The Seattle scientist who wants to test a controversial prediction from
quantum theory that says light particles can go backward in time is,
himself, running out of time.
I guess you could say we’re now living on borrowed time,” wryly joked John Cramer, a physicist at the University of Washington. “All we need to keep going is maybe $20,000, but nobody seems that interested in funding this project.”
It’s a project that aims to do a conceptually simple bench-top test for evidence of something Albert Einstein called “spooky action at a distance.” The test involves using a crystal to split a photon, a light particle, into two reduced-energy photons that — through careful manipulation — Cramer thinks could reveal a flash of time traveling backward.
