Bad Astronomer - Why do black holes have so much gravity?

His explanation could be a bit better. The key to the answer to the viewer's question is that the universe doesn't recognize macro objects like stars, planets, etc; as far as gravity is concerned it's all just particles. He comes close to this when he talks about getting closer to the black hole because it's smaller, but he should have taken it a step further. If you were standing on the surface of a star, only some of the particles that make up that star would be close to you, most of them hundreds of thousands to millions of miles away from you. Since gravity's strength is dependent on distance, those far away particles would have relatively little effect on you. If you were standing on the surface of a black hole, those particles would all be only a couple miles at most away from you. That's ignoring the issue of what a black hole is really made of, which isn't relavent here; to be more accurate we could just replace of the concept of "x number of particles" with "x amount of mass".

That said, Phil Plait is good stuff. I check his blog daily.

Diablo III - gameplay video (witch doctor, barbarian)

Here's the link to download the source video instead of playing it in the browser. The video is 195 megs, and the browser tries to load the whole thing into memory. I use VLC to play flv files, I'm not sure what else works. And as a bonus, the second link is to the cinematic trailer.
