I once saw a susskind lecture about the firewall problem where he explained that to check if someone falling into a black hole was incinerated, you'd have to fire so much energy at them, you'd end up incinerating them. Physics is weird. And, apparently, kinda passive aggressive.

BONUS EDIT: here's a Greg Egan short story about transhumans diving into a black hole and trying to do physics on the way down: http://gregegan.customer.netspace.net.au/PLANCK/Complete/Pla...

also here's his page explaining the physics in the story: http://gregegan.customer.netspace.net.au/PLANCK/Planck.html#...
