'Absolute' is a dangerous term in cosmology, because relativity says, 
that space itself is not absolute.

IOW: relativity requires a reference to something, if you like to define 
movement (in respect to that something).

Space itself cannot be used, because relativity says, that absolute 
space does not exist.

So, something else is required.

But what shall we take???

I assume, that the observer can be used and actually is used as 'base', 
from where the universe is observed.

But that would make it impossible to measure the state of motion of the 
observer, because the observer does not move in repect to himself.

If now the observer rotates (unknowingly) he would see the universe 
rotating the other way round.

Since what we call 'universe' is only a subset of 'everything in 
existence', there are possibly 'sub-universes', which seemingly rotate, 
while that rotation is only an optical illusion, caused by the movements 
of the observer and the finite speed of light.
