- There are only a few distinct properties that can be associated with a
- black hole. They are mass, angular momentum, electric charge and if
- you believe in monopoles, magnetic charge. (ignoring other exotic
- potential charges)
-
- Now, assuming that both black holes were made of neutral
- [anti-]matter, and identical angular momenta, there would be no
- observable differences between the two. All information is lost behind
- the event horizon, whee!
-
- Looks like gravity conserves even fewer quantum numbers than the weak
- force.....
