Apparently not according to Skip Garibaldi, a mathematician who decided to actually do the math and write a paper about his findings.

“Garibaldi did the math to disprove the theory, which involves a mysterious structure known as E8. The resulting paper, co-authored by physicist Jacques Distler of the University of Texas, will appear in an upcoming issue of Communications in Mathematical Physics.
‘The beautiful thing about math and physics is that it is not subjective,’ says Garibaldi. ‘I wanted a peer-reviewed paper published, so that the scientific literature provides an accurate state of affairs, to help clear up confusion among the lay public on this topic.’ "
