Time at the center of a black hole?

  1. Jul 21, 2013 #1
    Sorry if I am woefully uninformed, but I am really curious.

    What happens to time at the center of a black hole according to general relativity?

    Basically, time stops at the singularity.

    I would put it somewhat differently than DaleSpam did. The singularity is not a place in space; it is an instant of time. This instant of time is in the future for any object inside the black hole's horizon; and the singularity is a boundary of spacetime, so there is nothing to the future of it. So time stops for anything that hits the singularity, because it hits a future boundary of spacetime.
