I mean - is the Universe really expanding just because the red shift of light emanating from a known galaxy has red-shifted further? And when we can no longer observe the other galaxy that is moving away from us, is that because we don't have the instrumentation to detect lower and lower electro-magnetic frequencies?

And, what is dark matter? Is dark energy the the counterpart to E-MC^2?

Speed of light (in a vacuum) is a constant therefore relative to everything , however there is no reference frame that can be applied IIRC Newton & Einstein stated this (although I may have butchered it somewhat)

Point 2 those bloody turtles again
