Emergent quantum mechanics comes in many forms: stochastic electrodynamics ( Ana María Cetto
) , de Broglie – Bohmian mechanics (John W M Bush
) , thermal models ( Gerhard Groessing
) etc. In many of these forms of emergent quantum mechanics, particles have a physical existence and experience sub quantal movement. The paper I have just posted looks at the gravitational consequences of this sub quantal motion. An interesting finding is that while a classical Bohr hydrogen atom has a lifetime of about 10^-11 seconds, it would take that same atom 10^40 seconds or so to radiate away a few eV of energy. This indicates that the stability of the atoms is not
an indication that gravity needs to be quantized, which is antithetical to Einstein in 1916:
- “…Nevertheless, due to the inner-atomic movement of electrons, atoms would have to radiate not only electro-magnetic but also gravitational energy, if only in tiny amounts. As this is hardly true in Nature, it appears that quantum theory would have to modify not only Maxwellian electrodynamics, but also the new theory of gravitation.” – Einstein, 1916
Einstein it would seem was wrong on the gravtitational side of this.
The paper looks at possible ways to see these tiny emissions (nuclear scale emissions are higher) and thus lays out a quantum gravity experiment achievable with today’s technology.
The experimental parameter space. Most important thing to note is that this is a quantum gravity experiment with an achievable parameter space!
