Answer:
- the use of light travel fasters
Scientists officially announced Friday (Sept. 23) that subatomic particles called neutrinos may be passing the ultimate speed limit, zooming at a velocity faster than light. But according to Einstein's special theory of relativity, nothing can cross this barrier. So either the measurements are incorrect, or physicists must revise many trusted theories.
Turns out, the results were likely flawed, according to a growing scientific consensus some six months after the discovery was announced. Even so, here are 10 implications of faster-than-light travel.

The speed-of-light rule represents the backbone of Einstein's 1905 special theory of relativity. This law does away with the concept of absolute velocity, and instead says that motion is relative. Except for light, that is. All observers, no matter what their own speed, will measure the speed of light at a constant 299,792,458 meters per second (about 700 million miles an hour). This speed represents the fastest that anything can travel, an absolute upper limit on motion.
The new findings threaten to overturn this trusted law. "According to relativity, it takes an infinite amount of energy to make anything go faster than light," said physicist Robert Plunkett of the Fermilab laboratory in Batavia, Ill. "If these things are [moving faster than light], then these rules would have to be rewritten."
Time Travel

Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.
The new finding raises all sorts of thorny questions. If the neutrinos really are traveling faster than light, then they should be time travelers. The particles could theoretically arrive somewhere before they departed. Physicists suggest such an ability, if it really existed, could be used to send neutrinos back in time to deliver messages.
Cause and Effect

A fundamental law of physics, indeed of all science, is causality: that cause always precedes effect. This was accepted in classical physics, and the special theory of relativity took pains to preserve the rule, despite the relativity of an object's motion.
