It's happening all the time, every time you have more than 1 light source. I don't sense any warping of the time/space continuum; any spatial/temporal shift.
It was a long time ago now but if I remember my physics lesson... two photos traveling past each other are still traveling at light speed relative to each other. That's the messed up bit about relativity if I remember right.

Someone correct me if I'm wrong

This is a really interesting discussion that is going on in the scientific community. Is Einstine wrong about the speed of light? It's so interesting to watch science at work here.. evidence is brought to the fore that significantly challenges our understanding of the universe and everyone seems excited about it. It'll be interesting to see what they uncover... is it a measuring error or something else?
