Particle/antiparticle are only different in electric charge but annihilate into energy?

A neutron has no charge. Its anti particle, the antineutron also has no charge. The particles are different and will annihilate each other if brought into contact. So it is not true that "charge is only difference".

It just is. Quantum mechanics is great at describing the atomic world and predicting outcomes to experiments, but it can't give us a conceptual model of why so many things are the way they are. Lots of it doesn't seem to make intuitive sense and disagrees with what classical mechanics would predict, but as my physics professor put it "our job is to explain, not complain." I'm no expert but annihilation may have something to do with the strong force, as it about a million times stronger than the electromagnetic force between protons and electrons and easily trumps electromagnetism.

Ego quite has to dissolve of its own accord. Ego is selfishness and concern, concern that "the different" will harm the guy, earnings benefit over him, deprive the guy of his desires. as long because of the fact the needs exist, the ego would desire to proceed to take care of its perfect to have those issues. whilst the day comes that the Self starts to work out the greater advantageous fee of a unified humanity, that all and sundry living beings are manifestations of God, then the internal maximum desires dry up and blow away like final 12 months's leaves. In technology, whilst we are youthful we see all gadgets as separate and sturdy. Then we hit upon that they are atoms, with whirling electrons, and that maximum area is truthfully empty, so we ask your self in regards to the obstacles we had felt to be so real. The human physique is consistently taking in its atmosphere, water permeates the exterior, sound waves enter the ears, radiation is absorbed, oxygen comes into the lungs, pollutants are eradicated from the physique: it extremely is a persevering with flux particularly than a sturdy merchandise status on my own. some day it dawns on the Soul that we are area of a universe.

Charge is not the only difference. All intrinsic quantum numbers are inverted: parity, helicity, strangeness, charm, color, lepton number, you name it.
