It isn't experiencing "centrifugal force". It's experiencing internal forces between its parts because they push on each other. Those...

As I already told you in a previous thread, Centrifugal force is not something that can be experienced. No experiment can ever measure...

IMO, it is false that the Michelson-Morley experiments were artificially designed to give the result supporting the postulate of a...

It isn’t relevant and it isn’t correct either. Some postulates are facts. Being a postulate doesn’t make something a fact, but it...

While a postulate is not a fact, it we can make predictions as what would happen if it were true. This, in turn allows us to devise real...

In the context of GR, the following invariant physical definition of unaccelerated is taken: a body is unaccelerated (zero proper...

This thread is reopened. Participants are reminded that all posts must be consistent with the professional scientific literature.

Indeed. So when we find that our concepts do conform to objective reality we can reject the assumption that they are imaginary. In...

And so, a model (motivated by physically observed phenomena) and a set of tools to analyze the model lead to testable predictions, which...

Because the light moves at ##c## with respect to any inertial observer.

I'm not sure what you mean. Surely the pulse is always moving from one part of the apparatus to another? You certainly can consider a...

I wouldn’t read that into the question. This question can be answered in GR (as I did above) even though GR is non-Machian

Geometrically it is for the same reason that an angle requires two straight lines but a curved line can make definite angles with...

Centrifugal forces cannot be experienced. They produce no measurable effect. They are only mathematically inferred due to motion.

Hi. I’m studying GR on my own. Perhaps we could talk privately? I’ll sent you a DM.
