: I totaly disagree with your pure energy theory; how do you measure the speed of light??? By the medium its travelling in. Light travels slower in water than it does in space and light travels even faster in a vaccum. SO, if you could somehow create a vaccum and ride a beam of light in the vaccum say with a solar sail then, you would indeed be travelling faster than the light travelling outside of the vaccum.

Just like gravity, people probaly never thought we could ever harnes/penatrate it. people never knew about light the same way we do now. I am convinced that are somethings moving at speeds faster than light, and why not of course we could not detect them but how can we measure it. Early people could not meause light but now we can. Only time will tell
