The common language says that we live in the third dimensional world and when w die we"ll move into the fourth dimension. Many times the December 2012 dating is used to imply a transition from a third to a fourth dimensional world. But are there but three or four, or could there be many more extra dimensions?
Since Einstein forced physicists to think of time as a fourth dimension there have been speculations about a fifth and even higher dimensions. Way before Einstein though there were the Kabbalah teachings of eleven or twelve such dimensions. An age of enlightenment is opening up on many fronts.
There has been a revolution in our thinking about extra dimensions. Few area even aware of such concepts, let alone any discussions. A new understanding of the feasibility of localizing four dimensional gauge theories in higher dimensional spacetimes has led to a variety of phenomenologically viable models, and even to the possibility of localizing gravity. Say what?
Let"s back this up a bit. The three dimensions are length, width, and heigth. When you add time, we now have four. But, when we"re speaking esoterially or spiritually, the fourth dimension is used more as an "other world:, and "etheral realm" that we can only speculate exists. It"s the world that savants, gifted men like Ghandi, and Jesus spoke.
Now, while time is very different from the familiar spatial dimensions, Lorentz and Einstein showed at the beginning of the 20th century that space and time are intrinsically related. The idea of additional spatial dimensions comes from what the Kabbalah crowd spoke of that we relate to string theory- which is just that a theory!
But, the veil of ignorance is coming off.
The reason we do not feel these additional spatial dimensions in our everyday life (if they exist) is because they are very different from the three dimensions we are familiar. It turns out that it is possible that our world is PINNED to a 3-dimensional sheet. To illustrate this, imagine an ant crawling on a sheet of paper in your hand. For the ant, the "universe" is pretty much two-dimensional, as it cannot leave the surface of the paper. It only knows North from South and East from West, but up and down don"t make any sense as long as it has to stay on the sheet of paper. In pretty much the same way, we could be restrained to a three-dimensional world, which is in fact a part of a more complicated multi-dimensional universe!
But, and this is one of the points and purposes of this web site, I beleive we are on the cusp, leading up to 2012, of breaking out of our currnet consciousness and into an awareness of the universe that will totally change our view(s) of life and therefore us.
