Hey y’all! My latest column is up: “What makes black holes so black?” I’m afraid the new io9 frontpage is a bit punitive, and things drop off of it nearly immediately. I think this is one of my better ones (you’ll learn some cool tidbits about how negative energy work), so be sure to tweet, facebook like, stumble, and digg it. If you like it, of course.
And if you’re new here, be sure to check out the “Physics” tag and others to read some cool things about expanding universes and the like.
