## Main Question or Discussion Point

i am wondering when i read about planets or solar systems that are like 1million lightyears away, those that take into account length contraction, because if the light is traveling at the speed of light then the distance it has to go will contract.

also another (possibly) stupid question: formula for length contract is like

L=Lo/sqrt of 1-v^2/c^2

light travels at the speed of light so it will be L=Lo/0 which is impossible(zero in denominator)... does that mean length can't contract when it comes to light?
