I always wanted to do some experimenting on the fringes of quantum theory and there’s nothing more fun than looking at Young’s double slit experiment in a new way. So here goes, let’s brainstorm. Let’s forget math for a minute and think for a minute at the experiment’s result – it appears that by shooting particles one at a time (photon, electron, you name it) in that scenario the result points as if the particle interacts with itself. How is that even possible? No idea, so let’s backtrack a bit, starting over like a kid deconstructing a sci-fi movie, no math, no inhibitions and full drive.

Well, let’s have 2 screens, one as a barrier and one for measurement, like a photographic screen that shows where a particle will impact it. The barrier will have 2 slits through which that particle can pass, and we shoot a couple of thousand times a particle at the barrier and we look at where the particle impacted the measurement screen after it passed through the slits. Now, if we shoot the particles one at a time, we can observe by letting the impact points accumulate, that the screen presents a pattern like a stripped zebra, bands of less impacts followed by bands of many impacts, consistent with what would happen if there was an interference of another particle. Only we shot one particle at a time, which means the particle has somehow interfered with itself. If we try to detect which slit the particle passed, the pattern of interference somehow dissapears and the screen looks like there was only one slit open. Why?

Well, one way to make a particle exhibit a wave-like behavior is to make it move in another dimension. A point in 2D can be a line in 3D, a line in 2D can be a curve in 3D and a point in 3D can be a line in 4D. So a particle in our spacetime can be something else if we add another dimension to the mix. Let’s say our spacetime is like a sheet of paper and our particle’s path is a line on that paper, I wonder what would happen if we think of the particle as a line that only touches the paper in one point? I mean the length of the line is in another dimension, but the intersection of that dimension with our dimension is like a needle stuck in the piece of paper – it connects to the paper in only one point. Now let’s make that needle go up or down through the paper, as we progress in time. Looking at the scenario, it’s as if by going forward in time it tears a line through the paper, the line representing the path the particle takes moving through our space time. By having the needle intersect the paper at an angle and move up or down in the extra dimension, our path in the spacetime as time goes by is no longer a line but something else, a curve or free-form drawing, depending on the up/down motion and the angle. Now imagine if the extra dimension we’re picturing be independent of time, like existing in every moment of time simultaneously. Therefore we could have a different path of the needle in our sheet of paper, depending of the angle and the direction of movement in our extra dimension and if time is containedin it, it could mean every different possible path can interfere with the other path – generating a wavelike behavior in our spacetime. The paths the particle takes interfere with each other, but in the extra dimension. If one places a detector at one slit, the detector is something that’s large enough to disturb the path and since it exists in the same place for every possible future position of the particle, it interferes with that future – blocking the path and so interference is eliminated. The simple act of placing something in front of the particle generates an interference that blocks the particle from taking that particular path.

The up and down motion of the needle is quite similar to the vibration of a string, too, imagine my surprise, and there’s more. The path is dependent of the angle the needle makes with the sheet of paper and the speed of the up and down motion. The only way for the path to be a straight line is to have the angle perpendicular on the paper. Now the only way to stop the particle is to stop the interference, so there has to be a barrier existing for the entire time the particle is in motion towards that barrier. I mean, since the interference is based on the different future needles going up and down as time goes by, the wave function collapse means a barrier in front of future path of the particle, from another needle or object as a collection of needles. This, of course, assumes from the viewpoint of an extradimensional observer that the needle is stationary to the space-time and the space-time is moving or the other way around, which is rather annoying as you can imagine. Anyway, the only way the particle can interact with itself is either by interacting with its future selves or by existing as a cloud of probabilities or superpositions, the latter hypothesis making me angry by the minute, also.

Now I’m reading this again, what the hell? Am I really this crazy?
