Backlighting....

A professor of optics at the University of Rochester has gotten light to move backwards in time, at a rate faster than light.

"It's weird stuff," says Boyd. "We sent a pulse through an optical fiber, and before its peak even entered the fiber, it was exiting the other end. Through experiments we were able to see that the pulse inside the fiber was actually moving backward, linking the input and output pulses... [snip] "I know this all sounds weird, but this is the way the world works," says Boyd."

No weirder than the Many Worlds Interpretation of Bell's Theory, which is nicely illustrated in this java-tutorial on Feynmann's Two-Slit Experiment aka The Most Beautiful Experiment in Physics.

If there are an infinite number of realities constantly coming into being, sandwiching our own, it only makes sense that some of them are going backwards! If interested, check out "What the #$*! Do We Know?" Trailer here.
