Light travels at the speed of light, and it has mass. Why else would be affected by gravity?
If light had mass e would not = mc2 and atomic fission and fusion would not be possible. See A. Einstein, a prominant patent clerk and all around great guy.

I realize that. Can you explain why if light has no mass it is affected by gravity?
