The universe is vast and full of nothing...
Which in case of explodey stars is a very good thing indeed!
- subscribed 1y agoIt's fun to think that at some point it will be actually vast and completely dark

- Obscurity4340 1y agoReally incredible video, thanks a quadrillion
- rbanffy 1y agoWe have a couple trillion years to figure out a way to fix that.
- frainfreeze 1y agoDoes it need fixing?
- rbanffy 1y agoSince I'd like to live forever, then yes.
- db48x 1y agoWhat you really want to do is put out the stars sooner then, and feed all the hydrogen into the supermassive black hole at the center of the galaxy. Dump in all the mass in the galaxy and all of its satellites and everything from Andromeda and its satellites too and it will grow. Nudge Andromeda’s central black hole into orbit around ours so that they merge, etc, etc. Grow it big enough and and you can build a Birch World around it, with a surface area larger than all the planets in those galaxies put together. All of the exploration with none of the boring travel in between interesting places! You can seed it with life from every planet your civilization ever encountered and watch all those ecosystems compete and hybridize as you while away the years. How many years would you have? While dumping matter into a black hole destroys the matter, it doesn’t destroy the mass. It just confines all of the mass in one place. Powering your Birch World is just a matter of using the Penrose process to extract energy from the black hole for the next few million trillion trillion trillion trillion trillion trillion trillion years (about 3×10¹⁰⁴ years give or take a few). The stars will only last for about a million trillion years (10²⁰ years plus or minus a bit), so this plan extends your your lifetime by a factor of a trillion trillion trillion trillion trillion trillion years. Maximal extension perhaps, but not quite forever. Forever takes a lot more work.
- mietek 1y agoI would like to hear what you have to say about forever.
- lazide 1y agoI imagine step 1 will be figuring out a way to reverse entropy?
- rbanffy 1y agoSomething about there being light, IIRC.
- db48x 1y agoThat’s actually [the _last_ question](https://users.ece.cmu.edu/~gamvrosi/thelastq.html https://users.ece.cmu.edu/~gamvrosi/thelastq.html), not the first. I liked the DS9 episode where the mutants realized that the universe was collapsing into the Big Crunch, so they demanded “antigravity generators, lots of them!” Their cosmology was wrong, but only because the show had the misfortune to be written in the past. Their enthusiasm was great :)

- 8fingerlouie 1y agoTechnically you can live forever in a universe that is completely empty, it'll just be a lot of cold dark nothing for eternity. Living forever is such a strange desire, considering that complex life has existed on earth for just a fraction of the time it has existed, and humanity even less than that. I recommend watching the Kurtzgesagt video called All of History in one hour (https://www.youtube.com/watch?v=S7TUe5w6RHo&t=3670s https://www.youtube.com/watch?v=S7TUe5w6RHo&t=3670s). It displays all of earths history in one hour, and humanity is merely a few seconds of it. Earth is ~4.5 billion years old, that's 4500000000 years, and in 1300000000 years it will be uninhabitable by humans, and in another 4.5 billion years (roughly 3.2 billion years after becoming uninhabitable) it will be engulfed by the sun. Assuming humanity manages interstellar space flight you could possibly escape earth and live somewhere else until that also dies, but in case it is not practical or possible, you get to enjoy 3.2 billion years of literally choking and being burned alive on earth. Assuming you did escape earth (or you're immortal so escaping doesn't matter) In 1000000000000 years the last star will be born, and in 100000000000000 years the last star will die out. You now have an extremely long time to enjoy suffocating in hard vacuum with your body being boiled by the low pressure, and all in complete darkness until the heat death of the universe occurs in roughly 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 years
- the_af 1y agoThe Cosmos (both Sagan and Tyson's) shows also display the tiny fraction of life in the history of the universe with their "Cosmic Calendar".
- amelius 1y agoAre you sure? At some point you have heard every possible joke that can be told in a timeframe of 10 minutes, 1000 times.
- Wobbles42 1y agoIt's very unlikely that I am capable of remembering every single joke that can be told in a timeframe of 10 minutes. If you were to take every such joke in a random order and put that on a loop, the experience would likely be one of perpetual novelty, even if you repeated it 1000 times.
- amelius 1y agoHow about: every day there is a small but finite probability that you fall into a deep pit, and it may take years before people find you.

- Wobbles42 1y agoI have to imagine that very few people would make statements like this if we lived in a universe where there was any real danger of it happening. It would be interesting to talk to humans that have lived even a few hundred subjective years, if any existed. That seems to be enough time to lead to very different perspectives on something like immortality. Given the information storage constraints of our minds, I wonder if there is even some age that makes immortality subjectively different than very long life. We don't seem to be capable of remembering even a full decade of experience. By the time you reach a few hundred years of age, would you have any memories at all of your first century? You might not have experienced a single "death" event, but the "you" that was born may have long since died.
- loloquwowndueo 1y agoWe don’t need to fix that, do we? Just let it be. You’ll be long dead anyway.
- h4ck_th3_pl4n3t 1y ago> We don’t need to fix that, do we? Just let it be. You’ll be long dead anyway. Spotted the republican
- selectnull 1y agoI guess even a republican can be right?
- h4ck_th3_pl4n3t 1y ago/dev/random is right sometimes, too.
- selectnull 1y agoIf you ask someone "What is 2+2?" and they answer 4, you can say they are "right" even if you do not agree with them on other topics or generally dislike them. If you ask /dev/random "What is 2+2?", that question makes no sense as /dev/random does not listen to you and just spits out random binary output. Go and disagree with /dev/random.
- h4ck_th3_pl4n3t 1y agoMy point that you successfully explained and intentionally ignored is also: /dev/random ignores all state and evidence, meaning it will continue its predefined behavior even when it's damaging to the environment. Pretty similar to a republican's mindset: I don't have to fix it, let the next generation deal with the problems that I caused.

- Wobbles42 1y agoOr to acquire the wisdom to accept it. We certainly are far too young to have a perspective to say which course of action is better -- or indeed to define what "better" means.
