In a double slit experiment with a C-60 molecule the Copenhagen interpretation of QM is the C-60 molecule creates the interference pattern in and of itself. de Broglie Wave Mechanics is a more correct understanding of the physics of nature. The C-60 molecule has an associated aether displacement wave. 'Interpretation of quantum mechanics by the double solution theory Louis de BROGLIE' http://www.ensmp.fr/aflb/AFLB-classiques/aflb124p001.pdf "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." "This result may be interpreted by noticing that, in the present theory, the particle is defined as a very small region of the wave where the amplitude is very large, and it therefore seems quite natural that the internal motion rythm of the particle should always be the same as that of the wave at the point where the particle is located." de Broglie's definition of wave-particle duality is of a physical wave and a physical particle. The particle occupies a very small region of the wave. A moving C-60 molecule has an associated aether displacement wave. The C-60 molecule enters and exits a single slit in a double slit experiment while the associated aether displacement wave enters and exits multiple slits. The wave creates interference upon exiting the slits which alters the direction the C-60 molecule travels. Detecting the C-60 molecule causes decoherence of the associated aether displacement wave (i.e. turns it into chop) and there is no interference.

Although a photon is a quantity of energy emitted or absorbed by a given object (electron); a quantity of energy is not a particle. glird

Not all properties of the assembly are exhibited by the constituents. Temperature, for example, is a property of a large sample of gas molecules. An individual gas molecule does not have a temperature. > > < Thus, when I measure the wavelength of light, is it a fair statement > to say I'm detecting light as a particle? > > > Obviously not. > > < Light has a litany of properties, including some that are particle- > like and some that are wave-like.

Waves inherently do not exhibit this behavior. Waves deposit energy continuously. What you are doing is similar to what I said below about using the word "particle". You are calling photons waves, but in so doing completely redefining what the word "wave" means, compared to what it meant in the 19th century. Why not just call them photons, rather than trying to massage the meaning of "particle" or "wave" so that you can shoehorn photons into one of those two categories? More importantly, why does it make any sense about whether it is better to massage the meaning of "wave" than it is to massage the meaning of "particle"? > > < But photons behave in ways that are unlike a usual particle > description. > > > That's because they aren't particles of matter.

Yes, it is. It is COMPLETELY compatible with the C-60 molecule always being detected at a single slit when a detector is placed at the slit(s). In fact, the current model says that's exactly what should happen. > > > Your statement that the photon is always detected as a particle is > > still factually false. > > Your 'understanding' of the physics of nature is more incorrect than > de Broglie wave mechanics. > The "understanding" of nature is not the question put here. It is whether it is an experimental FACT that photons are always detected as particles. That statement is factually incorrect, and has nothing to do with the "correctness" of an "understanding". |
