Is it possible to tell with certainty whether μ and ε for vacuum change over time within a very long period of time?
I know that we are measuring a space expansion, and we can tell that not objects are moving away from each other, but the space itself expands.
However, this seems to be similar to spacetime curvature caused by gravity, and this doesn't change the properties of vacuum.
