kaksmet said:I believe the thought goes like this: Matter and antimatter are created in equal amounts, therefore the world should not exist since the two should annihilate into energy once again. However, some effect in the early universe is thought to change this by breaking the CP (Charge Parity) symmetry. There is however no such effect observed that are strong enough to account for the huge surplus of matter. But if we for the moment accept that something caused this (for example a CP violation effect in the strong force), this would explain why the electron, and the up and down quarks make up our universe.
Matter and anti-matter are two forms of particles that have opposite charges. Matter particles have a positive charge, while anti-matter particles have a negative charge. They also have opposite spin directions.
Particles group together in matter because of the strong nuclear force, which is one of the four fundamental forces of nature. This force is responsible for binding quarks together to form protons and neutrons, and for binding protons and neutrons together to form the nucleus of an atom.
The existence of anti-matter in the universe is still a mystery to scientists. It is believed that equal amounts of matter and anti-matter were created during the Big Bang, but somehow matter became more prevalent. The presence of anti-matter can also lead to matter-anti-matter annihilation, which produces high-energy photons.
Yes, matter and anti-matter particles can interact with each other. When a matter particle and an anti-matter particle meet, they annihilate each other and produce energy in the form of high-energy photons.
Scientists study matter and anti-matter through particle accelerators, such as the Large Hadron Collider (LHC), which can create and study these particles at extremely high energies. They also use detectors to observe the particles and their interactions, and mathematical models to understand their behavior and properties.
