Has there ever been found some relation between some properties of light (its speed, how mass increases as an object nears light speed, the degree to which light is bent by a gravity field, possible energy levels of photons, etc.) and the equation? Or rather, are there any phenomena ascribed to light/photons that can be reduced to or is described by the equation? I know this is a pretty vague question, but any answer would be welcome. :wink:
I would still like some more answers on my infinity thread too.
