Has anyone done a computer simulation of the slit experiment? I predict that even in a computer simulation with balls/particles, they will create a wave like pattern due to the balls/particles bouncing. If you take something from multi dimensional space (3d+time) and project it on a 2d screen it often takes the wave form.

Bouncing on what? When you do the experiment and you send a single particle there is nothing at all between the slits and the screen where the hit is detected!

  My theory is that the balls will not all go in a straight line, some will hit the slit edge and thus not land straight behind the slit. As with light, the light will bounce around the room and come though the slit from different directions.

    That (the interaction with a single slit) would explain difraction but not the interference pattern (which appears when there are two slits).

      Sometimes the ball will go through the other slit. As with light bouncing around, it will go through both slits.

        But you will have difraction (giving a smooth distribution) when it goes through one slit and difraction (giving a infinitesimaly displaced smooth distribution) when it goes through the other. Put them together and you get more or less the same smooth distribution, not an interference.

Here's a double-slit diffraction sim I made: https://www.youtube.com/watch?v=K4KeWDfpXiw&list=PLpYLorG2XEtQKD7uHC8dK1inU6-ahSkV7 https://www.youtube.com/watch?v=K4KeWDfpXiw&list=PLpYLorG2XE... It's purely classical, based on the wave equation however.

Scientists did better. They did physical simulation of double slit experiment in macro, and recorded it on video, so you can watch it on Youtube. https://en.wikipedia.org/wiki/Hydrodynamic_quantum_analogs#Single_and_double_slit_diffraction https://en.wikipedia.org/wiki/Hydrodynamic_quantum_analogs#S...
