Vacuum isn't really vacuum according to quantum physics. How?

Question

Just messin' with you. I already know the answer.

Answer 1

Vacuum is the absence of matter, so there should be nothing in in.
However, in space, exist "quantum fluctuations" (we could call it vibrations of nothing) that "spontaneously" creates PAIRS of opposite particules (a particule and its anti-particule). The sum of the Energy created is Zero, so the principle of conservation of energy is not violated. The two particlues will attract each other and, after a short while, will hit each other and anihilate, again with a zero change in energy level.
From the creation to anihilation, the Vacuum is not empty, since in contains the two particules, so we should not call it "Vacuum"!!
Just a note:
After the creation of the particule pair, if it happens close to a strong gravity field (ie black hole), ONE of the particule COULD fall into that field and NOT anihilate with its brother. One particule will then "survive"... The law of conservation of matter is then broken, as a particule has been created from "nothing".
But that, is Quantum Theory...

Answer 2

My vaccum cleaner works fine. If it gives out I am getting a new Vacuum. Messin' with you tooo

Answer 3

there is no such thing as a true vacuum on nature
