Let's discuss 'dark matter' for a moment. Dark matter exists in the vacuum of space and creates a ripple when galaxy clusters collide.
In the same way that an explosion in space will send out dust and debris, the collision of galaxies sends matter and dark matter in all directions.
How does dark matter not exist in the vacuum a double slit experiment can be performed in?
It does, it just doesn't interact enough to make any observable difference in lab experiments of that nature.
Is dark matter virtual? Does dark matter have more of your absolutely absurd ridiculous notions associated with it all in order for you to remain ignorant of understanding what occurs physically in nature?
You obviously haven't understood what 'virtual' means. Clearly you didn't go and do any thinking or reading, even after I highlighted your ignorance and mistakes.
'Virtual' is a statement about whether or not a particle is obeying a specific relation between its mass, energy and moment. All particles can be both real and virtual, in the same way an object could be hot or cold, a photon can be both on-shell or off-shell, otherwise known as real or virtual.
You don't seem to grasp dark matter well either. Dark matter is particles which only interact via the weak force and gravity. We already know of such particles, the neutrinos. Thus the properties of dark matter aren't anything new, it's just there's more particles with such properties than thought in the 1950s.
How does this same physical phenomenon which occurs when galaxy clusters collide not occur in a double slit experiment? How are galaxy clusters able to create a ripple in the dark matter when they collide at the same time a particle moving through the dark matter in a double slit experiment does not create a ripple in the dark matter? In a double slit experiment, the moving particle has an associated dark matter displacement wave. The particle enters and exits a single slit and the associated dark matter displacement wave enters and exits both.
Because galaxies have masses of trillions of stars and thus have lots of gravity to pull the dark matter around. In the lab the dark matter doesn't interact enough via the weak force to have an effect. For example, right now there's trillions of neutrinos passing through your body but they don't do anything because they only interact via the weak force and gravity. It takes huge experiments involving billions of tons of ice (like the neutrino telescope at the South Pole) to detect even a few dozen a year, that's how infrequently they interact with normal matter.
You haven't bothered to find out the details and you're getting indignant with me (and mainstream science in general) for your own failings. Grow up.
Where the concept of non-baryonic dark matter is incorrect is there is no such thing as non-baryonic dark matter gravitationally bound to matter.
Neutrinos are non-baryonic matter which only interacts via weak and gravitational interactions and they can be gravitationally bound to baryonic matter.
Like I said, the properties of dark matter aren't new. We have examples of such properties in observed particles already. The novel issue is that originally they were thought to be only a small part of the universe, now it seems they are a significant part.
The reason why galaxy clusters are able to create the ripple is because the galaxy clusters are not moving with non-baryonic dark matter. The galaxy clusters are moving through and displacing the aether.
And you have less evidence for this than dark matter physicists have for dark matter. You can't simultaneously whine about dark matter and virtual particles while claiming utterly unjustified, untestable things.
The reason why a particle is able to create an interference pattern in a double slit experiment is because the moving particle has an associated aether displacement wave.
For which you can provide no model, no evidence, no testable predictions.
de Broglie, the person who first understood wave-particle duality, understood it correctly.
"any particle, even isolated, has to be imagined as in continuous “energetic contact” with a hidden medium"
The "energetic contact" with a hidden medium de Broglie refers to is the displacement of the aether by the particle.
And Newton believed in Bible codes and alchemy, should we all too? Science moves on, evidence is gathered, predictions tested, models refined or remade.
You are intellectually dishonest for whining about things you don't understand and refuse to read about. You're hypocritical for whining about the supposed untestability of virtual particles while offering no testable predictions of your own claims. And finally you're just plain ignorant about science and the scientific method.
