And remember: The universe will end, but not for a while… probably
I don’t want to alarm you, but the world is going to end. All of this. Gone. And scientists are certain all of this will happen. On the bright side this isn’t going to happen for 4-5 billion years. It makes me wonder: In a universe bigger than we can fathom, across eons of time, could… all of it end? Everything? The whole universe? Yes. And it probably will. Here’s how.
Note: The copy of "The End of Everything (Astrophysically Speaking)" discussed in this episode was provided free of charge by the publisher. As in "the physical copy you see on screen." I also bought the book myself because I love astrophysics! But that version is on my Kindle :)

Just in case the universe does end soon, shouldn't you make sure you're subscribed to my channel before it happens? Click the bell, too, so I can warn you when the end of everything begins. And find me on Twitter and Instagram: @DrJoeHanson/@okaytobesmart

The Universe: expand The big crunch: exists The universe: "just when I thought I was out, they pull me back in"

The Big Crunch is the most fun, Heat Death is the most depressing, The Big Rip is the most terrifying, and Vacuum Decay is the most worrying.

"I never had more fun learning about how everything will cease to be" Joe, u okay? COVID finally getting to you?
-
Vacuum decay wouldn't destroy the entire universe, since it only travels at the speed of light, and dark energy is pushing space between galaxies faster than the speed of light. So if a segment of the universe starts vacuum decay then it would only affect the local area of the universe around that point, and shouldn't permeate throughout the entire universe. IMO

YouTube: Is this a good recommendation for you? Me:yes YouTube: why? Me: useful

i misread the notification as: ''4 Ways to eat the universe"

0:29 Red was not The Imposter.

Recommended reading: "Schild's Ladder" by Greg Egan, which is set in a universe where vacuum decay is actually happening (but expanding at only half of light speed). When they figure out how to "cross" the boundary (... it's complicated) they find that there are new life forms and new civilisations developing within the "bubble."

We just gonna pretend the red guy from among us wasn’t floating in space??

4 ways to end the universe Ans. Delete button. Ans. Collect infifnity stones. Ans. Write 'universe' in death note. Ans. Anger Lord shiva to do Tandava .

I like how Joe says "it could be worse though" with an excited smile XD😂
-
I know the Big Crunch isn’t likely but it’s my favorite- it just feels so poetic and nicely symmetrical (and makes the cyclical universe theory easier to imagine)
-
Imagine if someone from the 100s billion years watching this, they be like wtf it’s happening in my life time Lmao 😂

This video: exists Me to 2020: (softly) don't...
