Space free of matter is not truly empty. A vacuum is not a void. In quantum electrodynamics, the Heisenberg uncertainty principle implies that, even in the ground state, there is irreducible activity, with the continual creation and annihilation of virtual particles.
Thus, a vacuum contains a dynamic "sea" of quantum fluctuations. Several celebrated phenomena, including the Lamb shift, spontaneous emission and the Casimir effect, provide compelling experimental evidence for their existence.
