Schwarzchild Inside the Event Horizon
Lähetetty: 3.8.2011 13:06
Otsikko: Schwarzchild Inside the Event Horizon Keneltä: mathematician Kopio: ________________________________________ I think that problem would be that in reality GR (General Relativity) is not full 4-dimensional. GR is really (3+1)-dimensional and time dimension is different kind that three space dimensions as mentioned reference below. Arbitrary 4-dim coordinate transformations are not allowed in GR.. For example in reference below it is mentioned that it is not allowed to transform "meter stick" to "clock" and vice versa. Reference 1. Tolman,R.C, 1962. Relativity, Thermodynamics and Cosmology. Please take a look.

Lately, I've been studying that metric INSIDE the EH. The more I get into it, the stranger it seems. It might help to know that the Schwarzschild metric inside the horizon is equivalent to a collapsing Kantowski-Sachs cosmology. At a fixed time r, the universe is an infinite cylinder RxS^2; the radius of that cylinder descreases in time, and the singularity at r=0 is essentially a "crunch." There's a nice paper by Krasnikov at arxiv.org/abs/0804.3619, published in Gravitation and Cosmology 14 (2008) 362, that you may find helpful. Steve Carlip |
