The Many-Worlds Interpretation (MWI) of quantum mechanics holds that there are many worlds which exist in parallel at the same space and time as our own. The de BroglieBohm theory, also known as the pilot wave theory, Bohmian mechanics, Bohm's interpretation, and the causal interpretation, is an interpretation of quantum mechanics.In addition to the wavefunction, it also postulates an actual configuration of particles exists even when unobserved.The evolution over time of the configuration of all particles is defined by a guiding For this ontological continuity, it seems to be a good candidate for Topoi interpretation of QM. Bohms theory says that its both: an electron is a particle with a definite trajectory, but this path is governed by a wave upon which the electron rides.

If Bohmian mechanics can account for something quantum, it can do so in a completely exact and explicit way, because Bohmian mechanics is an actual physical theory complete with equations of motion. Bohmian mechanics does not account for phenomena such as particle creation and annihilation characteristic of quantum field theory. This is not an objection to Bohmian mechanics but merely a recognition that quantum field theory explains a great deal more than does nonrelativistic quantum mechanics, whether in orthodox or Bohmian form.
