RE: Examining life through a skeptics eyes
I should mention, before I get too tautalogical, that I haven't started my astrophysics degree yet (later this year, fingers crossed, at Melb.Uni). Accredited physicists are much better at this than me.
Radiation might be considered the simplest or purest form of information, that's pretty much all it is.
Light has momentum but no substance. All it does is tell any atomic systems that it hits (ie. matter), to get excited, it doesn't really hit them at all. Sometimes the matter gets so excited a proportionate group of electrons leaps off its other side (hence light has momentum, ref. the photoelectric effect of 1915).
The US Navy uses lasers for strategic communications (argon, I think).
driving a fast car should feel like falling off a building.
