Welcome to Starshrunks!

Hi, can I get a full black with quantum foam infusion? Served HOT!

Name?

Hawking.

Thanks! Your name will be called in [UNDEFINED] minutes and served with free spaghetti. Plan to stay at the pickup counter until the heat death of the universe. Enjoy your [neverending] day!

A white dwarf, a neutron star or even a strange quark star are all still made of fermions. The Pauli degeneracy pressure helps hold up the stellar remnant against gravitational collapse, preventing a black hole from forming.

That's my Goodfellas soundtrack cover band.

It's sort of like a big, weird library where you can spy on your daughter from like 50 years ago and then send her a message on a watch.  Don't get mad at me I don't make the rules.

I hereby demand that I be given a Fark account: Just one singularity, mind you!


What about second singularity? Elevenses?

HairBolus: > There must be a singularity at each black hole's center

Isn't this a stupid statement?

the whole black hole is a singularity, not just the point at its center. In fact there all the points in a BH are the same so there are no distinct points within one, particularly not a center.one. A BH is is just an abstract point with measurable  volume.


Not true.  The interior of a black hole, meaning the space inside the event horizon, is just an ordinary vacuum (modulo random stuff transiently falling through it).  In a sufficiently large black hole you could in principle survive the tidal forces and move around within the black hole, briefly, until you hit the central singularity.
