wow! I'm SO glad that he is filming lectures for teh intarnets.

The analogy of a thimbleful of neutron star as weighing as much as 50 million elephants is pretty good, but honestly, it is very hard to imagine 50 million elephants. I have heard the analogy before as a thimbleful of neutron star weighing as much as the Rockie Mountains. That is more viscerally signifigant to me.

I have to say, I totally <3 his take on the infinite density of a singularity. "When I say that a singularity is infinitely dense, really I am just professing my own ignorance."
This video is a huge boon for Science. Bravo! Thank you for posting it mauz!
