About this Subtopic

Temporarily (that is: For now until Later) this is just about setting up points that shall help to eventually formulate Astronomical Standards that are fit for common sense.

In a sense norms are always relative to a locale. Although we measure speed as an Absolute thing, the numbers we use are relative to our scale. Sometimes though they are absolute. 1 Year is 1 Rotation - done. 1 Rotation has 365 subrotations - a day.
For our convenience we have settled to divide a day into 2x12 segments - so called hours - that on a subscale of five is segmented into 60 so called minutes.

As we so come to measure time relative to the rotation of our locale we can regard certain differences to other ones, thus scientists have come to realize the potential significance of the hydrogen atom, the most Universal component in our physical existence. If there were a locale where one "hydrogen spin" is different to ours, then we had to talk of an actual time-difference ... Eventually. Some people say that science has more often been wrong than right - and what finally matters is the individual significance of each individual component.
These use Meters, those use Miles. All however use parsecs, but those again are different for every solar system individually. Thus, while there is a locale, that is what we know and 'own'. These are a basis to our Understanding - and while that exists, some of us may want to look further.

But that isn't all! Sometimes we produce Chaos as we measure and go on, which means that eventually there will come an order into it. How to find your way through the sky for instance? North-Star? Large and Small Bear? But to me the most obvious constellation yet remains to be Orion. Why stick to a wagon to find the north if I got no clue where to look for it? Well, eventually its simple - but in relation to the bigger picture it to me feels like trying to learn an Alphabet starting in the middle.
