Most of you know how much I love all things space. Combine that with the brilliant cartoon artwork of Jorge Cham, several astrophysicists talking about their work, and my day is made!
When it comes to astrophysics and phenomenon like black holes, most of us think we have the topic covered. After all, the television and film industry has devoted a huge amount of reel space to presenting dangerous scenarios concerning black holes and their ilk.
It turns out there is a lot of straight forward science that is not well understood like black holes don't actually suck material in. (The word "hole" probably threw the scriptwriters off.)
Anyway, check out the video or read the explanation at PhD Comics. Both make it easy to explain to friends at a bar, baseball game, or during speed dating. Go science!
