What is the difference between an anti-proton and an electron?
How do they create anti-matter?

[Lonesome in Massachussets]

An anti-proton has the same mass as a proton, which is much greater than the mass of the electron. An electron and an anti-proton cannot interact to anihilate one another.

Good questions. I think it helps to keep in mind that these are just names given to particles and may not accurately represent the full extent of their physical characteristics.

Mass and the antimatter particles’s lifetime here. The difference is mainly mass though.
