From calculations of quantum tunneling through the horizon of a metric (black hole, Rindler..) Hawking/Unruh temperature can be calculated!

Using this method it is recently claimed that the so called Black hole information paradox can be solved:

- Zhang et al. (2009): Hidden Messenger Revealed in Hawking Radiation: a Resolution to the Paradox of Black Hole Information Loss The answer is, that the information that seems to be lost when matter falls into a black hole is in fact completely carried away by Hawking radiation. So in the whole process no information is lost.
