Isaac Newton’s Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton’s equations. They don’t always accurately represent reality. Einstein’s General Theory of Relativity is a more complete theory of gravity. So does using the General Theory of Relativity eliminate the singularity? No. Not only does it concur with Newton’s Universal Law of Gravitation but it also reveals a second singularity, not at the center of the black hole but at the event horizon.

(prepares to watch another episode where he doesn't understand 90% of it but loves it anyways)

FINALLY A PHYSICIST AND A MATHEMATICIAN GOING ALONG WELL!

[PhaTsp]

5:18 "It's actually quite easy to see where the singularities are"

Mhm quite indeed it is.

"You are so dense that your personal space should be called event horizon"

[pepedecoatza]

For mathematicians, infinity it is just a number, for physicist, it means madness.

[marksteven]

May this channel live on forever, or at least until the sun's radius starts growing
This is some solid content

[martinsalko]

blackhole: imma gonna crush you
planet: I use non-euclidian reference
blackhole: F****
*blackhole dissolves*

"Today we're gonna keep it simple." 🤔😅

I never thought I could be taught to appreciate pain, but the way my brain hurts when I watch PBS space time just did that. This was certainly the case with this episode. I want to go full brain-masochist now.

This switching of the role of space and time inside the black hole is kind of what Interstellar was hinting at near the finale when Cooper began experiencing a connection to time rather than space. Although the idea he could interact with his past I'm not sure about, I believe this switching of the roles was what the film was hinting at. Great episode!

"We are gonna keep it simple" ..ITS A TRAP!

[justdev]

THANK you Henry. Your generosity makes life a bit more interesting for broke people like myself that couldn't give like you did. I'm grateful too, not just the host of this great show.

[Daniel-dcmr]

Wow, you've made some gains. Good job

[joesam]

Matt: "That makes sense"

Me: "??? how ???"

[jezfrench]

I dont know why I'm watching this. I struggle to subtract a darts score.

[MrDeritamichael]

These videos are way above what I currently understand, however I love them and can't get enough. Please keep up what you guys are doing, it's beautiful and interesting.

[Stvz]

I don't even know why I'm subscribed. I barely understand a word he says.

[genevieveschulz]

3:02 "Alright, that makes sense." TO WHOM?

[sugarymushroom]

These videos by PBS Space Time are some of the very coolest vidferos I've seen on YouTube.

It's almost as if spacetime is quantized rather than continuous, and the idea of "0 distance" between two separate objects is inherently invalid. That would suggest spacetime is similar to every single other aspect of reality ever encountered. How crazy would that be? Obviously it's got to be continuous and not quantized, like nothing else in the universe is.
