neutral atoms/matters has no net charge, but electrostatic induction between charges within atoms will end up a net attraction force, which is proportional to total charges within matters.

the fact that two separate magnets in free space will end up attract each other no matter pole directions is due to similar em induction.

from Fg=G x m1m2/r^2 and Fe=Ke x q1q2/r^2, we see the similarity.

all we need to prove is m1=q1=total charges within, m1=q2=total charges within.

as i said earlier in my theory, 3 building blocks make up atoms.

proton carries 900 positive charges, electron carries 1 negative charge, enertron carries tiny negative charge, but it has more charge to volume ratio than electron.

a proton can never be observed by itself, proton is deep hidden within a dense enertron ball. atom is like earth, proton is the core, enertron is the dirt, electron is giant beach ball.

electron can never get inside of atom radius, that's why atoms are not compressible, no discharge within atom.

proton attracts -899 energtron and 1 electron to become neutral charged atom.

we can not detect enertron because it is too small and attracted by proton more strongly than electron.

when proton beams impact, in fact is proton/enertron balls impact, enertron balls explode, produce all kinds of em phenomena.

without charges, there is no force, there is no mass. cus you cannot measure mass without using force.

1 atomic mass equals to 1800 total charges, no matter the sign of the charge, that's why proton weight 1800 times electron weight but only carries 1 positive charge, the rest 899 positive charge is used up to balance -899 enertron ball.

a hydrogen atom is made of +900 charged proton surrounded by -899 charged enertron ball, add 1 electron on the outer sphere.

the atom has 2 force fields, positive field fp=ke x 900/r^2, negative field fe=ke x -900/r^2.

those positive and negative fields between atoms/matters interact/induction becomes bounding/gravitation.

now let's prove mass=total charge

1 neutron contains 1 proton and 1 electron, total charge 1800. equal to hydrogen atom total charge/mass.

all we need is an induction constant C* to convert Fg=G x m1m2/r^2 into Fe=Ke x q1q2/r^2.

C* x m=q, where m is mass, q is its equivalent induction charge carried.
