1. Why is there more matter than antimatter in the Universe? Or: Why is there matter at all? (If there were the same amount of matter and antimatter, and it came into contact, it would quickly get destroyed.
2. If antimatter is so abundant, how come we've never come in contact with it or have been able to observe it?

Is dark matter related to antimatter in any way?
Dark matter and antimatter are two separate entities. Dark matter is a mysterious form of matter that does not interact with light, while antimatter is composed of antiparticles that have the opposite charge of normal particles. There is currently no known direct relationship between dark matter and antimatter.
What is a positrin?
A positron is the antimatter counterpart of an electron, with a charge exactly opposite to the electron. Like other antimatter particles if it comes into contact with its matter counterpart the two will mutually annihilate.
What is the an end product of matter-antimatter annihilation?
The end product of matter-antimatter annihilation is energy in the form of gamma rays (high-energy photons) and sometimes other elementary particles like neutrinos. This process releases a tremendous amount of energy due to the complete conversion of the mass of both particles into energy, following Einstein's famous equation E=mc^2.
What is matter and antimatter changed into if they touch?
When matter and antimatter touch, they annihilate each other, converting their mass into energy in the form of photons (gamma rays). This process is governed by Einstein's famous equation, E=mc^2, where energy is equal to mass times the speed of light squared.
