Even though some of these would be well-known to someone with a passing interest in astronomy, the passion Phil Plait writes with makes me love everything he produces. This time, Bad Astronomy on ten things you don’t know about black holes.
- It’s not their mass, it’s their size that makes them so strong
- They’re not infinitely small
- They’re spheres. And they’re definitely not funnel shaped
- Black holes spin
- Near a black hole, things get weird
- Approaching a black hole can kill you in fun ways. And by fun, I mean gruesome, horrifying, and really really ookie
- Black holes aren’t always dark
- Black holes aren’t always dangerous
- Black holes can get big
- Black holes can be low density
