Hi I am curious about a few things i have read about light and would appreciate some help. First of all to my knowledge the speed of light is 186,000 mps and of course its impossible to exceed or reach the barrier of light for any other object other than light. But im curious as to why lights limit is only 186,000 mps and not faster, aren't photons weightless and would not have any resistance while traveling through space? Is there some sort of universal constant that cannot allow anything to achieve speeds higher? Help would be greatly appreciated.
