Time-Travel Proven Impossible

Researchers from the Hong Kong University of Science and Technology measured the speed of a single photon, the smallest unit of light, and claim that it cannot move faster than the speed of light (in a vacuum). Not only does this prove Einstein's assertion that nothing can move faster than the speed of light, it also eliminates the possibility of time-travel.

Published in the U.S. journal, Physical Review Letters, the study concluded that "an effect cannot occur before its cause" -- a rule we all learned in grade school (or should have).
