With an atom there is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons. I'm sure that there's a reason I just want to know why so I can put it behind me, but why is it we don't believe that the sun is possibly positively "charged" and the core of the earth/planets is negativly charged and the matter surrounding the core and everything on the planet is positively charged, etc... in the same manner as we know atoms/electrons/ions behave?
