All right, you've got us... there's not much fun to be had at this page (unless you're Jason Burt). THAT'S BECAUSE HAWKING RADIATION IS NO LAUGHING MATTER! Ahem, I mean, uh... Okay, just in case you missed it the first time, here is a 3-D animation Kevin made with Maple showing the collapse of a black hole (I'm putting this in two places because it was a pain to make and I want to make sure it is properly appreciated). This demonstrates the "rubber sheet" analogy of general relativity, and one can see how a massive object curves the space-time around itself. In the case of a black hole, it "punches through" the space-time.
All right, by popular demand, it's time to Build Your Own Black Hole! Well, not exactly... but I'll build one for you! This is a good example of a java applet gone bad. Kevin attempted to make this an interactive program, but only managed to prove that:
(1) He's a crappy programmer.
(2) Even applets that don't do anything are annoying.
(3) Java is a large pain in the @#$!.
Anyway, the purpose of the applet was to allow the user to enter in a mass in grams and the program would spit out all kinds of black hole information for you. As it stands, the interactive part never materialized. So, here's some spoon feeding for you:
One gram black hole
One "John Fuhrman" black hole
10^15 gram black hole (primordial)
Moon size black hole
Earth size black hole
Solar mass black hole
Three solar mass black hole
