Blackholes and light

  1. Dec 16, 2015 #1
    If blackholes were able to stop light from escaping , then would it mean that photons do have a certain mass (no matter how much negligible it is ) and if it does then how can something that has mass (photons) travel at the speed of light. wouldn't the speed limit aplly to them too?

    No, that is not the reason that they cannot escape. Take a look at some of the similar discussions below or ZapperZ's statement in this thread.
