I was reading Can Bohmian mechanics be made relativistic? from 2016 that attempts to reconcile Bohmian mechanics with relativity. It’s conclusion says:
Is such a theory then fundamentally—and/or seriously—relativistic? This is not an easy question to answer, because it is not at all clear what, exactly, fundamental/serious compatibility with relativity does, or should, require.
However, it doesn’t mention anything about gravity. So I read A Pilot-Wave Gravity and the Titius-Bode Law from 2018 about reconciling the pilot-wave interpretation with the Titius-Bode Law by developing a theory of quantum gravity they call “pilot-wave gravity”.
Abstract. Since its initial proposal in 1766, Titius-Bode empirical law has remained a puzzling source of discomfort as it predicts the average distances from the planets to the Sun for no apparent reason. Using a framework analogous to de Broglie’s pilot wave theory and the self-organizing Principle of Eurhythmy, we claim that several main physical quantities describing the Solar System are quantified. Hence the Titius-Bode Law is a direct manifestation of gravitational pilot-waves at work in the Solar System.
"General relativity, on the other hand, must accept that gravitational phenomena can only be fully described if one also applies a wave model. In other words, there will be some aspects best described using general relativity and others best described using pilot wave gravity," said Castro.
Would pilot-wave gravity reconcile Bohmian mechanics with relativity? Would such a theory actually disprove Copenhagen’s interpretation?
