What is the collapse in Bohmian mechanics?

2018-03-1301:47

9. In standard quantum mechanics the wave function of a system collapses upon observation. I always thought the collapse of the wave function was something essential.

The logical truth is definitely of philosophical significance (at least insofar as it relates to the ontological nature of the particle/wave itself) but it's certainly true that the verification of such an ontology is contingent on external empirical considerations. Loving these discussions!
