World Quantum Day is April 14th, and as such I’d like to post this idea.
Dark energy and dark matter – the entire dark sector – is composed of ‘quantum mechanics’.

This is pretty far out, but it is World Quantum Day!
Further details/assumptions.
- QM is de Broglie / Bohm mechanics or some similar phenomena
- This requires a guiding potential, and every other potential we have found needs a field.
- This field sticks around matter (EG dark matter),
- Some leaks out, becomes free, which is dark energy.
Expanded…
QM is de Broglie/Bohm
A popular enough opinion, but in this case perhaps we would need the wave function to live in 3D space, instead of that pesky Hilbert one. The wave function in proper de-Broglie Bohm has no mass, obvisously, so this is really a de-Broglie Bohm LIKE theory.
Guiding field
The Quantum Potential doesn’t feel field like a normal field – it’s more of a steering thing, but if you look at Couder/Bush experiments and theory, it’s possible for this guiding wave function field to be a real valued, normal excitation, which instead of guiding particles with its strength, guides them with its form.
Wave functions hang around matter
Duh – that’s the point of QM! When you think about it though, this sort of idea would require the wave functions to have a mass of up to 100 (average is about 6) times the mass of the matter they control. Furthermore, this QM wave function field would have more mass the more rarefied the baryons are. Think of a QM system (single atom) needing more energy to probe larger spaces around it to ensure QM behaviour still happens. Of course, at some point, matter will become too rarefied to support QM, at which point QM might break down. Since DM density is typically GeV/cm3 and DM seems to hang on until baryon densities are lower than that, in ordinary laboratory matter, (ie a 1cm lump of steel), ‘DM’ Quantum waves might only have a mass of a few hundred GeV, undetected in terrestrial experiments. But rarefy that lump to say 1GeV/cm^3 and the QMDM will start to out mass the matter. Where does the QMDM energy come from? It comes from the QM waves (’empty Bohm waves if you will) around us. This QMDM is extremely reactive to matter – it’s dragged along (hence Renzo’s rule from MOND) and thus forms dark matter.
Dark Energy
But think of what happens at the edge of a galaxy. The matter there gets rarefied to the point of not being able to keep the QMDM energy around, and some of it slowly leaks out, providing for dark energy to emerge as a significant energy in the as the Universe ages past a few billion years old.
Rather crazy?
Pointing out that looking for particles as the source of the dark sector is kinda limiting. I also do personally back de-Broglie Bohm theory for QM, and an energy content to quantum mechanics. Considering QM as requiring energy to function is IMO not all that big of a stretch.
I like Quasi Steady State Cosmology with an added Sink. In the STOE, the particles of mass cause superluminal waves (after Newton) in the plenum (aether without particles). Thus, the prime problem with Bohmian mechanics (the origin of the guiding waves.
De Broglie Double solution theory is an effective theory. Its solitons are quasiparticles of the effective field. Guiding quantum potential can be related to the effective metric – https://youtu.be/xi_2xvNZZJo
