Generally speaking. Specifically, it was shared by the astronomers who revealed to us the Milky Way’s central black hole and by Roger Penrose, who proved that in general relativity, every black hole contains a place of infinite gravity - a singularity. But the true impact of Penrose’s singularity theorem would is much deeper - it leads us to the limits Einstein’s great theory and to the origin of the universe.

I'm an electrician from england, and have no formal education above my electrical qualifications. I have always had a love of physics and space, and channels like yours are an absolute blessing for people like me. I may struggle to keep up with some of the concepts discussed and end up rewatching and furthering educating myself on the subjects, but without this channel I would never be able to learn about the fabric of our reality to the extent that you have made possible. Thank you so much for your hard work.

When this universe ends, Matt is gonna come out, make a speech that ends with the words, "on the next episode of Space Time". He'll then explode, creating the new universe.

So freaking happy that Penrose got the Nobel Prize, he's had it coming for a long time. He's a mathematical powerhouse, and even if it's likely not an accurate picture of reality, Conformal Cyclic Cosmology is one of the most creative interpretations of taking the connection between space and time to its absolute limit. Huge fan of the guy

"the nobel price in physics this year went to black holes,..... but since we heard no response back, we're giving it to someone else"

Absolutely wild how easily he makes these concepts. I'm learning the earlier workings of differential topology and you've essentially made some of the hardest mathematical concepts so easy to understand. Thank you!

"The Nobel prize in physics this year went to black holes" Of course, nothing can escape a black hole, not even a Nobel prize

In the history of Nobel prizes there are few people more worthy of it than Sir Penrose. A remarkably insightful human.

I know these videos take a long time to make but I'd love to see one on Boson Stars! I became aware recently of the possible existence of these exotic stars but my understanding of bosons is very weak so it's difficult to wrap my head around. Thanks for all you do, Matt and the rest of the team!

I met Penrose after a lecture he gave in Edinburgh. He came to the ceilidh after the event. He didn't dance but you could tell he wanted too. Legend

It’s very satisfying that you’ve been spending more time on Penrose. Super cool.
