👉 Existence fluid, also known as quantum vacuum or zero-point fluid, is a theoretical concept in physics that describes the lowest possible energy state of a quantum mechanical system. Unlike classical fluids, which are composed of particles like molecules or atoms moving freely, existence fluid is thought to be a sea of virtual particles that constantly pop in and out of existence due to quantum fluctuations. These fluctuations are a fundamental aspect of quantum mechanics, arising from the Heisenberg uncertainty principle, which dictates that certain pairs of physical properties, like position and momentum, cannot both be precisely measured at the same time. Existence fluid is not a tangible substance but rather a mathematical construct that helps explain phenomena such as the Casimir effect and the Lamb shift. It represents the inherent "emptiness" of space at the quantum level, where energy is never truly zero but exists in a dynamic, ever-changing state.
