Happened to watch this by chance, as I already listened to this lecture. Which is great, as Sean's usually are.
But praises for University of Michigan for one of the best Q&A sections ever: it added a lot!

[fieryweasel]

This is a great lecture. I've watched him give it in several different places and it's always a good talk.

sean is smart. we are glad he is here. 5:15

this is like discovering Gold ! Professor Carroll thankyou.

[Jgill]

love sean carroll the way he explains everything makes science even more fascinating 🤯

You are very clever with your mind and so much touched with the practice. You can see of all duality in the glob - is incredible ENERGY and will be so much innovation in the future. Will be no sickness and pain anymore and just so much joy and excitement- everything will be vacuumed up with the black hole naturally. We can’t control the universe, universe is controlling us. And is so important to understand how important you’re for the future of the universe.

Superb exposition, again, by Prof. Carroll, thanks for sharing.

[Iamthepossum]

Many thanks to you for taking the time to upload this to share with us. 🙏🏻 This dude is so fab, I truly adore all of his talks ❤️ Although he gives the same presentations again and again for his public audiences, his content is never tiring as he always imbues it with new color and dimensionality each time. SC is a truly great professor & seems to be a fabulous, caring human being with so much sincerity and concern for educating the common man.

[motivizer]

Thank you so much for making this knowledge available to the general public ❤️

[HarryNicNicholas]

great stuff dumbed down just the right amount for a guy who does finger painting.

[Dreadtower]

Many thanks for an excellent lecture.
I don’t know whether anyone felt as I do but, for me, this really picked up at my level and took me on very nicely.

He keeps on getting better and better as he ages.

At the singularity there’s infinite density which has enough gravity to account for gravitational lensing when combined with the known amount of matter and mass of the galaxy. There’s no need for invisible matter. It’s all there in and around the singularity. What’s not being taken into consideration is the variable of the measures of time and distance the farther away from a singularity it is. It is actually changing the speed of light from place to place. The speed of light is faster in the outer edges than it is near the center causing the lens effect just like a glass lens that slows down light near the center and allows for light to travel faster in the outer edges.

Astroboy was from the late 60's, great conversation, thank you for sharing, peace

58:27 Small historical mistake: Schwarzschild presented a particular solution to Einstein's field equations not a couple of YEARS later, but roughly 1 MONTH later...

If the rate of subjective time reaches zero at an event horizon, does that mean you would see the entire future of the universe elapse behind you if you fell in?

[CarlosElio]

Sean, today is Nov 11. I am in Ann Arbor and wanted to let you know that the results show Nittany Lions lost. You were right. The debate was settled in a few weeks.
I read your books with admiration and interests. Many questins come to mind.

[tonibat]

Glad to hear that he would 'still' hire Einstein if he was here around...
Tks great lecture

This is footage from 1, 000 AD right because there is no other way the mic can be this bad

Consider the notion that the universe might not permit true infinite parallels. Within the intricate fabric of space-time, the idea arises that even parallel paths could converge or diverge due to the inherent complexity and limitations, challenging the notion of endless parallels in our understanding of the cosmos. Exploring such limitations could open up new avenues for comprehending the fundamental nature of the universe.
