The above explanations do not sound EASY?!

A fixed distance? an inalterable constant? They are ideal models that are more of an idea than a fact.


A meter is whatever we consentually agree upon at a particular time and place on Earth.

Given that:
Gravity probably has distinctly different strengths depending upon what dimension you are in.
Light will move through certain forms of matter at different speeds yet the maximum speed through sapce time will always be the same.

!!!!!!!!!!!!!!!!!
Space can do what ever it damn well pleases whether it is to expand, condense or bend.!!!!!!!!!!!!!!!!

Whatever measurement you make on our scale of the universe, it will always be relative.

Some parts of the universe are already moving at faster than the speed of light relative to our planet.

Things are pretty fixed in the same locality but the rules get flexsible depending upon distance speed and space time dimensions.

Its not that we are bending the rules but rather that the rules bend depending upon what is acting upon them at a particular relative speed, scale, mass, form of energy and dimension it resides... as well as all the changes that are happening in the cosmos be they known or unknown to us.

I suppose it is easy to say a meter is always the same unless you are comparing it to another meter in motion elsewhere where it is always different.
