>>72369125I can't answer all of that in specifics, but one thing I read once that really changed my perspective and kind of blew my mind is that the speed of light isn't a limit of light itself, it's the speed limit of causality, basically. Nothing can move faster than that. Light basically moves at maximum velocity possible since it has no mass slowing it down, so it's maximum speed is speed limit of the universe and reality itself. As far as I understand it, at least.
