> Roger Penrose used ingenious mathematical methods in his proof that black holes are a direct consequence of Albert Einstein’s general theory of relativity.

Where can I learn more about these ingenious math models in a way that an adult can understand, but one that's been out of math for a while? Is there a good YouTube video?

I'm searching but it's coming up with many hour-long lectures by Roger Penrose that seem unrelated to the specifics of thise prize

You're looking for lectures on the Hawking-Penrose singularity theorems. I don't know if there are any videos about them, but at least knowing the name should help you search.

That might not be possible. I remember struggling with the proofs of the singularity theorems, in the last year of my physics degree, after two semesters of differential geometry. Some of the things that people win the Nobel Prize for are genuinely hard.

The Large Scale Structure of Space-Time is the classic. However, it's the book that Hawking was referring to in his joke about every equation halving the sales.
