Anti-matter is a fundamental particle of regular matter with its electrical charge reversed..The common proton has an anti-matter counter-part called anti-proton and likewise the electron has an anti-matter counter-part called positron.Anti-matter particles are produced in high-speed collisions.
A solar flare collides with a high-energy proton it can form a type of nytrogen that has too many protons relative to the number of neutrons and the nucleus is made unstable causing a positron to be emitted to stabilise the situation.When the positrons hit an electron they produce energy.
After the Big Bang and the subsequent cooling,matter and anti-matter were in almost equal amounts but the matter was slightly higher and the residual amount of matter was left to form our universe.
