The convergence of the physics and ancient Indian wisdom happens to be a very profound subject of study across the world. The goal is not only to find the parallels between these two subjects but to cultivate a unified system of thought which inspires human intellect to take a giant leap into the vast expanse of Reality.
During early 1900, when Dirac solved the negative energy problem of relativistic version of quantum mechanics, he introduced the concept of quantum vacuum, which is also known as physical vacuum. In his formalism, the physical vacuum was proposed to be an infinite sea of negative energy states. These states are occupied by a particle and its corresponding anti-particle. In his original version, they are electron and positron pairs. The quantum vacuum is therefore not the vacuum of nothingness.
