Are you suggesting the existence of a preferred or absolute frame?
No more than you are suggesting that the shape of the water in two buckets rotating in opposite directions can both be due to the motion of the whole universe and not the direction of rotation of the individual buckets - Newton's bucket 'thought experiment'.
Einstein in his development of GR would have like his theory to follow Mach's principle but realised it was not possible.
As far as I am concerned
uniform linear motion is completely relative, but accelerated motion, including rotational motion is not relative.
Imagine a person in a box with no outside communication, but with instruments of sufficient accuracy and sensitivity.
Newton's water buckets might suffice in extreme cases - see where the water goes.
I would contend that:
- This person could not measure uniform linear motion in any direction - regard uniform linear motion as along a geodesic in curved if you must.
- This person could determine that the box accelerating linearly by finding the acceleration uniform at all locations within the box.
- This person could determine that the box rotating by finding the acceleration non-uniform at all locations within the box.
With the proviso that the accelerations could be due to gravitational fields.
Now I do not claim to be a physicist and the question of whether rotation can be absolute of not still seems vex physicists.
But the concensus seems to be that in from any practical point of view, it must be.
You might read,

Here is another, though it's outside my "expertise",
Doesn't Einstein's General Relativity violate the spirit of Principle of Relativity?On different FE models, we have you arguing for the relativity of everything and
sandokhan that Sagnac-like devices can measure absolute velocity - sure makes life interesting.
And I have yet to see any post of yours answering the topic other than:
Large formations like hurricanes simply begin to manifest signs of the Machian effects of the cosmos above them.
This does not even begin to explain the four distinct situations seen on any weather map of the mid-latitudes.
Even when it comes to the ordinary weather patterns of Highs and Lows, something causes the four distinct situations observed for High and Low Pressure Weather systems,
These include the intense lows, Hurricanes, Typhoons and Cyclones, in the Northern and Southern Hemispheres.
| | Northern Hemisphere | | Southern Hemisphere |
Highs | | Clockwise | | Anti-clockwise |
Lows | | Anti-clockwise | | Clockwise |
Just look at weather maps that show highs, lows and wind directions to verify this for yourself.
