Hello there

Well here is my theory backed up by some logical explanations. First of all light does have mass. It is impossible for anything not to have mass. The first argument said that if it had mass and traveled at 300 000kmp/s it would rip through you. Wrong... light isn't something physical it is purely energy passed from one photon to the next. The speed of light is the rate it transfers across. Even if it is purely energy it still has mass. This is proved when light is pulled into a black hole. When light is pulled in to a blackhole it bends and .........anything that is in an arche is under constant accel. When something is under accel. it's mass is going to increase. Thus if light had no mass the equation would be void.
