Detailed explanation-1: -The quantum vacuum is the state of absolute nothingness that exists between particles at the quantum level. It is a realm of pure emptiness, with no particles or energy present. Yet, this void is far from empty.

Detailed explanation-2: -A vacuum is a space devoid of matter. The word is derived from the Latin adjective vacuus for “vacant” or “void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure.

Detailed explanation-3: -The phrase “Nothing exists in a vacuum” is correct literally and figuratively. Very true. The moment that there is “something” there, it ceases to be a vacuum. In a pure vacuum of a defined space, nothing exists.

Detailed explanation-4: -By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it’s nearly empty. Related: What would happen if you shot a gun in space? That emptiness results in an extremely low pressure.

Detailed explanation-5: -In quantum field theory, the quantum vacuum state (also called the quantum vacuum or vacuum state) is the quantum state with the lowest possible energy. Generally, it contains no physical particles.
