The wave associated with the 'particle' propagates the available
slits. The 'particle' travels a single slit. The wave creates
interference upon exiting the slits. The interference alters the
direction the 'particle' travels.

I do not 'know' what a photon is or what an electron is. That is why I
continue to refer to a photon as a 'particle' which may be a directed/
pointed wave which when detected collapses and is detected as a
quantum of aether.

The same holds true for an electron. I do not 'know' if an electron is
a directed/pointed wave which collapses and is able to be detected as
a 'particle' or if it is a moving particle which has an associated
wave.

What is important is to understand the ability of the 'particle' to be
detected as a particle travels a single path.

The associated wave propagates the available paths. The associated
wave exits the slits and creates interference. It is this interference
which alters the direction the 'particle' travels.

Let's start with the basics:
- Waves propagate available paths.
- 'Particles' travel a single path.
- Waves create interference upon exiting multiple slits.
- 'Particles' are 'acted upon' by this interference and change
direction.

Y. Porat,

What you have to understand is there are different interpretations of
'QM'. The is the nonsense of the Copenhagen where all you have to do
is discuss nature as mathematical constructs like 'wave-functions' and
'probabilities' and the mathematical constructs are nature, which is
obviously absurd.

Of you can understand the de Broglie (Bhom, Einstein) definition of
wave-particle duality and de Broglie's QM understanding of nature
which discusses wave-particle duality as a physical wave and a
physical 'particle' where the wave propagates available paths and the
'particle' travels a single path:

de Broglie:

"Any moving particle or object had an associated wave."

"I had no doubt whatsoever about the physical reality of waves and
particles."

"In my view, the wave is a physical one..."

"For me, the particle, precisely located in space at every instant,
forms on the v wave a small region of high energy concentration, which
may be likened in a first approximation, to a moving singularity."

"I called this relation, which determines the particle's motion in the
wave, the guidance formula. It may easily be generalized to the case
of an external field acting on the particle."

The 'external field acting on the particle' is the interference
created by the waves as they exit the slits.

At atomic and sub-atomic scales, there are no unique objects or "single
entities", there are only multiple instances of indistinguishable identical
quantum objects. In some cases one can identify a single, unique instance of
some quantum object, but even then one cannot localize it to any specific
(exact) location, much less to two locations. Such quantum objects often
(usually) have non-zero probabilities for being at many different places
simultaneously, but they do not "exist" at ANY of them....

The underlying problem is your attempt to use words and concepts developed in
your everyday life, applying them to situations at radically different scales
where those words and concepts simply do not apply. Phenomena at atomic and
sub-atomic scales are VERY different from phenomena at human scales. Live with
it (you have no choice). LEARN from it (so far you have chosen to remain ignorant).



For the traditional two-slit experiment performed with electrons, all one can
say is that the individual electrons are detected at the screen, and the
locations of a large number of electrons detected at the screen form a curiously
structured pattern reminiscent of wave interference. In particular, one cannot
say "electrons travel through both slits". And one most definitely cannot claim
that electrons "exist" in "both slits" at "the same time" -- anyone who claims
that is either a liar, highly self-delusional, or outrageously ignorant.

For those who actually are interested, read Volume 3 of
_The_Feynman_Lectures_on_Physics_.

For those not wanting to understand nature, read Volume 3 of
_The_Feynman_Lectures_on_Physics_.

For those interested in understanding nature:

'Interpretation of quantum mechanics by the double solution theory -
Louis de BROGLIE'
http://www.ensmp.fr/aflb/AFLB-classiques/aflb124p001.pdf

"Any moving particle or object had an associated wave."

"I had no doubt whatsoever about the physical reality of waves and
particles."

"In my view, the wave is a physical one..."

"For me, the particle, precisely located in space at every instant,
forms on the v wave a small region of high energy concentration, which
may be likened in a first approximation, to a moving singularity."

"I called this relation, which determines the particle's motion in the
wave, the guidance formula. It may easily be generalized to the case
of an external field acting on the particle."

The 'external field acting on the particle' is the interference
created by the waves as they exit the slits, altering the direction
the particle travels.

In AD, the moving 'particle' has an associated aether wave.
