B Curious question about gravity

  1. Jul 17, 2017 at 1:19 AM #1
    Heyy guys, this just came to my thought, if black holes have enough mass to generate gravity strong enough to bend light and (I m not sure about this but remember reading this somewhere) if gravity travels at the speed of light, does it not make gravity a captive of the black hole??

    It's not that gravity travels at the speed of light, it's that changes in the gravitational (gravitational waves) field travel at the speed of light. The gravitational field that develops gradually as the black hole forms still exists after its formation.

    ...in either case, that doesn't mean gravity is light.
