👉 Visitors, often referred to as light particles, are fundamental components of quantum mechanics and particle physics. These entities are not bound by classical physics; instead, they exhibit wave-particle duality, meaning they can behave both as particles and as waves. Visitors, or more specifically, photons, are massless particles of light that travel at the speed of light in a vacuum. They are crucial in various phenomena, from the photoelectric effect to the operation of lasers and fiber optics. At the quantum level, visitors interact with matter in unique ways, such as absorbing or emitting energy in discrete packets called quanta. Their behavior is described by quantum field theory, which provides a framework for understanding their interactions with other particles and fields. In essence, visitors are the building blocks of light and play a pivotal role in the fabric of the universe at the smallest scales.
