Is Mass the Absolute Frame of Reference in the Universe?

In summary: An object cannot possesses two different masses at the same instant...So even if an object has two different masses at the same instant, they would read them as being different masses.

Rotation is always quantifiable and detectable because of the measurable accelerations of curved motion, centrifugal force, conservation of angular momentum, etc. There is a state of no rotation in the absolute sense where these measures go to zero. From that frame of reference the universe is observed to be at rest and the galaxies, solar planetary systems, atoms, and so on are all complexly forming compound hierarchal stacked rotations in concert with the principles of curved accelerations, centrifugal effects, and angular momentum conservation. The energies required for the observed motions are all recognizable, the right amounts, and generally well accounted (as far as we understand so far...).

The heliocentric model is held because it fits our scientific theories. And by scientific theories I mean everything from geometry to F = ma to general relativity. All of these things have been tested and affirmed and so they are held to be true.

Something like a geocentric model conflicts with a lot of our scientific models, and thus would oppose many of those things that we have tested and affirmed. So we'd be saying "even though we have weighed the rock to be 5 tons and has a density of 10 g/cm^3, we believe it will float if we drop it in some water"

Are you guys suggesting there is an absolute frame after all?

No not really, I was just saying that, for example, the ridiculous system of epicycles did not properly predict the motions of the planets when compared to physical observations (made by an observer on the Earth). The heliocentric model suggested by Kepler and the one we use now, does a much better job of predicting the motions of the planets when compared to physical observations (made by an observer on the Earth).

This holds true for all other scientific theories. We make them, we test them, and if they work, then that's what we go with.

Geocentric was tested, did not work, we made another theory, tested it, and it worked (mostly, but we figured out Mercury later and now it works), thus we are going with the heliocentric model of the solar system.
