Double Slit Demonstrated for a single Neutron

Post by Dennis P Brown »

Interesting review of how the double slit experiment was demonstrated using only single neutrons without resorting to statistical methods to show the neutron's wave function went through both 'slits'. Does show that the quantum understanding of particles is the only explanation that directly works.

Just a quick follow up comment on the implications of this experiment which is rather significant and far ranging relative to the "wave" formalism that is used in quantum. While the mathematical wave formalism of quantum mechanics has certainly been questioned as to whether it is "real", rather than a mathematical formalism, these results strongly supports the reality of this wave approach. That these complex waves do represent what reality is actually occurring in nature. That is, while a single particle can't go through two slits at once, the probability wave function can and in this experiment, apparently did.

A pet peeve rant follows:
As an aside, these results really do falsify a lot of information theory that attempts to use those concepts* to explain quantum mechanical results. Like "Dark Matter", much of information theory is just baseless arguments that look 'pretty' but have zero direct experimental proof. Another reason why so much of theoretical physics is hitting so many 'dead ends'. Beauty in the math of the physics equations isn't necessarily reality and can lead one far astray.

* where all information must be based on binary information. So partial wave functions would be impossible under that approach since spin must then be whole integers that are binary at all times.

The Dark matter posit is only there to confuse the Grey matter --ie to postulate what we cannot see or measure

That which cannot be detected directly, is not...
However, it can always be given a name for the sake of complete understanding as a working model....
sasquatch, polywater, and ghosts come to mind.

What about "inter-creational dark pressure"? or "extra-creational dark vacuum" but that smacks of dark energy, another name for that which cannot be detailed or directly understood. In general, when you fully understand something you can use it for some purpose. Not only do we not understand anomalies on the universal scale, we give them names to make us feel good.

I had (but can't now resist) intentionally avoided giving my soap box opinion on "Dark Matter" but suffice it to say that it not only doesn't exist but continues to stop any real progress in solving that rather significant issue (that is, solving the "elephant in the room" problem that the current theory of gravity utterly fails on cosmic scales!)

The annoying aspect about this search for "Dark Matter" is the fact that after all researchers have continued to fail in even finding just a vague hint of the stuff, this absolute fact just drives most of them to further extreme's. So, net result to date: the vast majority of theoretical physicist continue this quixotic quest just because no one has succeed - not unlike the really useless attempts to describe the physic's of the interior of "Black Holes".

There (Black Hole interiors), even the greatest minds of physics seem to love to continue to go down that totally pointless rabbit hole. Why? Because, I guess, complex physics constructs just based on math and that will never be supported by any real experiment, can't then be disproved (or proved.) In that manner, they all look really smart ;)
