Mind = Blown

I know that science is a funky thing, but I just watched this video;

Can somebody please explain this to me? I know that's not really possible as it's a bit of a mystery, but still.

Amazing.

(I know there is a YT thread, but this is more about science )

Here's a theory, the mass of electrons are so little that the mass of the metal slit causes a gravitational field which will effect the electrons course causing an interference seen on the wave demonstration?

Why does it change when it's watched then?
