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
