It's encouraging to see that physicists still work on common sense interpretations of QM like the Bohmian version. Tackling the issue of entanglement is not easy. Shouldn't it be worthwhile first to clear the principles of QM in the Bohmian version? Like: how does the state vector relate to the particle, how could we represent planck's quantum of action...?

Physicists have become too obsessed with the idea that everything must be "quantum" something, including gravity. Quantum behavior involves individual particles that are disorganized. Gravity involves groups of particles that are organized.

Looking at the concept of other dimensions with different characteristics than the traditional Euclidean dimensions is more likely to produce a Unified Field Theorem than is quantum physics.

An ultimate evidence for quantum entanglement would be a quantum computer that fulfills huge promises.

So far, I do not exclude the possibility that apparent symmetry and EPR can be alternatively explained just as consequences of inappropriate mathematics, cf.

An analysis in terms of cosine transform shows that h_bar is not necessarily related to the imaginary unit.

John v. Neumann admitted in 1935 having lost his belief in Hilbert space. Already in 1932, Hermann Weyl did not have an explanation for PCT symmetries. Who is interested in more details and more recent arguments?

Very interesting article. It is satisfying to know some researchers are pursuing alternate paths to 'explain' quantum mechanics. A theory that baffles everyone as to what it means is limited.

This theory must of course be supported, in preference to its competitors, by empirical evidence if we are to give it credence. The fact that it emerged from a different mathematical approach than that used by Bohm may be suggestive but adds little real support.

In the article we have this quote: 'If we know all these variables, then the equations of Bohmian mechanics can tell us how particles will move.....'

Is there an example where we know any of the variables that supposedly quide the pilot wave?

reasonmclucus....... You say .....Gravity involves groups of particles that are organized,sure !

Of course ,the complexity is incredible because the number of combinations is important.

It will interesting to do the link with the Spheroidal comportment ,mathematically ,physically and evolution....
