Thanks for the response North. I'm not sure however why it couldn't exist.
Good question Dipayankar, I don't know. I guess I envisioned that at c matter would become ultimately flat and therefor 2 dimensional. And maybe if it started going slower c it would perhaps ripple or curve losing its flatness and again have the 3 dimension of L,W,H. Again thanks.
