Nope, I avoided it to make my theory a real attempt at starting from scratch. We never had it at school, and I never did it at college. So I tried to work out the whole of science from a blank page. But that doesn't matter, it was actually a good idea. Besides, fixing the electron actually removes a particle from my atom. So it makes my atom simpler. It already had holes in it, I put an extra particle in there as an electron because science had an electron mass. I now have an electron negative mass, but being as mass isn't understood, I don't mind having a different mass. Gravity in a hole must be mass so my reversed version works fine.
