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?

I think the premise here that Einstein is using here is that your clock runs
faster if you rush towards the source of the light so there is no change in
frequency (cycles/unit of time).

If you are serious, then here is how it works. 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.

No, in SR (and GR for that matter) if you move towards a light source, it
appears to have (and in fact does have) a higher frequency. 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. Good though your intentions probably are.

Thank you. 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.
