Har Har, Yuk!

1) Why does a neutron split up into a proton and an electron when it is taken away from the nucleus of an atom?

it doesn't, so if this is a fundamental plank of your new world view, you are wrong, and damn wrong at that. Free Neutrons are stable for geologic eras of time, until they hit something.

2) Why do electrons and protons attract each other?

Simple Field Theory

3) Where does the 'charge' of an electron and a proton originate?

No idea. If you can explain the "Why, how and where" of fundamental forces, without revealing your ignorance of basic physics and centuries of observation and experimentation, then you MIGHT have something, but your other "Questions" suggest you are stupidly ignoring basic fact in many areas.

4) Explain the mechanism of the electron's repelling force against another electron.

Given Charge, this follows from simple field theory.

5) Explain why a magnetic field always has two poles.

Simple field theory

6) Explain why similar magnetic poles repel and opposite poles attract.

Simple field theory

7) Explain why magnetic fields affect the path of free moving electrons.

Simple Field theory

8) Explain why gravitational fields attract.

Simple field theory
