1. The event horizen is the middle of the hole. once ur there, you're stuck. the accelleration to get away from one has to be faster than the speed of light.
2. The escape velocity has to do with the size of the object and its mass, if the object is small and has a lot of mass, you will need nore velocity to escape it. that also describes a black hole. the speed of light is not enough to escape it.
3. The escape velocity must be very high if the size of the black hole is small with a very high mass. light gets bent if it passes to close to a black hole.
4. Stellar black holes are created by dying stars super massive black holes are in the middle of a galaxy.
5. They thought black holes were invisible stars.
6. Uses the stis to use infrared visible and near ultrviolet light.
7. The volume of a black hole is huge-false
black holes will eventually destroy the universe-false
