Required: x Double Slit Experiment
The implication of the x Double Slit Experiment and the x Wave-particle duality is that the particle has interacted with itself. But how can this be possible?
In order for an interference pattern to appear, the photon would need to go through both slits and interact with itself.
So the question becomes: what would happen if there were 3 slits.
Well, we would of course see an interference pattern involving the three different paths possible to take by the photon, which again means that the photon has gone through all three in order to interact with itself.
So, what about 4 slits, or 5? The photon would need to travel through all five.
Now, lets expand this thinking. What if there were infinite slits?
The answer is of course the same, the photon would need to go through all of them in order to collapse the most likely interference with itself.
What does infinite slits look like? Well, imagine them with no distance inbetween. This would just be removing the wall altogether.
We can go one step further and imagine not only infinite slits, but infinite walls as well.
This is of course just another way to describe empty space.
The implication of extrapolating the double slit experiment to inifinity is to realize the true nature of particles.
They don’t have a single trajectory through space, but are going through all possibilities at all times and collapsing upon the most likely interference pattern.
So why do we experience a single trajectory?
Maybe because we are navigating a 4-dimensional timeline through a 6-dimensional 3x3 spacetime. (No one actually knows, this is referred to as the x Measurement Problem)
