What is the universe actually made of? For centuries, scientists believed everything around us was built from tiny particles of matter. Atoms, electrons, protons, and neutrons seemed to be the fundamental ingredients of reality. But modern physics has revealed something far stranger.According to Quantum Field Theory, the universe is not fundamentally made of tiny solid particles. Instead, it is filled with invisible quantum fields that exist everywhere in space. What we call particles are actually tiny excitations or disturbances within these fields.An electron is an excitation of the…
