In this context, this is clearly false. Newton proposed action at a distance, but Einstein’s proposal was a local theory. Please be...

Note that this centripetal force (inward proper acceleration) is given by the spring acting on the mass (not the other way around). The...

To explain this further, let’s consider a simple mass-spring accelerometer attached radially on a spinning wheel. The mass is deflected...

Or zero-postulate derivations (not what they call themselves) that don’t assume either postulate and simply use experimental evidence...

You're the one that should be answering that question, since you're the one that made the claims about the ring laser gyroscope. If you...

By changing ##\vec a##. The acceleration is different in different frames.

No. The local centrifugal force does not have a cause. It is not a physical thing subject to cause and effect. It is purely math. It can...

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...
