As far as I understand it, things will appear, to an external frame of reference, to "freeze" as they hit the event horizon, BUT that's only because of the speed of light - from THEIR frame of reference, they fall in just fine.

It might be reasonable to say that from an external frame of reference, it's always the same time in a blackhole, but not from an internal (unsafe) frame of reference. But I'm not a blackhole theorist.

Incidentally, it is theoretically possible to fall through an event horizon unharmed, but you can never escape and good luck with the singularity

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.

Hera, can you please state what training you have received which allows you to comment on whether "recent developments" in a field so badly understood as quantum field theory in strongly curved space are interesting?

Thanks in advance.

While we're asking clueless physics questions, how does gravity fit into the whole no-work-without-energy bit? I mean, if you need to expend energy to move objects...does the universal effect of gravitation have some sort of "power source," or is it exempt from the usual rules somehow, or is it one of those things we don't know yet? Yeah, I feel really dense asking this, especially since I don't know any of the proper terminology.

a) In the non-relativistic sense you can view the gravitational field as a means to store energy. Two pointlike massive objects m1 and m2 seprated by r have potential energy due to gravitation -Gm1m2/r (using infinty as the zero point). Changes in their configuration lead to transfer from the potential energy in the gravitational field to kinetic energy (or some other form)

b) In general relativity in a global sense energy is not conserved. You can define some local quantities which conserve "energy" but in general these are not as useful as global energy conservation is classically

Let's get this over.

You probably know more about the subject than I do.

What point are you at in your education? I'm guessing that you're an undergraduate, but correct me if I'm wrong.

But If you are speaking generaly I can only say: "No **** Sherlock."

BTW, there is at least one other real physicist still around (Jon Miller; he does nuke stuff). There used to be another dude in HE theory (Rogan Josh) but I haven't seen him in ages. Jon Miller? Well, I suspected he was, I would have never guessed you had your level of experties. I suppose my opinion of you has improved, you are still an arongant ass but at least you have good reason to be one.

[Kotyara]

Are you going to continue past a baccalaureate? How much longer do you have before you need to make that decision? If you are going on, what are you thinking about in terms of grad school (both area of research and school)?

and you run off on your companions whilst barhopping. i don't know how i made it back to the hotel, let alone how you managed to do it.

Theoretical physics is clearly a club for the socialy inept.

They make up their little equations and then pretend to solve them/dispute them or whatver else they do.

It's purely to hide the fact they can't meet girls.
