Hmm... I don't have a strong enough grasp of number theory, apparently.

Which is why a small black hole would be short lived. But, then, it does
have an event horizon, and nothing can escape a black hole. So, wouldn't
it remain a black hole after being compacted?

Right, what was I thinking. Only the frequency of the light changes. The
speed doesn't change.

Heck no. Just a basic home finance program. Cost about US$50.
