What do black holes turn into?

Black holes evaporate. Their mass turns into radiation: photons, neutrinos, gravitons. However, the evaporation process for massive black holes is very slow. So, a black hole, with a mass equal to 10 times the masses of the Sun, will evaporate in an unimaginably long time – 10 ^ 69 years.
