| • | If you do make material fall into a
black |
||||||||||
| hole, material will be falling at close to |
|||||||||||
| the speed of light when it reaches RS |
|||||||||||
| – | If that falling gas collides with and heats |
||||||||||
| other gas before it reaches RS, then
light |
|||||||||||
| from that hot material (outside RS) can |
|||||||||||
| escape (important in quasars!). |
