>>14252999>e=mc2 means that light has a mass.No, it means that shitty science make an idiotic comparison unrelated to he physical world. There is no conversion from "light" to masses and no from masses to light because light is not energy. Even the formula states that.
There is no light speed either because light did not move. What you can observe is the wave propagation speed, as always constant in an constant medium (in case of c one without matter and thereby temperature pressure etc).
