The more I learn about light the more I realize, man, we don't know anything about light... It's just bizarre... a particle has it's own proper time which slows down as you speed up. But at the speed of light... there's no time. That's bizarre ... that we can, right now, as you know, see - interact with the light that has come from the birth of the universe. So ... from our point of view, that light traveled for 14 billion years but from the point of view of the light it's the moment of creation.
