Lets clear up the electron slit experiment misunderstandings.

In this experiment, when the electron is not observed, it does not split into infinite electrons. Under these conditions, essentially there is no electron. The energy of the 'electron' behaves like a wave that creates an interference pattern. When the electron is observed, it then exists as a particle (an electron is a particle) and behaves like one; i.e. it doesn't create an interference pattern. No change in energy is ever observed.
