Is there anything faster then the speed of light? Can anything travel along laser light?
Maybe someday we could have space vehicles traveling by laser light at unheard of speeds. Ron T, Lehighton, Pennsylvania A: Sorry, no signal and no object travel faster than light in a vacuum. If any could, effects could happen before their causes. For example, a super-light-speed spacecraft could arrive before it started. Impossibilities would abound. Suppose I could lope along at light speed, “c”, and notice a light wave traveling beside me, of course, at speed “c”, too. That light wave will look like its standing still, relative to me. Just like the car in the next lane looks stationary when its going at my speed. But this is impossible, according to Einsteins Theory of Special Relativity. The speed of light in a vacuum must be the same (“c”) for every observer in a uniformly moving reference frame. It cant be zero for me. Therefore, I cant lope along at “c” nor, therefore, exceed “c”. What happens as an object approaches light speed? Suppose Im the pilot of a spacecraft cruising at
