Actually that was cast in doubt by a recent experiment. (light being particle flow) Light travels in "waves". Look for references to the "double aperture" experiment. (the results blew away a lot of what were thought to be facts about light)

Light is a very odd thing, it behaves like nothing else and seems to constantly defy attempts to write rules for it's behavior. Something very magical about that perticular chunk of the electro-magnetic specrtum. (if it even really is part of the spectrum)

For example gravity has yet to be proven to have any effect on electro-magnetic waves. Cosmic radiation zips right through anything, possibly even black holes.

What's really freaky are those "blasts" of cosmic radiation that devistate everything in their path for millions of light-years. These were discovered a few years ago. Good thing is we'd never know what hit us if the Earth was in the path of one.
