Particle physics deals with the study of the subatomic particles and their interactions. All the masses of the universes galaxies, planets, everything is made of the subatomic particles. Till today, there are many fundamental particles discovered like electrons, quarks, leptons etc. Through the study of behavior of these particles and their interactions, we can know about the universe, we can understand what principle the universe really follows. More than 95% of the mass of the universe is dark matter and dark energy. We have not known much about them. There are thousands of scientists working globally and billions of dollars is invested for understanding about the 95% mass of the universe.
