First off I think you meant light-years (which is a distance), "32.5 years" is a measure of time. If you were already 32.5 light-years (ly) from earth, oncoming light you see that passes by and heads on back behind you to earth won't reach the rest of us for 32.5 years. Whereas if we try to send you flash of light from earth, you won't see it for 32.5 years. Make sense?
Light is simply the speed of massless particles, and since light was the first discovered, it's called the speed of light. If you take something that has mass and go faster (approaching this high speed), your frame of reference shifts and time slows down for you the traveler. Which is what I think
@lgbasallote was trying to get at. :-)
Interesting FYI: Mass is now thought of as interactions with the Higgs field. As of this summer, the standard model is now a full-set. But there's one issue with that, gravity & the concept of space-time. This is why so many physicists are looking for this holy-grail unified theory that connects it all together mathematically.
