I think there is something rather than nothing because the state of "nothing" is UNSTABLE. According to the Heisenberg Uncertainty Principle (H.U.P.) of Quantum Physics,” nothing” does not stay “nothing” for long. A true nothing means no energy, no space and no time. Nothing might be thought of as a sphere of zero radius with nothing around it. Once a quantum event occurs (and it will according to H.U.P.) and the radius of this sphere expands slightly, the pressure ratio of the pressure inside of the sphere to the nothing "outside" of the sphere (zero pressure) is infinite or near infinite. Remember that a number divided by zero is infinity. This infinite pressure ratio causes a rapid expansion as in a Big Bang explosion - a bit like putting a balloon in a vacuum chamber. Since less pressure exists outside of the balloon, it expands rapidly and bursts. Google and download "The Origin of the Universe - Case Closed". It's easy to understand and will explain in greater detail. It also explains how the mass and gravitational energy in the universe is created from nothing without violating the Law of Conservation of Energy. It explains the origin of the universe from nothing.
I like the analogy of the balloon.
"Nothing" is also discussed in a nice video I posted earlier:-http://nutsandreasons.blogspot.com/2012/01/debunking-kalam-cosmological-argument.html at about 21minutes; but the whole video is worth a watch.
