I just want your guys opinion on my idea against E=mc

  1. Mar 5, 2015 #1
    so i had this idea for a while now,
    if you would take a black hole, and put a laser next to the event horizon, facing away from the black hole, the gravity from the black hole would pull the photons in right? I was thinking that the force that it takes must be bigger than the power from the photons which are trying to get away, right? My question is if the photons would remain still, or get pulled into the black hole, which is against Einsteins E=mc2, cause the photons would exceed the speed of light right?

    p.s. Pleaso no hate on my bad english, i am just 14 and from the Dutch, so yeah

    Hi siebe22, welcome to PF. Your English is great, you don't need to worry about that at all. However, your understanding of black holes is all wrong.

    I would strongly recommend that you start with standard Newtonian physics before jumping into general relativity. This is a great place to help learn, but we can't miraculously help you skip all of the basics and jump right into advanced physics.
