It is also known as Bohmian Mechanics and the "causal interpretation."
It includes a controversial "vector potential" that travels instantaneously, violating the theory of special relativity.
It is said to reproduce all the same predictions as standard quantum mechanics and it is explicitly
non-local.
It claims that all the properties of quantum particles exist even when they are not being observed, opposed to the "orthodox
Copenhagen" view that particles acquire their properties only when being observed in an experiment.
Jean Bricmont concludes that the de Broglie-Bohm theory naturally accounts for the following:
1. The measurement formalism, including the collapse rule.
2. The no hidden variables theorems, which are explained by the contextuality of measurements and the active role of the measuring devices.
3. The apparent randomness of quantum mechanics, which follows, in a fully deterministic theory, from rather natural assumptions about initial conditions.
4. The unavoidable nonlocality of any theory reproducing the quantum prediction.
(Making Sense of Quantum Mechanics, p.291)
John Bell came to the conclusion that
local "hidden variables" will never be found that give the same results as quantum mechanics. This has come to be known as
Bell's Theorem.
Bell said that all theories that reproduce the predictions of quantum mechanics will be "nonlocal,"
