Beliefs on matter

Discovery of the quark

We now know that neither the atoms nor the protons and neutrons within them are indivisible. So the question is: What are the truly elementary particles, the basic building blocks from which everything is made? answer

Using the wave/particle duality, everything in the universe, including light and gravity, can be described in terms of particles.

[[Forces particles]]

Force-carrying particles can be grouped into four categories:

1. [[Gravitational force]]

2. [[Electromagnetic force]]

3. [[Weak nuclear force]]

4. [[Strong nuclear force]]
