so the hole is plugged by matter and it evaporates because nothing can get in yo fuel it.
[ so the hole is plugged by matter and it evaporates because nothing can get in yo fuel it. ]
It evaporates due to this: http://en.wikipedia.org/wiki/Hawking_radiation
The smaller the hole, the faster it evaporates, unless you add matter at a faster rate than it evaporates.
Basically in empty space there are particles and anti-particles that pop in and out of existence that then combine and annihilate one another.
If they pop into existence close to a black hole one particle gets eaten by the black hole and the other can escape causing the net loss of energy ie. mass to the black hole.
