umm, photons do not have any mass. The reason why light is affected by black holes/gravity in because of warping and curving of space - gravity is not thought to be a vector like force. Photons follow the "surface" of space-time. If curving is extremely strong as is the case with black holes...
[edit by Ivan] Speculation and fringe theory deleted. Even if you aren't promoting these ideas, they have no place in this discussion. We are only interested in determining what if any evidence for the claim exists. [end edit]

Hope that helps
this is only true if you travel below or at exact speed of light. If you go above it, time for you will go faster than that on Earth. As one can see from the link above, if you do a one year trip at 200% the speed of light, only about 7 months will pass by on Earth so time for you goes faster...
if you are able to travel faster than the speed of light, you'll enter imaginary time which doesn't exist at all, so your question becomes meaningless
