I don't think you're correct. I've been looking into domain walls and d2-branes.

I don't think one exists. How about an energy-momentum tensor? Perfect fluid with zz having no interaction with xx or yy components?

Nordstrom-Reissner solution? I looked, but couldn't figure it out. Would a perfect fluid solution exist with diag(\rho, p, p, 0) you think?

Is it possible for an EM stress-energy tensor such as this: [PLAIN]http://www3.telus.net/public/kots1906/emtensor.jpg to exist, where \sigma_{xx} = \sigma_{yy} ?

Absolutely none whatsoever.

I know where we can put this rod!

The fully contracted Riemann tensor, called the Kretschmann invariant scalar, of the Schwarzschild metric will reveal the singularity at r = 0. K == 48 m^2 / r^6. How do we know that r = 0 is a true singularity? Scalars are invariant under a coordinate transformation. Thus, a singularity exists...

Hoku, As easy as this may sound for me to say: Go grab an introductory book about General Relativity and start learning the MATH. Without knowledge of the MATH, you will have absolutely no understanding of GR. But, I think you need to grab yourself an introductory physics book to review basic...

I'm no longer responding to this thread. I really think Hoku is trolling now. All of the mumbo-jumbo metaphysics he throws in here along with legitimate GR contributions from other forum members just doesn't sit right with me. Good luck.

No philosophy here. Just your lack of understanding GR in a mathematical manner.

I think the problem you have is that you're thinking too much of Newtonian gravity and somehow this still exists as a force in general relativity (GR). In GR, gravity is a purely geometrical/stress-energy construction. There are no "forces" involved.

Spacetime does end. That's why its called a singularity.

Just look at the Kruskal diagram. Learn how to interpret it and it tells you everything you ever wanted to know about the spacetime near a BH.

It doesn't work.
