> Why does pilot wave theory violate locality -- does it assume that the pilot waves travel faster than light?

Yes. The pilot wave at any given point can be affected instantaneously by changes anywhere else in the universe.

[kgwgk]

But in this regard the pilot wave is not different from the standard Schroedinger’s wavefunction, is it?

[pdonis]

No, it isn't. Both are interpretations of non-relativistic quantum mechanics, and in non-relativistic QM there is no speed of light limit.

Schroedinger’s wavefunction isn't sufficient in a relativistic context

[kgwgk]

True. To be fair, it's true that the relativistic extensions to Bohmian mechanics are not as advanced as for the "standard" theory. But they are not necessarily impossible and the requirement of a prefered foliation may not be so unacceptable if the history of the universe goes back to a singularity (so there is a "local time since singularity" that gives somes sense to the idea of simultaneity).

[MiroF]

I am not very familiar with Bohmian mechanics/Pilot wave theory, just wanted to make sure what the schro eq is and isn't was clear to everyone
