I'm really kind of serious here. I mean, if the SOL is so-and-so, it must be traveling relative to something which serves as a baseline for measurement. Was this settled at some point? I mean, like, was it determined to be the aether? Or maybe it travels relative to all the mass in the Universe?

If you are at peace, you should be ashamed.

The speed of light is a constant, irrespective of which inertial frame it is measured in. You can use any inertial reference frame as the "something" which the speed of light is measured against. The aether was originally intended to be that "something" against which absolute speed was measured; SR rendered the aether worthless for this purpose.

Hence the red shift for receding galaxies. With you as a teacher, and Valev as a student, I don't think a lot will be learned.

That does seem familiar now that you mention it. Haven't thought too much about SR in a long time. Been off in the cybernetic world.
