👉 A vacuum is a space where there are no particles or matter, and it can be thought of as an empty container for everything. In physics, vacuums are often used to describe states of matter that do not contain any form of energy or mass. Vacuums are also important in the study of quantum mechanics, which deals with the behavior of particles at very small scales.
Vacuum theory is a mathematical framework that describes the behavior of many-body systems, including atoms and molecules, by
