# Speed of Light and distances [closed]

that if for some reason, the speed of light is $c =300,000 Km/s$, they say the distance to any other galaxy is let's say

 50 light years


Supossing we can travel at a speed of:
$c^2$, $c^3$, $c^4$ and $c^5$..

How is this time reduced when traveling at this speed (50 light years)?

Might be better suited as a (silly) question in the physics SE. –  Carl Brannen Apr 15 '11 at 22:37
$c^2, c^3, c^4, c^5$ are not velocities. –  Qiaochu Yuan Apr 15 '11 at 23:02
Nothing can go at the speed of light, except light itself. And nothing can go over it. According to Einstein, anyways, and he always was a bit weird. :) –  muntoo Apr 16 '11 at 2:29
Well, I was asking, and supossing, we do not really know if there is something that could travel faster than light –  cMinor Apr 16 '11 at 3:26
