A wrinkle in space-time: Math shows how shockwaves could crinkle space

A wrinkle in space-time

Mathematicians at UC Davis have come up with a new way to crinkle up the fabric of space-time — at least in theory.

“We show that space-time cannot be locally flat at a point where two shock waves collide,” said Blake Temple, professor of mathematics at UC Davis. “This is a new kind of singularity in general relativity.”

The results are reported in two papers by Temple with graduate students Moritz Reintjes and Zeke Vogler, respectively, both published in the journal Proceedings of the Royal Society A.

Einsteins theory of general relativity explains gravity as a curvature in space-time. But the theory starts from the assumption that any local patch of space-time looks flat, Temple said.
