But the debroglie bohm theory is a rstorder theory i. As with the copenhagen view, theres a wave function governed by the schrodinger equation. As a philosophy buff this one seems just like the classical universe. In addition to a wavefunction on the space of all possible configurations, it also includes an actual configuration, even in situations where nobody observes it. That said its still valid since it has been deliberately cooked up, just like bm, to be indistinguishable from qm. Pilotwave theory gains experimental support quanta magazine.
