all our current laws of physics have just been trashed if we can do that.

Not at all. Assume two planets are traveling in opposite
directions away from a reference point in space. With
respect to that reference point, each is traveling at
3/4 the speed of light in opposite directions. Calculate
the red shift from one planet to the other and one comes
up with a negative frequency.

We are likely to discover some day that gravity is a
function of the relative velocity of the Earth through
the ether. At least that's what my alien buddies say.
