I love this! I've read The Story of the Cosmos, and you really did your best to put the cookies on the bottom shelf, but still above my pay grade lol. Highly recommend the book. I can't wrap my brain around an exploding star leaving a gravitational hole. This article helps me visualize it even better. It's just incredible. Do we know where the gravity comes from? (Maybe everyone does and I haven't been paying attention.)

Thanks for the kind words about the book, Mike.

According to Einstein's General Relativity, gravity isn't a true force the way, say, electromagnetism is. It's more like the result of the way objects with mass or energy warp spacetime around them. I definitely recommend Thorne's book if you want to know more.

Ha, no, I didn't think it was commentary. You're too smart for that. I'm not.

I've never been there, so it's not commentary, lol. It just seems like the most iconic big American city.
