Double-slit Experiment with Electrons
We know from measurements that there exists an electrical gradient out from Earth of +400 000 V. At a voltage of + 400 000 V far out in space, space must contain a cluster of positrons (antimatter), or that it is a cluster of electrons in our atmosphere with decreasing density out of Earth (Earth's gravity attracts electrons from space). If we define the earth potential as 0 V and the number of electrons out from the earth decreases, it will give a positive charge gradient. The latter scenario seems to be the most likely since positrons would cancel out all electrons in space (e.g. solar flares).
Suppose that there is a cluster of electrons in our atmosphere when evaluating the double-slit experiment, inject electrons into a cluster of electrons. What will be the outcome? Is it thinkable that an electromagnetic wave is formed in a cluster of electrons that can explains the creating of the interference pattern on the screen behind the slits?
