[QUOTE="BigJDubs, post: 5491726, member: 596078"] Hi guys. I've been a long time lurker (always enjoy reading the posts here and learning lots!), but a recent question that came up 'around the watercooler' prompted me to sign up and ask the experts. Humor me, as none of those who got into this debate (myself included) are experts on this stuff, nor do any of us have any formal training beyond our own hobbyist interest and readings, but all have curious minds none the less. Suppose you're in a car traveling at that speed of light (yeah I know, not possible, but a fun thought experiment anyway so stick with me). Its getting dark (hah! see what I did there?) and so you flip on your headlights. Up ahead you see a stop sign... the question is, what color is the sign? Is it red, or... ? Does the color change as you get closer? Further away? Thanks for the learnings in advance :) [/QUOTE]
