So if time is the decay of energy into entropy, then that decay slows to zero at the speed of light. I get that.

Since speed is distance over time (v=d*t), distance -- space -- is an inverse function of time (d=v/t). But velocity is a function of time too, so v/t can be reduced to d=d, which is a unity, true in all cases.

What I'm getting at is that in simple Newtonian physics, you can't define space (distance) in terms of time unless you include velocity. For example, volume (which is also space) is measured in cubic inches. There's nothing in there that relates to time.

Does any of that make any sense?

I'm not sure where you got that, or even what it means, but it does bring to mind a real-life observation often used to demonstrate the realities of Einstein's theory of relativity.

And that is the detection of more atomic decay byproducts reaching the earth's surface from the sky than ought to, given their very short, known lifespans.

There are particles from deep space called "cosmic rays" (not to be confused with photons, the carriers of light) They (cosmic rays) are ionized atomic particles. Anyway, they continually rain down on earth, at varying rates, smashing into our atmosphere. When they do they collide with particles in the atmosphere, smash them apart, and/or they themselves are smashed apart?, and new short-lived particles are produced.

But based on the known lifespans of these various short-lived collision byproducts, most should never reach the detectors on earth's surface (they wouldn't exist long enough to make the complete trip).

What is happening is, due to their high rate of speed, the distance they have to travel (from their perspective, due to the effects of Einstein's relativity) is shortened, or 'contracted', such that they are able make it to earth in less time than ordinary calculations would predict they should.
