Fred,

Every action is it's own clock, so yes, all the actions balance out.

There are two sides to everything. The opposite of the infinite is the absolute. Which is also "only" a property of space. The unmoving void of absolute zero. The vacuum through which light moves at C. The frame with the fastest clock and longest ruler.

Zero to infinity, like the number line.

The issue of the Planck length does give me pause, as it would require an even more precise definition of boundaries, or the error bar is as long as it and it fades back into the blur.

I have tended to stay fairly close to ground level, as there has been little appeal in climbing this Tower of Babel. Though having grown up in the country, this hasn't been a difficult choice.

Cheers on the New Year.
