But black holes evaporate?

• zamalek 11y ago
  The curvature is the cause of the event horizon, the mass or energy is the cause of the curvature. Remove energy and you remove curvature, remove the curvature and you remove the event horizon.

  Only if you go beyond general relativity. Once you include quantum physics there are some strong indications that black holes must somehow evaporate (although this hasn't been observed directly), but that model is still incomplete.

  Yup, and that's a problem that hasn't been fully worked out yet.
