In one writers
group I read an unpublished story titled the Gods Of Time. It was a science
fiction story on the outside but really a philosophic examination of time. Time
is like God, an omnipresent force that gives shape to the whole universe and is
still total mystery.
It has been long
understood how gravity and time have an inverse relationship in Einstein's Theory
of General Relativity. Time slows down in gravitational fields. The equations
in General Relativity keep on working if you were traveling greater than the
speed of light if you have either negative time of negative gravity -but not both together.
In one theory
about the crush of matter inside a black hole came the question if time still existed?
Does infinite gravity obliterate time?
The theory had the interesting conjecture that in the singularity of the black
hole everything gets crushed down to the two elemental particles of the
universe gravity and time. Both particles would be at the very smallest size
dictated by the Plank Constant. The two particles are slightly asymmetrical and
if they were physical spaces we could see, one would have 12 dimensional sides
the other 14. This initial asymmetry is what divides matter from energy and
limits super-symmetry, there are subatomic particles that do not have symmetrical
partners.
In another
theory of dimensional gravity, similar to the idea of Time-Space, each graviton
is actually like a cell of space that expands or shrinks dependant on the gravitational
field it is in. That the real measure of distance in the universe is the number
cells, the size of each cell is effected by the gradational field it is in. What
we see as the vacuum of space is really a sea of free gravitons (each a
distinct and undividable space). The
speed of light in a vacuum is a photon passing a set number of gravitons per
second. When a photon is in a gravitational field that's more tightly packed
with gravitons then light bends and travels a greater distance.
Time on the
scale of human lives or how we perceive the passing of time is like a
multilevel thought experiment that has no answer because there are so many
contradictions involved. Science Fiction writers have long played with the paradoxes
of time travel. Traveling forward in time at a slower rate that the rest of the
world is possible but traveling backwards in time is still an unlikely maybe.
As another
writer I meet once said since the universe is expanding outward from the Big
Bang then time is really the location of how far out from the Big Bang we are
at any given moment. Time travel backwards is probably impossible because to
travel back in time would mean you would have to reverse the whole expansion of
the universe to get back to the location of the past. That thought doesn't eliminate
parallel universes but that a whole other idea.
Suddenly I'm
in the mood to write a little Sc-fi today.
