesome, guys, and for remind us of doing so as well!

[@Thought-Cafe]

Ivan Chagas Thank you so much!

[@Kelvin6071]

So wait. If the universe is going to end one day then why are we still hating each other over meaningless things. Why do we separate each other with race, like if a person's skin tone have to do with it. Why don't we love each other and enjoy our lives, we only got one. One day the universe world end and humanity would be gone and nothing would've been remembered, not the racists, heroes, conservatives, liberals, etc.. no one.

[@Kobolds_in_a_trenchcoat]

well you can think of it like this your life and the lives of everyone you have ever met and ever will meet are already going to end and yet all of those people still have conflicts. not trying to be depressing but still.

[@hakairyu1]

From a perspective that envisions the universe, we don't matter and are a but a tiny speck of existence. From a perspective that envisions humanity, there are reasons for all that bullshit. Good reasons? No. Cynical but logical and plausible reasons? Yes. You can look from the greater and lesser perspectives and see how it affects us, how our base instincts and complex thought patterns are formed and operate and what their consequences will be. Hell, humanity can try to take control of what they understand, as a consequence thereof I'm currently hitting buttons on a keyboard that make a slight noise to relay you publicly this message. But after we've understood what we can from all that, to understand the ills and goods of humanity requires you to take all that information and apply it from a perspective that encompasses humanity.

[@Kelvin6071]

hakairyu1 good point!

[@Kobolds_in_a_trenchcoat]

***** vsauce made an episode on how its generally fairly safe to assume most if not all the predictions on how the future will turn out we have now are wrong. watch that episode according to it we are only doomed given our current understanding of science and most likely in a century or more or less we will have a better understanding and be far less doomed.

[@Kelvin6071]

***** No your right but as long as we're alive its important. (to us at least).

Pretty sure we could figure out hydrogen fusion very quickly. Just need big oil companies to stop getting in the way of progression

[@hammer0987654321]

I very much agree

[@cyanit42]

Hydrogenfusion was already done in laboratory conditions, but always at a loss of energy. Btw if you didn't know there is already a joint project underway to build a prototype fusion reactor (en.wikipedia.org/wiki/ITER). If this is successful there are plans already to build a prototype powerplant based on this design.

[@iluvDNA100]

This is what happened to poor old Tesla; his greatest ideas were shot down or stolen by the powers-that-be. We still don't have wireless electricity or earthquake generators.

[@LetsTakeWalk]

Joe Seph Wireless electricity is non-feasible with our current technology. Wifi, radio, bluetooth etc.. would not work with it (for the simple reason that Wifi,radio etc.. are already a form of very weak electricity).

[@deadasfak]

Hi! I'm an oil company CEO. I'd like to know how this hydrogen fusion thing works because if I'd be the first to bring it to the market I would destroy all my competitors. Cheers, Captain Obvious CEO of common sense oil inc.

[@CB-sk1pq]

10:31 "This, as far as we can tell, is the end of complexity as we know it," said Hank, smiling happily...

[@issy1386]

does anyone else think that these two will be in history and science textbooks in a while? I think they are both brilliant minds who really deserve it.

[@tesseraph]

This was one of the best videos John and Hank have (by any degree of involvement) made: from Hank's discreet Bilbo quote to John's "We ARE the Universe", this had chills going down my spine. You guys are amazing. Big History is the history for me

[@CezarMS1]

I absolutely love how this show walks the line between science and philosphy... they are definitely one and the same.

[@rachelaleishoppe5928]

I love this series. It's so interesting and it feels good that I'm learning stuff over summer vacation. Thanks John and Hank!

[@joseescobar3703]

Thank you so, so much to everyone involved in the making of this series! This last episode got me so emotional, and after "taking" this course my perspective of life has fully changed. Thank you so much!

[@chasing6]

"We, the Universe, have been - and are being - evolved." One of the most well put and beautiful sentiments I've ever had the pleasure of hearing on the internet. Particularly the first three word. Thank you, Brothers Green

[@gabrielleregimbal7419]

I love the effort that goes into these videos. The quality makes the viewing drastically more enjoyable.

[@slykeren8371]

this stuff makes my stomach churn

[@noirneko9697]

Thank you! I really enjoyed watching the two of you record a show together. I found the topic profoundly deep and learned a lot.

[@FanOfAr]

Regardless of whether or not the specific information in this is right or wrong (because who's to say what we might discover tomorrow that'll throw all our current predictions out the window?), your perspective on and appreciation of this magnificent universe is incredible and contagious. I think/believe/hope it'll catch-on throughout our species, become our springboard out of this bottleneck, and bring humanity to its fullest potential...which potential, at this point, is simply unimaginable to any of us. Thank you for making these!

[@mynameismatt2010]

Grr, Heat death. I hate that theory so much. I really like the big crunch theory way more. I mean, we don't know that dark energy will continue to accelerate the universe forever. We look and see it happening now, but we don't even know why it happens, it could just be being fueled by the energy of the big bang that exists in a dimensional "higher plane." Eventually that energy will dissipate and gravity will be the dominating interstellar force once again.

[@Randomgen77]

#TeamGravity

[@showbusiness5844]

There's so much to learn about the universe that these three theories will be jokes in the future.

[@nathankristian7775]

It doesn't matter which theory you like or do not like, the heat death theory is more likely to occur based on our current knowledge. This doesn't mean that it will happen but it seems to be the most likely candidate. Additionally, the universe isn't just expanding, it's expanding at a fast and growing rate due to the density of dark energy throughout the universe being a cosmological constant which means that as the universe expands, dark energy will not be diluted like the forms of matter. This is why the heat death is more widely accepted, because it's aspects are able to match our findings better

[@mynameismatt2010]

Nathan Kristian Yeah I know all that, but a guy can dream. Heat death is so much more depressing than any other theory. It's the ultimate expiration of everything as an absolute inevitability. No cyclical continuation, no lone survivor style civilization using technology to outlive the rest of the universe, not even a definite moment of passing the "too cold" boundary. The worst part for me is probably that time carries on after there is nothing for it to interact with. Even after heat death, the universe doesn't cease.

[@IceMetalPunk]

mynameismatt2010 You're missing the beauty, though! Our universe started from nothingness, and it will return to nothingness. This is almost certain. But there is no reason another universe couldn't start somewhere else (if you're going with "might happen despite no current evidence" hypotheses anyway)! In fact, there's no reason other universes aren't starting elsewhere ALL the time! So while we will die out, another universe will be just born, with its whole, big history life ahead of it :)

[@djnAbNo2]

That was a very comforting piece of consolation at the end, John. I was beginning to feel sad about our fate but that was very uplifting. It is a very profound realisation and truth indeed that, our age is not the time lapsed since we left our mothers womb, but the very age of the universe itself. We are composed of the building blocks of matter, we are the same as everything single thing on our planet and the cosmos, just in a different arrangement and order. This notion helps me understand, as an aside, what the study of Mathematics is about. The science of patterns, some call it; think that in terms of matter we are identical to every other single object in the world. It makes the miracle that is life even more astonishing, that these building blocks could somehow arrange themselves in a way and allow energy to transform them into animate objects. You realise what we basically are right? It's identical to how passing current, electrons that is with kinetic energy, through some system that we designed with certain mechanisms, patterns and orders gets the clockwork moving, causing it to come to life. The miracle of life is truly mind blowing.

[@devinbeverage5199]

Whenever I consider that ultimately the universe will cease to exist (as unfathomable as that is to start with, the earth will go first) I can’t help but have the simple/silly thought, “Wait, if everything that ever has existed is just going to end up ceasing to exist, why does anyone bother to do anything... ever?” The reality is that we are present here and now, and actually doing things makes our existence interesting and (hopefully) better, but it’s easy to look over everything mentally and contemplate that potentially everything that has ever existed and ever will exist could all just be pointless. But then again... No one ever said there was a point.

This is so far my most fave Crash Course episode. Jean Houston's lessons reminded me so much of this episode. "You are not just in the Universe, the Universe is in you."

+One Thou Wou I'd have to disagree with you there. The idea of a parent is a separation at birth, some level if dissociation that separates parent from child.

The universe wouldn't be the same universe without us, and we wouldn't be without the universe.

You guys are awesome and for real the philosophy that me, is part of an always changing universe, that nothing can really be called bad or good but everything evolves has changed my life a year back. Being able to see things as a hole and being proud to be part of something so AMAZING that the long story of the universe is. On my own I am just an atom alone, which can be called useless by haters but I do know that with other atoms we can form more complex things. It made me realize how awesome life is, how incredible it is to be part of a constant evolution and what is important in life. No life is useless, no life is useful, it is just life, always changing like the universe and it is up to you to enjoy that experience or deny it... Thanks guys, you are heroes to me.

@@victorvelie3980 I mean, when life consisted only of bacteria like 3 billion years ago, those lifeforms wouldn't have been able to even dream of doing basic math, let alone doing something more complex like changing the surface of the Earth or reaching space. But now, not only have we done all three of them, we're also beginning to understand our biology enough to make bioengineering a thing, have discovered elementary particles and quantum physics, and then there's other upcoming fields that'll change us on such a scale that human a few centuries earlier would probably view those inventions as impossible.

Thanks for being awesome, mr. Green. I see you next week

[@miguelespinosa3870]

Thank you Crash course! just done with all the History series, awesome stuff.

[@phoeniciandiaspora4584]

How am i able to even think about the whole idea of existence? Everything is built on nothing but what is nothing? what happened before nothing, it has to be impossible for their to be nothing without something, I'm sure nothing has to be made of something or else it wouldn't even be able to be thought about? I'm not trying to doubt the big bang or anything but its crazy to think about thinking about it. It is all too much for my young feeble 12 year old mind to understand, and that brings an ever lurking shadow of amazement that will never be quenched. existence is an enigma that will never be solved, no matter what. it all sends a chill down my spine :[

[@IceMetalPunk]

"Before nothing" is a meaningless statement in this context. The Big Bang brought time along with space; there was no time until the Bang. So there was no "before the Big Bang", only after it. And also, why can't we think about nothing even if it's not made of something? These are abstract thoughts, they need not be entirely bounded by physical restrictions.

[@phoeniciandiaspora4584]

IceMetalPunk thanks for the answer

[@Survivorman72199]

IceMetalPunk Really there is no time at all. Time is just something created by humans to help understand what is going on around us. The only reason why time exists is because matter exists in our universe. If there was no matter, there would be no time. Things would just start happening and stop happening with any comprehension of when they did.

[@IceMetalPunk]

Survivorman72199 Not...really. Time is a dimension, just like the (x, y, z) dimensions of space. That means an event--i.e. anything that happens--requires a time coordinate in order to uniquely distinguish it from any other event. For example, if I say "meet me at the building on 42nd street", we probably won't meet each other. Because you only have one dimension, the street, which let's align to our X axis. You might show up at 42nd street and 5th avenue, while I show up at 42nd street and 30th avenue, and we are now having two different events. In order to specify a specific event unambiguously, we need more than one axis, then. So what if I say, "Meet me at the building on 42nd street and 30th avenue"? Now we have an X and a Y axis, two dimensions! Okay, good... we both end up at the same building this time... but we still might not meet, because I could be on the third floor while you're on the tenth floor. Uh-oh! I still haven't described the "meeting" event uniquely! Clearly, we need more dimensions. So now if I say, "Meet me on the third floor of the building on 42nd street and 30th avenue", does that fix things? I mean, we have an X, Y, and Z axis, so we're now in the same building, on the same floor...things are good, right? Well... not if I show up there today at 5:00 and you show up there tomorrow at 10:30! Our meeting, as an event, has still not been specified uniquely! There are MANY events that take place on the third floor of the building on 42nd street and 30th avenue! Last week, there may have been an advertising convention there, and yesterday, maybe there was a hackathon! But neither of those are our meeting. We've given three spatial dimensions, and yet we STILL have not defined our meeting uniquely! So we add a fourth dimension, time, which is only temporal because certain physical laws don't work the same if you reverse time (whereas reversing spatial motion leaves them intact). So now I say, "Meet me at exactly 5AM on the third floor of the building on 42nd street and 30th avenue." And NOW there's no way that we don't meet up; our meeting has been unambiguously defined only after 4 dimensions: (x, y, z, t). (Before you say "but other things can happen on the third floor at that time!", this was an example which used very vague coordinates along each axis; if instead we defined them numerically and precisely, there could be no ambiguity in the event description in 4 dimensions, but no matter how precisely we define it, using 3 or fewer dimensions ALWAYS leaves multiple possible events.)

[@Survivorman72199]

This is very true; I hadn't thought about the fourth dimension until you mentioned it. What I meant is that humans were the ones to put numbers with time. Just as we have come up with measurements of distance for use with the x, y, and z coordinates, we have come up with measurements to put a number value with time. Either way, if the universe had not been created, there would be no fourth dimension due to there being no laws of nature in the first place.

[@nickynak3]

I dislike the thought of a pill that provides us with all the nutrients etc. that we'd need, eliminating the need for food. Food is tasty and enjoyable to eat - why would I want to give that up? Well, a lot of it is, anyway.

[@IceMetalPunk]

That's the problem with Soylent.

[@chillsahoy2640]

Presumably, food would become a luxury item, or something for special occasions. As long as we have a physiology and mental framework that interprets food as desirable, there will be a demand for food, because it tastes good. Even in the present, eating isn't just done for nutrition and pleasure: we also eat socially. If we ever come up with a nutrient pill, it will eliminate the _need_ for food, but it probably won't eliminate eating practices, they'll just become a special occasion.

[@PanicbyExample]

but compare it to situations where people eat so much junk or can't afford to eat anything at all. or even consider how hard it is to eat a fully balanced diet. you could eat a pill that would have you covered then you can eat the food you want just taking into account the caloric intake. i've never understood people's kind of uniform beef with soylent, wherefore yo, IceMetalPunk ? not bitching just wondering if it's sort of a long-range 'this'll lead to chaos' or if it's just unmarketable the way you see it

[@Mega3rn3st]

I only eat food for energy.

[@foobargorch]

in the future there will also be a pill that gives you hyperbulimia

You're the most beautiful thing I've ever heard.

[@UltraGoldenCow]

That's a pretty comforting thought actually, that we know the universe has an end date, it makes me feel slightly better about the things i'm going to miss, knowing that there is an actual limit to the things I actually CAN miss.

I'm in the big history class, everything that is taught is so thought provoking!

[@inkajoo]

christ this shit is so depressing to me and i can't stop being fascinated by it

[@NightDoge]

Depressing? I find it incredibly, amazingly, gloriously, beautiful! Numinous even, And yes, endlessly fascinating.

[@inkajoo]

why's it depressing? because the vast majority of the universe is not full of anything remotely similar to us. and we're only going to exist for a blip in the grand scheme of things. and the fact that we're an accident.

[@confusedflourbeetle4734]

What if we somehow travel to another universe and keep universe hopping?

[@toplt2782]

That's when we become god-like (unlikely), if we ever do, because obiusly that would be another species. Let's say there're other universes, those ones most likely have different physical laws, so in this scenarios we can't tell how matter and energy from here would behave there.

[@nfnmrm9652]

The last remarks were great. Filled me with joy Thanks

[@colerockyhorror8959]

the ending was such a true moment to me, i really understood what john was saying and i agree 100%. I just wish that would people strive to learn more about this topic because it truly shows how we are all the same.

[@minervaalexia6074]

This was a... rather somber end to the series, even with John's speech about energy transformation. I... I really don't want to die. I hope that we can get immortality, either through transhumanism or through stopping aging. I don't want to just cease to be. And I don't want things to end.

[@NachoTPAO]

But... you will still have that "Head Death" problem at the very end :P

[@LuisSierra42]

Immortality is boring

[@TheSimonvdp]

If you're immortal, in a sense that your existence will never end, you will eventually experience everything. Everything.

[@LuisSierra42]

like for example in The Groundhog Day movie

[@Shilo-fc3xm]

Often the older you get the less you worry. Not always the case of course but if you live a good life and have the depth and take the time to absorb the meaning and lessons in the earth and universe around you the more at ease you become.

[@Dyslexic-Artist-Theory-on-Time]

Within an infinite Universe we have an infinity of possibilities for life!!!

[@ShadowFox178]

But the arrow of time has no mercy and will lead everything down to a similar massless future. Your argument can only be made for the present. Plus with no chance to see the multiverse but to speculate on its existence makes it almost completely redundant.

[@OddMartin]

Woa, had my pretty powerful earbuds in my ears during Johns intro. I got goosebumps down my back because of the bassss

[@IceSick88]

Wow guys..This is the best video you guys have ever made in my opinion. A perfect ending to an AMAZING video series.

[@jesuschacon1632]

John kinda sounds like Seth Rogen

[@jesuschacon1632]

like an octave higher...

[@wedgewizard5429]

Wouldn't it be crazy if the earth was destroyed in the future, and the human race went extinct, but tardigrades that were clinging to the space debris that was out planet expanded out in every direction and colonized a few habitable planets and evolved new species of aliens that actually shared DNA with humans?

[@mannyaustinanderson9608]

we'll probably end up discovering the technology to produce our own stars before the 'end' of the universe happens. And we'll most likely find a way to travel faster, or more efficiently, than the speed of light.

[@BobBob-dc9bk]

technicaly "we" wont egsist in a similar form when we will actually care about the end of the universe

[@mannyaustinanderson9608]

Maybe

[@okuno54]

I do have hopes for FTL, but at some point, the universe is going to run out of elements light enough to build stars out of, natural or artificial, because those stars will have converted all the atoms into iron. The only way complexity escapes eventual death is if we find a way around the second law of thermodynamics, which is pretty tough, because it's more statistics than science in a way.

[@vualgrimoire4822]

What's this "we" stuff? 99.9% of alleged humans are parasites on this world who do little but suck up resources and oxygen. "We" will kill off this planet and ourselves, hopefully long before we go out into the solar system to make a mess of other worlds.

[@mannyaustinanderson9608]

vual grimoire very cynical. Many humans play a positive role in our development. Instead of fixating all your attention on what you hate about humanity how about you start contemplating about the positives? Of course, your definition of positive may be completely different from my own

[@akmalsy159]

Personally I found solace in doing things that make a difference, preferably a good one. It may not be a big or even long lasting one but as long as the fact I exist causes something else good to happen it's good enough for me. Also even if this universe dies, I also found solace in the fact that it existed at all. The Big Bang happened and its result is you and me. I'd like to think the new Universe born from the new Big Bang will also have beings like us that will continue this train of thought even if the idea of "us" ceases to exist. P.s. whatever happened to the Big Crunch theory?

[@flaviusclaudius7510]

The Big Crunch has largely fallen out of favour with the discovery of the acceleration of the expansion of the Universe. While it's still considered a possibility, the range of parameters for which it works is very narrow and possibly unphysical.
