Question

what you mean by zero point energy

Answer 1

heya, here's ur answer.....

 In quantum field theory, the vacuum state is the quantum state with the lowest possible energy; it contains no physical particles, and is the energy of the ground state.

This is also called the zero point energy; the energy of a system at a temperature of zero.

hope this helps u ☺

Answer 2

Zero-point energy (ZPE) or ground state energy is the lowest possible energy that a quantum mechanical system may have. ... All these fields have zero-point energy.
