We've all got crystal balls

According to a new scientific theory, humans can see one-tenth of a second into the future.

Humans have evolved that ability to make up for "neural lag," the time between light hitting the retina and the brain registering what's being seen. This allows you to catch a baseball, or duck out of the way before you've fully recognized that a brick is speeding toward your head.

The down side? This anticipatory ability also makes us susceptible to optical illusions, including sensing movement where there is none.

Bet you didn't see that coming.
