Dr. Hadley at Warwick has been trying to describe elementary particles by general relativity. He's had a problem that he ends up with something that conserves parity. So, naturally, he's questioning whether parity is or is not conserved in nature. Now his idea is basically that the true parity should also include charge. And that way, the famous cobalt experiment that proved parity was violated actually didn't prove it. Here are some slides on the idea: http://www2.warwick.ac.uk/fac/sci/physics/staff/academic/mhadley/heretical/parity.ppt And here is an arXiv paper: http://www.arxiv.org/abs/physics/0406118 Any comments?
