Black Holes

Calculating how smal something must be to collapse into a black hole.

Discuss

A star has to be *large* enough to collapse into a black hole, other wise it explodes and then turns into a neutron star, a high density star that has enormous gravity, but nowhere near the amount of a black hole. A star has to be massive to become a black hole, perhaps a large blue or large red star, because in order for a black hole to form, massive amounts of matter have to be "compressed" into a small area.

As for entering a black hole, anything can enter it, it's getting out that's the hard part. After entering the black hole it's theorized that matter is stretched to an infinitely small "strand" of matter. Gettting out of the black hole is feat reserved for the matter that makes up the black hole itself.

Ah, thanks.

Ahem, I believe the OP was referring to accelerated particles.

Ask CERN

Ah ok thanks for that

I'd say, they gotta be pretty fucking big. Is that enough for you?

Is this an advance wars thread?

We don't know yet.

But have a look @ http://en.wikipedia.org/wiki/Quantum_black_hole for some interesting information

We can't actually find the size of a black hole. All of our ways of measurement require some sort of reaction to our action, and since black holes absorb everying but hawking's radiation, we cannot see its size.
Because we cannot find the answer, we cannot establish an axiom for the calculation of its size.

Orange Star will crush black hole

WOW a black hole!

I do not believe anyone was wondering about how big a black hole is, rather what the smallest amount of energied up matter (or particular/sub-particular) is that can turn into one is.

However, I believe it is possible to get an idea of it's size (or rather, the area of a definite bottomless space/time continuum pit) by using light, the big issue is finding a hole and getting a light source either behind it or in the right place, but there may be other things on the electromagnetic spectrum that would make measuring it easier than using photons.
