      String Theory,........simply explained.
      Basically, "string theory" is a way of looking at the building blocks of matter and energy in a way that might very well clear up a dilemma that's been plaguing scientist for decades:  the argument that the two main branches of physics can't both be true!
      This isn't the physics we all suffered through in school. This is physics giving support and insight into life, into spirituality, into parallel planes of existence.  Take a look.  After all, physics is what defines the physical universe we live in.  Physics is about the objects within that universe, the forces that hold it together, and the secrets that make it tick.
      Physics is also about extremes.  At one end of the scale, the bizarre principles of "quantum mechanics" describe and predict the behavior of the very, very small:  atoms and their constituent parts.  At the other extreme, Einstein's two theories of relativity deal with the vastness of the universe itself, the speed of light, and the warping of space-time by massive bodies such as stars, galaxies, and black holes.
      Apart from their abstract beauty, both theories have proven themselves to be very powerful tools.  Quantum mechanics led to the development of the computer chip.  Relativity gave cosmologists the tools to explain all kinds of strange activity out there in the vastness of the universe.
      The problem, they say, is, if quantum physics is true, then relativity has to be false, and vice versa.  When you try to apply the rules that govern one realm to the rules that govern the other, they stop working.  Quantum mechanics suggests that at the subatomic level where matter and energy stop being separate entities, the universe is so chaotic and unpredictable that it's referred to as "quantum foam."  On the other hand, relativity only works in a perfectly smooth, highly predictable universe.
      For decades, physics have been seeking some way to unify these two powerful theories into a single Theory of Everything.  Now it looks like they might have found it--with string theory.
      According to this concept, the tiniest "things" in the universe are not the subatomic particles all of us have heard about--protons, neutrons, and electrons--nor even the more arcane particles nuclear physicists routinely handle--quarks, leptons, neutrinos... and so forth.  It appears that the most fundamental particles in the universe aren't really particles at all.  They're best described as loops of "string" that vibrate at specific frequencies.  These vibrational frequencies determine the "identity" of the string, and therefore what kind of particle it will be a part of:  a quark that's part of an atom that's part of a molecule of matter, or a particle that will ultimately become a photon of electromagnetic energy.  It all depends on the frequency of vibration.
      When viewed at that level, the "quantum foam" no longer looks so irredeemably chaotic.
      Well, that might please physicists, but what about the rest of us?  What does string theory mean to us?  You've probably already jumped on it:  String theory proposes that the shape and content of the entire universe is determined by vibrational frequencies in the heart of every single atom, every single particle.  This concept corroborates the proposition that ultimately there is no difference between matter and energy.  All is one--and all is a kind of music.  Sound familiar?  This concept has been understood by mystics and other spiritual individuals for centuries.
      But there's more.  At the minute level of string theory, a realm so tiny that it can be described only through highly complex mathematics, the universe isn't the four-dimensional construction we humans are used to perceiving and living in.  Humans function in a world of height, depth, width, and time.  That's all we know.  But that's not all there is--not by a long shot.  So far, physicists working with string theory are postulating that the strings exists in anywhere from 7 to 11 different dimensions simultaneously.  Eventually they'll find a 12th--some already say there are more.  At the other end of the cosmic scale, scientists now have evidence that some particles not only disobey Einstein's "cosmic speed limit"--the speed of light--but greatly exceed it.
      So what do these things mean to us on a human scale?  For one thing, they point out how much scientists still have to learn.  For another, we now know that there are other dimensions out there....  Taken to its logical conclusion, what this tells us is that the place where you are right now, as you read this book, exists in an infinite number of variations, all occurring at the same time.
