Confused about this antimatter stuff

A contribution to the matter anti-matter debate

Why should it be that the positron is the anti-electron, OK they have opposite charge and the positron does not like an electron and vica versa because when they meet they end up as gamma rays and their mass is annilated or rather cinverted into another energy form. Is this really conclusive proof to say that the positron is the anti matter of the electron?

When the positron is part of a larger mass i.e the proton, and the proton and electron meet then we have what is called electron capture and no burst of gamma rays and the proton changes to a neutron and instead of mass-annilation we have mass-unification.

Could it be that matter and anti-matter actually co-excist within the same particle (nucleus). If this could be true then the problem of where all the anti-matter hides, is solved.

If on the other hand if anti-matter is accumulated at an alternate point in space then surely huge fields would be excist between the matter and anti-matter.

My guess is that we will not know the answer for a long time and my statements above are as speculative as the statements that anti-matter should excist elsewhere.

You seem to have completely ignored HOW we often create positrons. Most of the centers that use positron sources create them via pair production, i.e. by creating electron-positron pairs via gamma rays (typically impinging on Be). We simply do not call something a "positron" simply because it has a positive charge!

QT is essentially a predictive theory that tells us what will, or has, happened; it makes no attempt to tell us how or why. Richard Morris summed up the current predicament in "Achilles in the Quantum Universe” with the following statement:
"They (physicists) feel a complete explanation of the subatomic world will not have been attained until it is known why particles have the charge, masses and other particular properties they are observed to possess"

There is no accepted (or Standard model) explanation of why things are the way they are. Take for example proton:proton collision which produces new quarks, they are said to be created out of the energy of the collision; but why should the energy of the collision form quarks? why not some other particle or an entirely new particle; the Standard model does not tell us.

does it exist any way to use antimatter as fuel . for the spaceships so they can fly very fast
