•Remember – gravity is same as
before, away from mass
–Black holes do NOT necessarily pull all
nearby material in
–A planet orbiting a new black hole would
just keep on orbiting
as before (assuming the ejected
material or radiated energy didn’t have an
effect)
–
•Any mass can potentially be made into a
black hole – if you can compress it to a size smaller than RS = 2GM/c2
