#1. Current in a wire emits/absorbs radiowaves likewise an electron
and these em waves (not the electron) will cause an interference
pattern therefore the 2 slit experiment is MEANINGLESS.

#2 No one knows the true difference between an diverging em field and
em wave. The most accepted thesis is the same as comparing the sun (em
field) to a single ligth beam (em wave).

#3 Same as an em wave, the electron's em field should cause
diffraction through the 2 slits.

#4. Neutrons and neutral charges although neutral should also have em
field or a gluon field (which they say is similar to light but a force
of shorter distance).
