A University of Rochester study showing light that can travel backwards:

the pulse enters the material, a second pulse appears on the far end of the fiber and flows backward. The reversed pulse not only propagates backward, but it releases a forward pulse out the far end of the fiber. In this way, the pulse that enters the front of the fiber appears out the end almost instantly, apparently traveling faster than the regular speed of light. To use the TV analogy again—it’s as if you walked by the shop window, saw your image stepping toward you from the opposite edge of the TV screen, and that TV image of you created a clone at that far edge, walking in the same direction as you, several paces ahead.

What makes this fascinating to me is that this was just discovered recently. With all the brilliant minds in science, why hasn’t this been discovered before? The answer must be that the right person(s) haven’t come along yet.

This is why I think hyperspeed space travel, the kind of stuff we only see in movies like Star Trek, will be discovered and made possible someday. That includes time travel, which is another science mystery people have been working to unravel for many years. It will happen. In my lifetime? Don’t know. But it’s not if, it’s a question of when. What scientific mysteries would you like to see discovered in your lifetime?
