Here you go: Vacuum fluctuations. And: The Casimir effect: a force from nothing .
Or the whole Universe for that matter:
"There are something like ten million million million million million million million million million million million million million million (1 with eighty [five] zeroes after it) particles in the region of the universe that we can observe. Where did they all come from? The answer is that, in quantum theory, particles can be created out of energy in the form of particle/antiparticle pairs. But that just raises the question of where the energy came from. The answer is that the total energy of the universe is exactly zero. The matter in the universe is made out of positive energy. However, the matter is all attracting itself by gravity. Two pieces of matter that are close to each other have less energy than the same two pieces a long way apart, because you have to expend energy to separate them against the gravitational force that is pulling them together. Thus, in a sense, the gravitational field has negative energy. In the case of a universe that is approximately uniform in space, one can show that this negative gravitational energy exactly cancels the positive energy represented by the matter. So the total energy of the universe is zero."-- Steven Hawking, 1988, "1988. A Brief History of Time", p. 129
It is a belief system. Valid obseravtions, but to infer to totality from a limited set -- that's religion.
