What Really Happens Beyond Light Speed
Close your eyes and let your mind drift into the strange and impossible world of faster-than-light travel. A quiet journey into what physics says happens when we break the ultimate speed limit. Mathematically, an object moving faster than light would have imaginary mass and would travel backward in time, breaking the cause-and-effect chain of the universe. Stephen Hawking's Chronology Protection Conjecture suggests the laws of physics would prevent this from ever happening. Even if light pulses can be made to appear faster than light, no information or energy travels faster. The speed of…
