Think outside the Earth-box.
a)
We live in Earth- box and see that all electron's (E=h*f)
parameters become infinite ( E= ∞) in interaction with vacuum.
b)
It is forbidden by
* The Law of conservation and transformation of energy/ mass*
c)
But according to Dirac there is another box: Vacuum's holes-box (!)
with virtual negative particles (- E=Mc^2)
d)
So, thinking outside the Earth-box I can suggest that electron (E=h*f)
in Vacuum's holes-box (!) somehow can transform into Dirac's virtual
negative particles (- E=Mc^2).
This local negative energy (- E=Mc^2) for Earth's observer is infinite.
But the truth is hidden in the Vacuum's holes-box.
Without two (2) boxes the quantum phenomena will be puzzle forever.
