"If collapse actually worked the way its adherents say it does, it would be:1. The only non-linear evolution in all of quantum mechanics. 2. The only non-unitary evolution in all of quantum mechanics. 3. The only non-differentiable (in fact, discontinuous) phenomenon in all of quantum mechanics. 4. The only phenomenon in all of quantum mechanics that is non-local in the configuration space. 5. The only phenomenon in all of physics that violates CPT symmetry. 6. The only phenomenon in all of physics that violates Liouville's Theorem (has a many-to-one mapping from initial conditions to outcomes). 7. The only phenomenon in all of physics that is acausal / non-deterministic / inherently random. 8. The only phenomenon in all of physics that is non-local in spacetime and propagates an influence faster than light.WHAT DOES THE GOD-DAMNED COLLAPSE POSTULATE HAVE TO DO FOR PHYSICISTS TO REJECT IT? KILL A GOD-DAMNED PUPPY?"
