in thread [OT] A prediction.

Given A and B are at a fixed distance, then if the light coming from A arrives at B sooner today than it did yesterday (which it would because it's traveling faster), then A will seem closer to B than it did yesterday.

Ignoring that the ratio between one day and 13 billion years is such that we wouldn't be able to detect the difference on human life scales, even if we had some means of calibrating the measurement; what is a "fixed distance"? Given, as you said, "we no longer have a standard for distance".

But what if the speed of light was proportional to the expansion of the fabric of space-time?

In the end, there's little point in arguing it; because there is (yet) no mechanism to test the theory.

But that's true for a whole bunch of other stuff also: https://en.wikipedia.org/wiki/String_theory

    Then I don't think we'd be able to measure that.

      We can't measure Dark Matter or Dark Energy; it hasn't stopped us inferring their existence; or postulating theories based up them.
