QM and SR
- Jeffrey Barrett. On the Cognitive Status of our Best Physical Theories.
- QM and SR not consistent.
- Under SR, there are two space-like separated events e1 e2 with no canonical temporal order.
- There is an inertial frame where e1 is earlier than e2 and another one where e2 is earlier.
- What if e1 and e2 are two measurements performed on an entangled system? The resulting state will depend on which measurement is performed first, but there is no fact of the matter!
