Time Travel

Time is a relative measure.  The second is 1/24/60/60, or so, of a revolution of the earth on its axis.  A day is 1/365, or so, of a revolution of the earth around the sun.  These have been further refined to where they are measures, accurate to the nth degree.  The sun, however, is not fixed in the universe and probably moves on a path of some sort as do all of the celestial bodies that make up the universe.  All of them/us are moving.

This motion is relative, i.e., faster or slower depending on the velocity of the mover in relation to the others.  An astronaut in space ages at a slower rate than one remaining on Earth.  The key to this statement is the word slower.  At no time ever does the movement stop; the time vector never goes negative.  It gets shorter or longer relative to another but never less than zero.

There are theories that indicate the relative motion/position of bodies and predict that travel at greater than the speed of light is possible.  Yet none of these register time with a negative vector.

When one looks at it qualitatively, one can see that since time is the measure of motion, in order to reverse time the entire universe would have to stop and then go in reverse; an absurd proposition.

There is, however, the spiritual world, of which we are also a part.  In that world there is no mass, therefore no gravity.  There is no energy, therefore no impulsion.  There is only the existence of the present and the past; there can be no existence of the future since it hasn't occurred yet.  And what will occur cannot be predicted with any assurance.

The past exists with or without our accessing it. It can be accessed by us via our memory, which can be stimulated by any number of external factors.  It may come to us as a revelation, a premonition, a bit of deja- vue; in other words it may just boil up and pop into our conscious.  Could this be a memory cued by a roving spirit in the spiritual world?  So one can say that there is time travel, although not in the conventional, physical sense of it.
