No, protons and neutrons were not made up by "idiots" or physicists. Protons, neutrons, and electrons are fundamental particles that make up atoms and contribute to the structure of matter. They were not invented or created by scientists; rather, their existence and properties were discovered through scientific observations and experiments.
The study of subatomic particles and their properties is a complex field of physics called particle physics or quantum mechanics. Physicists have dedicated years of research and experimentation to understand the fundamental building blocks of the universe and the forces that govern them. Their work has led to the development of the Standard Model of particle physics, which describes the properties and interactions of particles like protons, neutrons, and electrons.
It's important to recognize and appreciate the scientific process that has allowed us to understand the nature of matter and the universe. Scientists continually refine their understanding based on new evidence and experiments, and their discoveries have had a profound impact on our understanding of the world we live in.
