Basic Physics says Movement is change in position, over time. “Time” however, does not truly exist. And space, as it turns out, is not actually physical. But, wait. Let’s take one thing at a time.
As we most often speak of it, Time is simply an artificial, human-made system of measurement. As we usually think of it, Time is merely an illusion of order, cast upon chaos – an illusion we cast by comparing all kinds of random and inconstant movements (which is, virtually all movement) against one or two of the very few things in the universe whose movements do seem completely predictable.
The only basis for counting "a second" is that we divide sunlight by 24, 60 and 60 again. How arbitrary! Atomic clocks may have replaced sundials, but neither atoms nor stars can explain why we use such things to measure all other movement. As Einstein(*) might have put it, our perception of time shifts considerably depending on which moving things we’re comparing.
In other words, there really is no such thing as time. There is only movement.
So let's think about movement itself, and how it takes place.
To be continued...
(*) That business of Einstein's with clocks on rockets is about ticking motion, not Time per se. The fact is, if you move really fast, ticking motion slows down. Atomic clocks on airplanes going 600 mph proved that it does. Now, I have no idea why that happens, but I know what does not happen. To say “time” slows down is just a manner of speaking. It’s all just relative motion – what Einstein called inertial frames – which is what (I'm told) Special Relativity is actually based on.
