Hopefully you will have read and realized the drawing you are showing on screen may on may not happen.

The pattern will collapse to a very different one if you try and measure anything.

It's one of the weird things about Quantum Mechanics that measurement itself can change things.

That is the most tested experiment in science and there is no easy answer I can give you without talking about Quantum Mechanics.

The image you have put on screen is only one of two possibilities and it will only occur if you aren't measuring anything.

So me trying to answer at your level of layman physics .... I can't answer it because lots of weird things can happen in that picture.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
