Gordon, you can run down the rabbit hole of relativity with someone
else. The fact is your statement that "it is the inertia produced by
the centrifugal force," is wrong. Inertia is not the result of
centrifugal force, it is the reverse. You could even argue semi
successfully that centrifugal force was just another name for inertia,
but you can't say inertia is produced by the centrifugal force and be
correct.

I guess the concept of relativity is just a "convenience" for doing the math
too right?

Please do not descend any further into absurdities. Even Newton was well
aware of the relativity of motion long before Einstein came along, which is
why his law of inertias takes into account frames of reference.

Please quit before you bury yourself in a sinkhole.
