um, i think physists haven't yet truly discovered whether or not light has mass....that is, i think they're still perplexed as to whether light's "particles" or "waves"......i'm not 100% sure on this though

and yes, it does seem rather perplexing.....but all i can assume is that you would "SEE" it appear faster, because you "SEE".....if you moved at the speed of light, would it not be safe to assume you wouldn't see.....hence, as you still would "SEE" it would appear faster.......if you get my drift
