- I understand that special relativity gets rid of the idea of absolute
- 3D space and absolute time, but is there any such thing as absolute spacetime?
-
- I think what I am asking is, is there an objective spacetime fabric out there
- through which all particles move? Or does a different universe exist from the
- perspective of every particle?
-
- Um... also... how does an object "know" that it is spinning relative to
- the "fixed" stars? (Relative to the object, all it's particles are at rest
- and only the universe is spinning).
