This is not
very dissimilar to the theory of relativity of Einstein. Isaac Newton thought that time
was like an arrow. Once fired, it could never
return. Einstein, however, thought that time was more like a river, which meandered and
speeded up or slowed down near galaxies and stars.
The new wrinkle on all of this is that scientists today
believe that the river of time may have whirlpools, or have forks.
Einstein has been looking for the "Theory of
Everything".
For over half a century scientist have been puzzled over
why the basic forces of the cosmos - gravity, electromagnetism, and the strong and weak
nuclear forces - require markedly different mathematical descriptions.
But, if we see these forces as vibrations in a higher
dimensional space, their field equations fit together like pieces of jigsaw puzzle,
perfectly snug, in an elegant, astonishingly simple form.
