Civilizations at the End of Time: The Big Rip

Current science and cosmology tell us the Universe will slowly die and ebb away countless trillions of trillions of years from now, but another model - the Big Rip - says that end may come far sooner, ripped apart by dark energy. Could civilizations survive the Universe itself being torn apart at the atomic scale?

What a joy it is to return to this series. This was the series that got me hooked on your videos, and your signature style keeps me coming back for more. Stay awesome Isaac.

I for one love the idea of seeing you learn to fly. I've always been an aviation nerd, so it'd be fun to watch. Also "A Brief Moment of Eternity" sounds like one hell of a science fiction book title. I'd use it, but I'm not a good enough writer to do it justice.

What's even stranger, is that even though an infinite three dimensional space is, intuitively, much larger than an infinite one dimensional line, Cantor showed that, nonetheless, they both have the same cardinality. In fact, an infinite three dimensional space even has the same cardinality as a finite line. To quote Robert Kaplan, "there are just as many points in the infinite universe as on the horizontal bar of this T."

Infinity is weird.

Math Note/Correction: As of the moment I've got 4 different contradictory explanations of why some of my comments on adding infinity this or that way, or how many numbers are in between 1-2 compared to total integers, is wrong or badly phrased. Everyone seems content with the overall explanation where it's relevant to the video, thankfully - An infinite Universe can still expand and infinity isn't a number - but needless to say, take that infinity math with a grain of salt :)

For everyone offering corrections on it though, please try to keep the explanations where someone who isn't a mathematician might have a chance to understand them or otherwise link to some page where someone does give such an explanation. And while you are welcome to call me an idiot, please do not call other commenters on the thread idiots just for saying your answer didn't make sense to them.
Edit: Also, yes, I am kicking myself for not thinking to make a R.I.P. joke on the the Universe dying by the 'Big Rip' :) Can't think of every good pun.

I love how you spend the time to add captions. I use them a lot for making sure I catch everything or know how to spell certain words or names for me to look up later. It’s also great for times when the area around me is noisy, which is often. Thank you!

im never this early for an isaac arthur video and ive even already got a drink and a snack ready!

[philiprobey]

One thing other YouTube celebs could learn from Isaac is that of engaging with their fans. I've left about a dozen comments on his Patreon forum and I am pretty sure he responded to all of them. Part of the reason I upped my support.

I started learning to fly last year, and would be thrilled to see some one else go through it. Too few people take advantage of the fact you can just go to an airport, and learn to fly. It changes your perspective on things in so many ways. You never see the world the same way again.

I love these brain-stimulating videos, Isaac! Being buried in the world of meteorology, I sometimes forget to let some out-of-the-box thinking soak-in. Also, I once again must compliment you on the excellent lead-in your sponsor at the end. Perfectly executed! Thank you, as always.

For some reason, i love to watch these videos while working out. I dont know how many times I've heard you talk about space travel or speculative sociology while pushing my muscles to their limits. Thanks Isaac

[fredkelly]

Having trillions of years with nothing but the end of all things in front of you I'm pretty sure some of that time would be taken up on doing something about it. In fact I would say they will have the power to not only extend the universe's life but to extend it indefinitely.

How does this channel not have 1m subs yet? Been watching weekly since 2017, another great episode!

26:30 "Let's be honest, nobody really thinks of their civilizations in million year terms" And i took it personally x, )

[riley]

I'm so glad this series came back

[JOhnDoe-nlwj]

just when you thought you had enough existential crises to worry about
Isaac: "time might drain out of the hourglass and leave the Universe in a frozen instant"
nice

[MalcolmJones-bossjones]

I love Thursdays !!! Thanks issac, grabbing my popcorn now

[freddyjosereginomontalvo]

As always say : Awesome channel with awesome content and great quality 🌍💯

[Rumble-Tusk]

Thank you for confirming an idea I had in college was reasonable - namely that big rip + quark pairs would generate huge numbers of additional quarks. I brought it up to a professor of mine and he dismissed it saying that they would simply get redshifted into oblivion but that never really made sense to me. How could something get redshifted in its own reference frame?

[Higgzboson]

Great video ..one of the best channel ever

[Robert-ryxe]

I understand almost none of the science or logic and yet I love watching videos like this.
