I tried to understand the Bohm interpretation and this is what picture appeared to me. Please tell me if I understood something incorrectly.
All particles have definite positions and follow deterministic rules of dynamics
Any future configuration of an isolated subsystem is only dependent on initial conditions
Even slight differences in initial conditions may result in huge differences in the result.
The problem is that those initial conditions are inherently unknown. This is fundamental: even if an observer manages to measure the whole Bohm state of the entire universe, he still would not know the Bohm state of himself.
This is like making predictions about the future states of a three-body system based on Newtonian mechanics with initial coordinates known only with finite precision. Due to apparent chaoticity of the solution the possible results may be dramatically different.
Correct me if I am wrong.
