At the center of a black hole is it the same time as the moment of its formation?

If I was heading toward the center of a black hole, I wouldn't be that concerned about what time it is.

Stars are purty.

Black stars are n vis ball.

/me runs from the high powered physics lecture!

(actually I am just marking this thread so I can follow it, but I had absolutely nothing of substance to add. Glad your back KH!!!)

If you're talking about Spacetime&Geometry then yeah, that's a fine start (as long as you covered to the end) but it's still pretty elementary.

Glad it meets your approval.

I know all I have is a history degree, but i've been an amateur astronomer for a long time now.

a) It's not because of "the speed of light"; it's a general relativistic effect.

b) They haven't had time to fall through yet. In fact, from any sane perspective it's hard to explain how a black hole can form in finite external time. AFAIK it's possible that there are no black holes. Only objects which are almost black holes.

When the mass of the back hole increases won't the increase in the Schwarzschild radius mean that even to an outside observer objects can appear to have ended up inside the expanded Scwarzschild radius?

Hey guys if you're not too busy insulting one another and being really smart, I got a question for ya...

Good Question! Now why didn't you just ask that in the beginning?

To a hypothetical observer who was at the center at it's formation?

[Lancer]

I was watching a sci channel show about time. The guy, I don't recall his name, that did the show stated that 'time stops in the center of a black hole', or something like that. Well, that means that time would be stopped at the time of its formation, hence the question. Whether its from inside or outside, well the guy doing the show was outside so I'll go with that.

Yeah, but th e latter is actually a 3rd order effect when you work it out.s

There is literally no inforamteion as to the passageof time at the center of a vlack hole. Even if toyu assue that our physics model is accurate then the uestion is meaningless (it is impossible to travle between the center of a black hole and the event horizon just as it is imposible to travel betwiin any otuside point and the evens horizon.

In other words, the question is ill posed. I cannot provide a sane answer.

My head is spinnig.

[Lancer]

Technicly, all of our heads are spinnig, yes?

[MattBowron]

hey KrazyHorse, I was just wondering, do you think the universe at the moment of t=0 was similar to a singularity of a black hole in any way?
