Have you ever thought about what exactly could be responsible for our existence on this beautiful planet? In fact what exactly is the reason for the planets to exist?
Well, we all know that the matter visible to us in this universe has some fundamental building blocks or elementary particles.
We also know that for each elementary particle there is an antiparticle, the particle that has the same properties but opposite charge and that they follow the particle-antiparticle symmetry.
But there are yet another group of particles that violate this symmetry property ( also known as charge conjugation parity reversal symmetry(CP symmetry) )
This CP symmetry violation or the imbalance between matter and anti-matter could probably be accounted as the reason for the existence of the Universe.
But how could this imbalance occur?
The matter could still be classified into fermions which are further classified into Quarks which make up the protons and neutrons. Second is Leptons which consists of muon tau particles and neutrinos. Heavy particles to this neutrinos would have been present in the early Universe and subsequently decayed. These decays would have generated the observed matter anti-matter asymmetry.
