Article - Zero Point Field

It isn't just "finally" being studied; this is predicted by the theories surrounding Quantum Mechanics...more specifically string theory. You see, we know matter is composed of ever smaller units...but there has to be a "smallest" unit somewhere, before matter breaks down into pure energy. A molecule is broken into atoms, atoms into subatomic particles (electrons, protons, and neutrons), sub atomic particle into quarks, quarks into alpha and beta particles, and so on and so on; Until you reach the "string" with is a small packet of vibrating matter that is simplest form of matter composed not of more matter, but only of energy. The frequency of vibration (resonance freq.) defines what it becomes when it is paired with other strings. A single string will flux in and out of it's matter state and energy state, until stabilized by other strings. This of course leads to many other theories, but I believe you get the idea. If you want to know more, I suggest reading Steven Hawking's "Universe in a Nutshell," which deals more with hard science than the not-so-objective article on "Zero point fields."
