Hawkins radiation and theory

*** Quote ***

Cosmologist, astrophysicist, and physicist Stephen Hawking showed, in 1974, that black holes should emit electromagnetic radiation with a black body spectrum; this process is also called black hole evaporation. In brief, this theoretical process works like this: particle-antiparticle pairs are constantly being produced and rapidly disappear (through annihilation); these pairs are virtual pairs, and their existence (if something virtual can be said to exist!) is a certain consequence of the Uncertainty Principle. Normally, we don’t ever see either the particle or antiparticle of these pairs, and only know of their existence through effects like the Casimir effect. However, if one such virtual pair pops into existence near the event horizon of a black hole, one may cros
s it while the other escapes; and the black hole thus loses mass. A long way away from the event horizon, this looks just like black body radiation.

It turns out that the smaller the mass a black hole has, the faster it will lose mass due to Hawking radiation; right at the end, the black hole disappears in an intense burst of gamma radiation (because the black hole’s temperature rises as it gets smaller). We won’t see any of the black holes in the Milky Way explode any time soon though … not only are they likely still gaining mass (from the cosmic microwave background, at least), but a one sol black hole would take over 10^67 years to evaporate (the universe is only 13 billion years old)!

There are many puzzles concerning black holes and Hawking radiation; for example, black hole evaporation via Hawking radiation seems to mean information is lost forever. The root cause of these puzzles is that quantum mechanics and General Relativity – the two most successful theories in physics, period – are incompatible, and we have no experiments or observations to help us work out how to resolve this incompatibility.

we are of course assuming all matter falling into the back hole is the opposite of what the black hole is composed of ... 
but on average both positive and negative particles will have fallen in and thusly the energy 
balance should be Zero unless the black-hole carries a polarised charge :-)
so let us summarise infinite equal distributions of positive and negative = 0 if annulled,
it is also possible the created mater replaces information with information and thus new information replaces old.

such information replacement would be in line with thermodynamics : the increase of uniformity within a system (cerca 1979) and random rather than ordered data...

such a process can be found in VHS Tapes.
and that's if the matter inside the black hole carries a charge since it might not..
