While there may be no such thing as absolute linear motion, there may be

There is such a thing as a rigid body which conserves
angular momentum much like an elliptical orbit.
Imagine an English bobby with the big heavy hat in a universe that is
otherwise empty...
OOps! Ya just killed the goose.
<<Newton recognized that the law of
inertia is unsatisfactory
in a context so far unmentioned in
this exposition, namely that it gives no
real cause for the special physical
position of the states of motion of the in-
ertial frames relative to all other
states of motion. It makes the observable
material bodies responsible for the
gravitational behaviour of a material
point, yet indicates no material
cause for the inertial behaviour of the mate-
rial point but devises the cause
for it (absolute space or inertial ether).
This is not logically inadmissible although
it is unsatisfactory. For this reason
E. Mach demanded a modification of the
law of inertia in the sense that the
inertia should be interpreted as an
acceleration resistance of the bodies
--> against one another <--
and not against "space". This interpretation
governs the expectation that accelerated bodies
have concordant accelerating action in the same
sense on other bodies (acceleration induction).
This interpretation is even more
plausible according to general relativity
which eliminates the distinction between
inertial and gravitational effects.
It amounts to stipulating that, apart
from the arbitrariness governed by the
free choice of coordinates, the g μ v -field
shall be completely determined by
the matter. Machʼs stipulation is favoured in
general relativity by the circumstance that
acceleration induction in accordance with
the gravitational field equations really exists,
although of such slight intensity that direct detection
by mechanical experiments is out of the question. >>

Sue...
He doesn't know he is rapidly spinning like an ice skater
until he takes off his hat and tries to hold it as far in front of him as he
can reach. It flies out of his hands.
It appears the bobby was spinning relative to absolute space. This thought
experiment shows that rotation can be both absolute and relative. Linear
motion appears to only be relative.
If this is true, how would this exception to Relativity affect the Cosmos
and particle physics.
