Ok there "nick tesla", the terms positive ( + ) and negative (- )denote, the flow of electrons on a conducting material.
youre actially wrong "modern science" says
Electrons are ALWAYS negatively charged.
Protons are ALWAYS positively charged.
look what i said above , i was talking about direction of flow
there is still no existing "negative charge" just flow in different directions
it shouldnt be called a negative charge if the electrons are flowing directionally
the terminology is screwed up and misleading
