SPACE-TIME
CONTINUUM
"As three-dimensional beings, we perceive
time only as a result of memory. We remember what was as a
variable interval from what is now. If we had zero memory, we
could not detect time - we would exist only for the moment. The
result of this is our apparent perception of time as a linear
line, always going forward. This is similar to primitive peoples
perceiving the Earth as flat. It could be infinite - the horizon
always kept bringing something new no matter how far they
traveled; or, it could be finite, in which case there was the
risk of falling off the edge.
The terms three-dimensional,
fourth-dimensional, and any other references to dimension in
regards to "beings" means only that the being can directly
perceive that
many dimensions. A three-dimensional being cannot
directly see the fourth dimension; the three-dimensional being
can only infer its existence. The fourth dimensional being can
directly perceive the fourth dimension. However, almost all
objects exist in all dimensions. Also, a dimension does not need
to be detected to exist. If we had no memory of the interval we
label as "time," our progressive existence in space/time would
still occur.
In its simplest form, a
curve, extended infinitely, becomes a circle (or, better yet, a
sphere). A sphere, when looked at micro scopically without
precision, would appear as a flat surface, just like primitive
people perceived the Earth. Only when enough of the Earth was
explored and technology was developed adequately could the true
form of Earth be determined. The same holds true for
three-dimensional beings trying to grasp the dimension of time.
We need to perceive/detect the macroscopic view in order to
determine form.
For the initial
attempts at perceiving something outside of our normal senses,
precision is not necessary. Einstein stated that space is finite
but time is infinite. The problem here is that infinite is not
calculable. We need to make it finite in order to progress. We
can do this for time.
For practical purposes,
time for any given object (such as a particle, an atom, a
molecule, a person, a planet, a star, a galaxy, a universe)
begins from that object's coming into existence and ends when
that object ceases to exist in that form. (Never mind the fact
that energy cannot be destroyed, only changed in form. We
are
dealing here in non-precision in order to get a finite value for
the initial attempts.) If the object's existence in time was
exactly linear, the object's existence would appear to a
fourth-dimensional being as a perfect sphere. However, to the
third-dimensional being, time seems like a straight line going
on forever. Both are correct from their individual points of
reference. A fourth-dimensional being could traverse this time
continuum simply by going from point A to point B, because that
being can perceive that dimension. The third-dimensional being
cannot.
Objects whose X,
Y, Z axis change (objects in motion) do not exist in time
linearly. You cannot change your position in the X, Y, and Z
axis without also changing your position in T in a nonlinear
fashion. A perceived fixed object (a stone lying on the
ground, a building, a mountain) does move as a consequence of
movements through space (Earth orbital, geologic, etc.)
and the force moving the object through time. So, even
perceived fixed objects move within the space/time
continuum - there are no true stationary objects.
Could a stasis
field cause an object to cease moving in space/time? Nature
abhors lack of motion just as much as it abhors a vacuum. A
perfect stasis field might be difficult to achieve. Maybe an
object might have its travel through space/time retarded to a
more or less degree, depending on the success of generating a
stasis field around the object.
Because existence
in time is nonlinear, assuming a perfect sphere as the form of
an object's existence in the fourth dimension is not correct.
More likely, the object's existence might be as an ever changing
stream. The whole of space/time could then be considered as
bundles of streams intertwining, bundling, dispersing out,
merging in. Or, the form may be a cloud with voids and dense
areas. Ultimately, space-time could have a recognizable form,
once perceived on a large scale.
However, for
nonprecision calculation purposes, the best analogy of an
object's existence in space/time is as a ball of yarn gradually
increasing in size. There is a beginning (the object's coming
into existence). The object continues to exist nonlinearly - the
windings of the yarn gradually making the ball larger. The point
here is at any given moment in the object's existence, time is
finite. Always in motion and always with infinite possibilities.
Yet, nonetheless finite when we do not require precision. And,
even though the possibilities for that object are infinite, the
object seldom strays from a certain mean - thus the ball of yarn
analogy. For example, consider repetitive motions (routines,
cycles). These motions repeat, but never precisely - just like
adjacent strands in the ball of yarn."
