So .. a quantum particle is here, and the waves are in the other universes .. 

Abstract:   http://dx.doi.org/10.1103/PhysRevX.4.041013

 investigate whether quantum theory can be understood as the continuum 
limit of a mechanical theory, in which there is a huge, but finite, 
number of classical “worlds,” and quantum effects arise solely from a 
universal interaction between these worlds, without reference to any 
wave function. Here, a “world” means an entire universe with well- 
defined properties, determined by the classical configuration of its 
particles and fields.

In our approach, each world evolves 
deterministically, probabilities arise due to ignorance as to which 
world a given observer occupies, and we argue that in the limit of 
infinitely many worlds the wave function can be recovered (as a 
secondary object) from the motion of these worlds.

We introduce a
 simple model of such a “many interacting worlds” approach and show that
 it can reproduce some generic quantum phenomena—such as Ehrenfest’s 
theorem, wave packet spreading, barrier tunneling, and zero-point 
energy—as a direct consequence of mutual repulsion between worlds.

 we perform numerical simulations using our approach. We demonstrate, 
first, that it can be used to calculate quantum ground states, and 
second, that it is capable of reproducing, at least qualitatively, the 
double-slit interference phenomenon. (end quote)

 a newly published study, physicists propose that parallel universes 
really exist and that they interact and influence one another by a 
subtle force of repulsion.

Griffith University academics are 
challenging the foundations of quantum science with a radical new theory
 based on the existence of, and interactions between, parallel 

In a paper published in the prestigious journal 
Physical Review X, Professor Howard Wiseman and Dr Michael Hall from 
Griffith’s Center for Quantum Dynamics, and Dr Dirk-Andre Deckert from 
the University of California, take interacting parallel worlds out of 
the realm of science fiction and into that of hard science.

team proposes that parallel universes really exist, and that they 
interact. That is, rather than evolving independently, nearby worlds 
influence one another by a subtle force of repulsion. They show that 
such an interaction could explain everything that is bizarre about 
quantum mechanics.

Quantum theory is needed to explain how the 
universe works at the microscopic scale, and is believed to apply to all
 matter. But it is notoriously difficult to fathom, exhibiting weird 
phenomena which seem to violate the laws of cause and effect.

the eminent American theoretical physicist Richard Feynman once noted: 
“I think I can safely say that nobody understands quantum mechanics.”

 the “Many-Interacting Worlds” approach developed at Griffith University
 provides a new and daring perspective on this baffling field.

“The idea of parallel universes in quantum mechanics has been around since 1957,” says Professor Wiseman.

 the well-known “Many-Worlds Interpretation”, each universe branches 
into a bunch of new universes every time a quantum measurement is made. 
All possibilities are therefore realized – in some universes the 
dinosaur-killing asteroid missed Earth. In others, Australia was 
colonized by the Portuguese.“But critics question the reality of these 
other universes, since they do not influence our universe at all. On 
this score, our “Many Interacting Worlds” approach is completely 
different, as its name implies.”

Professor Wiseman and his colleagues propose that:

 The universe we experience is just one of a gigantic number of worlds. 
Some are almost  identical to ours while most are very different;
    *All of these worlds are equally real, exist continuously through time, and possess precisely defined properties;

 All quantum phenomena arise from a universal force of repulsion between
 ‘nearby’ (i.e. similar) worlds which tends to make them more 

Dr Hall says the “Many-Interacting Worlds” theory
 may even create the extraordinary possibility of testing for the 
existence of other worlds.

“The beauty of our approach is that if
 there is just one world our theory reduces to Newtonian mechanics, 
while if there is a gigantic number of worlds it reproduces quantum 
mechanics,” he says.

“In between it predicts something new that is neither Newton’s theory nor quantum theory.

 also believe that, in providing a new mental picture of quantum 
effects, it will be useful in planning experiments to test and exploit 
quantum phenomena.”

The ability to approximate quantum evolution 
using a finite number of worlds could have significant ramifications in 
molecular dynamics, which is important for understanding chemical 
reactions and the action of drugs.

Professor Bill Poirier, 
Distinguished Professor of Chemistry at Texas Tech University, has 
observed: “These are great ideas, not only conceptually, but also with 
regard to the new numerical breakthroughs they are almost certain to
