چکیده:
One of the first results of quantum field theory is that the vacuum is a carrier of energy (infinite). This result is consistent with empirical tests and, to some extent, with other fundamental theories of physics, such as the general theory of relativity. In this article, by examining the ontological dimensions of the concept of vacuum in philosophy and physics, we will first conclude that what is called vacuum in physics does not mean absolute nothingness and, fundamentally, absolute nothingness neither in classical physics nor in modern physics can be a source of energy or measurable. Furthermore, we will show that this result does not mean the complete dismissal of philosophical discussions regarding the concept of vacuum in physical theories, and without addressing these discussions, a clear and distinct interpretation of these theories cannot be provided.

He believed that if everything in this cosmos were limited, there must exist an infinite space and void, and therefore, unlike what some interpreters imagine (Crombie, 1961: 36), his view was different from the atomists' view, who considered atoms to be the essence of the cosmos and the space between them to be the void (Capek, 1976: 22).
He did not believe that space and place existed as an essential entity separate from bodies, and he considered this to be a consequence of the non-existence of the void.
3. Ontology of the Vacuum in Quantum Field Theory and General Relativity From the previous points, it can be concluded that nearly two millennia of philosophers and physicists have considered the vacuum, in the sense of an absolute nothingness, to be a predicate without a subject and deemed its existence impossible.
Einstein progressed in the physics of space and its properties, such as the gravitational field, to the point where he considered making the concept of ether impossible in the theory of relativity.
Einstein did not consider geometric space without a gravitational field to have physical reality, and this was his view regarding the standard cosmological model.
