The physical world we live in is made of all matter which occupies space. Not only matter (Electrons, Protons and Neutrons), but many other miscellaneous things do exist in the spooky world of quantum physics/chemistry. It’s not just matter that matters but matter is again made of Sub-atomic particles, which are of two types, namely Composite and elementary particles. These two topics are studied in both Particle physics and Nuclear physics.
