Maybe an electron is not matter ? ?, and is something else entirely, a new type of existence. Have they tried this with other particles? What about a proton?
You don't have to be a scientific genius to know the double slit experiment.
This seems cool to me although I do not know what it means.

Yet I am still confused. Any scientific minded persons like to explain? Eg. why it is important? What it could mean? What could we do if we knew why?
