Title: Does light have mass or age?
Post by: creadyhome on 30/03/2010 01:34:36

Does light have mass? It travels at speeds which are deemed to be constant(and extreme), but Light has never torn me apart as it has collided with me. We say that nothing can travel faster than it and it has been postulated that time may slow down as you approach the speed of Light. Would it not then be forever ageing LESS than the universe that it exists in? For that matter, does time affect Light at all?

(Mod edit: Changed topic to a question.)
