Black Holes It has been proven that black holes are not so invincible; they can
emit radiation, and therefore loose mass (due to E=MC²). Calculations
have confirmed that black hole ought to emit particles and radiation
as if it were a hot body with a temperature that depends only on the
black hole’s mass, they are inversely proportional: the larger the
mass of a black hole the lower it’s temperature.
The answer is that the particles do not come from within the black
hole, but from the “empty” space just outside the black hole’s event
horizon.
This understood in the following way: what is thought as “empty” space
cannot be completely empty, because this would mean that all the
fields, such as the gravitational and electromagnetic fields would
have to be exactly zero. However, due to the uncertainty principle
(which states that the more accurately you measure the position of a
particle in space, the less accurately you could measure its velocity)
the field in “empty” space cannot be fixed at exactly zero, because it
would then have a precise velocity (zero). Therefore there must be a
certain minimum amount of uncertainty in the value of the field.
Due to scientific theory every matter particle has an opposite match;
or if you like an antiparticle. If these particles are seen as matter
particles, then one of the partners of the particle/antiparticle pair
will have positive energy, and the other negative energy. The one with
negative energy will be condemned to be a short-lived virtual particle
