Nothing does escape a black hole. The Hawking radiation, if I remember correctly, comes from one pair of a virtual particle pair that appears right on the edge of the black hole. One of the couplet spontaneously appears on the inside, the other on the outside.

I think you may be confusing them with neutron stars or something similar, which are indeed insanely massive for their tiny size but are a different animal from black holes.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'

Brief history o time: Quote: Primordial black holes with initial masses less than this figure would already have completely evaporated, but those with slightly greater masses would still be emitting radiation in the form of X rays and gamma rays. These X rays and gamma rays are like waves of light, but with a much shorter wavelength. Such holes hardly deserve the epithet black: they really are white hot and are emitting energy at a rate of about ten thousand megawatts. The smaller they get, the more they emit, and the more energetic their emissions.

Ah, my mistake. I thought you were saying they were optically visible. I need to re-read some Hawking.

Would it be helpful to suggest you look into adopting new parents?
