The End of the Universe Explained by Katie Mack | Cosmology 101 Episode 9

The universe is not just expanding—it’s accelerating toward a dramatic conclusion. This episode delves into the cosmic forces at play, from the mysterious dark energy driving the universe's relentless expansion to the chilling scenarios that might mark the ultimate end.

Will the cosmos fade into darkness, freeze in a cold void, or face a more violent demise?

Join Katie Mack, Perimeter Institute’s Hawking Chair in Cosmology and Science Communication, as she explores the science behind the universe's final fate in this episode of Cosmology 101.

I'm really liking this series.

So accessible, and interesting, with great production, and a very engaging host.

Thank you !! 🚀🚀

This is a great summary in a short video. I've seen a lot of great multiple hour long presentations that give all of the details of the options, evidence, and unknowns, but I don't think I've ever seen one as concise a summary.

Love all these, , , ❤
so weird it started expanding faster !!!
Who'd ever have thought that could happen.
Even an explosion starts off slowly, ,fractionally building up in speed before slowing down,
Maybe our measurements of it previously slowing down were wrong & it's allways been speeding up, , we just haven't reached its maximum potential yet, , , !!
Then it's either the freeze or the crunch. 😅

👍👍I'm about to finish your book (The End of Everything) for the 2nd time. I should probably just break down and buy it instead of continually checking it out from the library. My favorite is Vacuum Decay 😀. I'll pass on the Big Rip😱.

Maybe the universe did not have a beginning and maybe it won't have an end. Everything could be made out of Lambda!

Wrong…
The Big universe does Not have a beginning or End…
The big universe is eternal..

Again, another video ruined because there's music playing in the background

Just looking at the title, I can confidentially say that this is metaphysics, not physics. We are not even certain about how the universe began, and how it works. Just a waste of time.
