| What, precisely, did you expect as an answer?

| Presumably, c is a condition of space;

That's aether theory, and MMX disproved it.
Your presumption is incorrect.

You can derive the volume of a gas from Boyle's law too.
It is zero at zero degrees Kelvin.
Funnily enough, something strange happens before you
get there.

You can derive the speed of sound in empty space also,
simply measure it as you gain altitude.
Funnily enough, there is no meaning to the velocity of
sound in a vacuum.

You can derive the axis of a spinning sphere, too.
Funnily enough, it doesn't have one when it stops.

So tell me, how do you derive c when there is no property
of permeability or permittivity in nothing? Pretend there
is aether to have that property, perhaps?

Sure, you can simply use a ruler and a fast watch.

Then why claim there is?
