6:50 The fun part of a black hole evaporation is that, when it does happen, black hole thermodynamics predicts that the radiation will be entirely in the gamma range and with a luminosity on the order of a supernova scale. This comes from the inverse relationship between black hole temperature and mass - so a smaller black hole radiates faster, leading to a runaway. Conversely, this means that supermassive BHs won't evaporate for a VERY long time.

Thanks for the interesting content! Its been good to watch your channel and get an insight on the nuclear physics of reactors

6:50 small black holes evaporates very fast. It can be like a bomb.

9:24: No, the Hubble Constant doesn't have to increase exponentially. It just has to increase to the point where particles lose the ability to interact with each other for the Big Rip.
The Hubble Constant is the rate at which space exponentially grows. If we call the Hubble Constant H, a constant H means that large distances increase exponentially. Space will keep expanding as long as H>0.

at 11:19 you start discussing how for tiny black holes, Hawking Radiation will make them die that fast, but in this case, it was Dark Energy ripping those tiny black holes to shreds still, although it is true that smaller black holes would evaporate faster

"Awwww, but it's such a _cute_ universe!"

Listen, *100%* of all known spiders live in the universe, therefore the universe is an unforgivable criminal. You gotta let nature take it's course.

After watching your videos and a few other people I wanna thank you for inspiring me to put my appreciation in for college, my whole life I felt as if it just wasn't necessary because there was never something I felt passionate about but you have shown me something that's changed my perspective on a lot of stuff, I applied for a bachelor's in science and engineering so I can try to become a nuclear engineer and I would never have wanted to do this if it weren't for you, thank you.

I've been binging your channel like a series on Netflix. Love the content bro.

15:25 Tbf, a false vacuum wouldn't destroy the universe. It expands at the speed of light, so the expansion of space keeps a false vacuum contained in its own observable universe.

considerin the second scenario, wouldnt this dark energy start ripping apart Quarks?

As far as I understand Quarks they create new (opposite) quarks when enough energy is put into them, so wouldnt at some point in the second scenario the entire universe fill with more and more quarks until gravity is stronger than the dark energy ?

[Rusty-METAL-J]

Thank you Tyler for doing the video of the guy breathing the Noble Gasses. I have heared the the rate of expansion of the universe is still increasing. That being said this video claiming that it is slowing confuses Mee.

[markbarrett]

Thank you for all your videos, I never miss one!

Wow just came across this channel, thank you for the free knowledge. Subscribed! much love from the NL ❤

hey remember animation vs maths you watched a while ago? Animation vs maths came out!

When Kurzgesagt releases a video, I first see the video, then the soundtrack on Epic Mountain, then you reacting to the original video.

[danielthemangrande]

Hologram theory is the single craziest theory and kurgegast video

[AkashRockz]

Excited to see your review on animation vs physics.

It seems likely that the first scenario will happen, where dark matter stays the same and the universe slowly drifts apart more and more. But I think it would cool if the universe did a reverse Big Bang and then started fresh with another Big Bang, with every bit of matter in the universe recombining into one and then separating out again into a brand new universe.

[RandomEG]

think of this, the big crunch and bang, is actually a bounce. imagine a universe getting infinitely small, and then big, and then small, and then big, etc. that explains the big bang, and how matter was NOT created. it cant be created or destroyed, so that would explain everything.
