Some other comment said that the electron does not interfere with itself in single slit. Is this true? why does the probabilistic nature of the electron only begin once there are multiple slits? what if you have an infinite set of slits, does the Electron interact with all of them? If so what if the slits are angled or have different sized gaps? what if there are curved slits? do the electrons still behave in a wave pattern or does it behave in a particle pattern? what if the half the probe wall is brought forward and the other half backwards and then a another double slit experiment is placed at a 90 degree angle there and the electrons are observed? does the electron being observed (by a small light wave) still behave as a particle and have changed angles by 90 degrees after being observed? is it possible then to turn the electron 180 degrees and have it interfere with electron pattern from the original double slits? what happens if the wave pattern meets particle behaviour now that they are at the same frequency. Does what happens with light and light destructively interfering with it self also happen here. Is the momentum equally split between slits or is it based on which slit the electron went through? is the momentum split probabilistically? is it then possible to have momentum split so small that the velocity results in a slit having to cross a Planck length in a magnitude of time greater than a couple of seconds? If so could we observe that slit seemingly teleport across Plancks length?
