How the Universe Will End

Neil deGrasse Tyson describes the different prevailing theories on how the universe will end.

What does dark energy accelerating expansion lead to? Can you rip a quark apart? Learn bout the heat death of the universe, the big rip, and whether the universe could recollapse on itself to create another big bang. Could there be infinite big bangs?

How do you think the universe will end?

[light-master]

I came to Startalk for the science, but I stayed for the friendship between Neil and Chuck.

[Hazar]

Thank you so much for going back to the studio. Much better audio quality and no delay between the speakers.

[cindygrce]

Neil is so good at explaining stuff so that I can pick up on what scientists theorize without making me feel dumb.

The universe may end, but the cameraman still won't die

[n.pstudioanimations]

😂 I’ve been watching you explain the universe ever since I was very little and you have played and still continue to play a huge role in my love for space and science in general thanks for teaching me most of what I know about space and how it all works

[Rbilicious]

5:27 Chuck, you were there for the Big Numbers explainer!

[dfwdeadshot]

Hi star talk thanks for all the great content.

[laveeshtomar]

I will create a new universe for y'all after 100 likes

[DaveQZ]

I'm glad I'm alive at the same time as Neil and Chuck. They have such a great way of explaining science to the masses.

We need to figure out a way to digitize these two so they can keep going.

[InnerStereo]

If a page will be removed and they won’t know it, then how do we know that this hasn’t already happened infinitely already?

[reneonier]

0:10 Chuck, you owe me a pair of eardrums.

[RealmsSMPStudios]

Fun fact, if we go down the heat death route, there’s a stupendously, ludicrously, unbelievably small chance of a new big bang occurring due to quantum fluctuations in an estimated 10^10^10^56 years…

[MoosesValley]

You guys are so awesome and entertaining. I'm a long time amateur cosmologist, and keep pretty up-to-date with the latest cosmology theories and discoveries, but I still love to tune in to StarTalk to enjoy the banter between you two. A++

[IQmates]

I love the new edits on StarTalk. Illustrations make it much easier to comprehend things Neil explains.

[megamihestia]

Chuck: 10 to the 100th, that’s a thousand.
Neil: I have failed my mission.

[barehope]

😮I love your channel. Thank you for sharing your expertise with us

[willieluncheonette]

could you please give an exact date so i can make sure to watch the complete bucket list of TV shows i want to see before the end comes.

[WishItWas]

The best part of this video is learning about Ground News.

As "news" became more polarizing on each sides' major platforms, I stumbled on StarTalk's video with the creator of the Ad Fontes Media Bias Chart. From then on, I simply only read stories from those center/top agencies, such as AP or Reuters.

Ground News not only utilizes this monitoring platform, but two other major ones I never heard of, and looks to do it in an easy to absorb and navigate interface. I am excited to subscribe, yet ultimately sad that I even have to. Thanks StarTalk!

The universe may not end in my lifetime but it may end in my ghost time and still scares me.
