Quantum fields

Quantum fields are fundamental entities that permeate the universe, serving as the underlying fabric from which particles—like electrons and photons—arise. Imagine every point in space as having a field that can oscillate or fluctuate; these fluctuations manifest as particles when observed. Instead of particles being tiny points, modern physics views them as excitations within these fields. Quantum fields unify particles and forces, providing a framework where particles are interconnected and dynamically interact across space and time. This approach helps explain phenomena at the smallest scales, revealing a universe where what we see as particles are actually ripples in an invisible, all-encompassing quantum landscape.
