Variables of Nature

I had to laugh....the universal constant of gravity. And ....we aren't sure why these constants have the values they do...

So these constants are variables?

Maybe the post should have been titled Constants of Nature.

What is the reason that the Earth's orbit is exactly what it is? (Some things don't have a reason, it just turns out that way.) Possibly it's the same way with physical constants.

Because if it were slightly different, mankind wouldn't be here to ask the question "why".

Ah, yes, the Anthropic Principle. It suggests some kind of selection occurring (multi-universe theory), or Intelligent Design. Or we're just very lucky!

In Nature it's a CONSTANT when it's rate-of-change is ZERO...regardless of where or what.

Nature's physical 'constants' are not constants in the mathematical sense; they are constants insomuch as they have not been observed to change within the resolution of our instruments. They are only 'constant' as far as we know, and so it behooves us to find out for sure because, if they are not constant, a lot of physics will have to be rewritten. To merely assume they're all unchanging and so call them 'constants', believing that they are what they're called and not bothering to look deeper would be a huge disservice to Science.

Nature is subtle; we see this again and again. Some of our most profound discoveries were made because somebody went against the grain and questioned the prevailing wisdom, wisdom that preferred to gloss over tiny discrepencies in the data because it didn't fit the model.

They're not 'constants'; they are measured values or derived from measured values and as such are subject to the limitations of experimental measurement.

True constants exist only in mathematics, not in Nature.
