Back when we wrote about Cramer earlier this year, he was struggling to come up with a measly $20,000 to fund a high-risk experiment that would demonstrate, as he puts it, "signaling, or communication, in reverse time." Cramer could be wrong, but he ain't no crackpot; he's a physics professor at University of Washington who seems sincere in proving (or disproving) this testable idea with a simple experiment. Turns out, a lot of people really sympathized with the guy, and ponied up their own money. And why not? After all, it's going for university research (and this article even tells you how to donate).
