  Which is faster, light? or radio waves? Hint: Check the spectrum. Bob, this is like asking - what is faster, the lightening or the thunder? The answer is obvious. |

OK, here is the answer. Radio Waves up into into the spectrum of Microwaves travel slower than light. some more factoids. We can never see the "now" we can only see what was; i.e. we see the Sun as it was eight minutes ago not as it is "now". Light from some of the stars we see now may have begun the journey long before the world was formed. Some of the stars that produced the light may not exist today. This holds true for our galaxy only, there may be millions of Galaxys in our Universe. If we look at something in a room, we can only see it as it "was" never as it is. The sight of an object must travel to the receptor and that takes time and speed, so what we see is always "was". BTW. The speed of light is faster than the speed of sound. We see the flash of lightning before we hear the roar of thunder.
