If you define b as being a fixed distance from a, then obviously. If you define b as being the other end of a stick, relativistic contraction will apply if the stick moves relative to an observer.

Physics is very logical and explicable if you use the same words as everyone else, and appreciate dimensional analysis.Since you use words arbitrarily, and have no respect for dimensional analysis, you are wasting your time here.

Say we had a meter stick that is made of platinum with density 21.08 gm/cc. Say from our reference we see distance contraction due to relativity, so the meter sticks appears to be 90 cm . Does the stick's platinum density increase by 10% to 23.18, since the volume of the meter stick has contracted by 10%? Or is only the energy, reflecting off the stick, changing due to relativity? An analogy is refraction, where we can see a stick appear to bend, when placed in a glass of water. The matter of the stick does not bend, but rather only the reflected light appears to bend. If we see energy output from a quasar that is highly red shifted, nobody says the mass went down or up whether it comes of goes from us. It always goes up; relativistic mass. If we modified the twin paradox, where younger twin was in motion, but he was moving away, so he appears red shifted therefore space-time appears to expand, he will still age slower, even though energy shows red shift and this implies space-time expansion, that should make him older???

If you define b as being a fixed distance from a, then obviously. added by me - (it is an axiom)

Anything measured between these two constant points other than distance is a rate of something, ( a speed)?

The distance of space between A and B can not be destroyed, bent , stretched, curved?

PLEASE read about dimensional analysis, if only to keep your driving licence!QuoteThe distance of space between A and B can not be destroyed, bent , stretched, curved?Once you have appreciated dimensional analysis you might begin to understand relativity. https://en.wikipedia.org/wiki/Length_contraction is an excellent summary of this part.

I have not even mentioned objects, why do you keep bringing objects into the question I am asking?

Maybe you have had enough of being a moderator and explaining to people like me?

only the ones where I think there might be a chance you could understand,

if these said facts can be discoursed, and questioned, then they are not definite facts

I am sorry but science offers very little evidence of truths to people like me,

Between set points A and B is a constant and an invariant, fact.

Thebox...A distance is a distance, is a distance, no matter if it is a yard, meter, mile, or light year... A speed is a speed, is a speed, no matter what type of distance it is measured against.And... a speed can only be measured in relation to the amount of 'time' that it takes a particular 'speed' to cover a given 'distance'...I think the phenomenon that you 'may' be attempting to illuminate is this:It happens that the constancy of the speed of light in a vacuum, takes exactly 1 second, as measured by a 'stationary clock', to travel 1 meter...Under the remit of GR, and also proven in experiment, a stationary clock placed 1 meter higher in elevation to another stationary clock situated at ground level, will run a fraction of a second 'faster'! (see NIST ground level relativity experiments 2010)This is given as further proof of GR, and of GR's remit of a gravitational field 'slowing' the rate that a clock will run at...Therefore, by definition, a light source that radiates away from Earth by 1 meter 'distance' at the 'speed' of light, will take this, 'observed by experiment', small fraction of a second (as measured by the clock at ground level) less 'time' to cover the next elevated distance of a meter, and so on...This rendering the measuring of space by the means of light years, in terms of the speed of light in relation to the distance of a meter, perhaps just a tad complicated, maybe, ...and is a contributing factor in GR's description of the curvature of space.However, if we were to measure the distance of an elevation from Earth, of 2 meters, via a 2 meter meter stick with a mark exactly in the middle, and we were then to measure this distance via the speed of light per second, this being a second as measured by the clock on the ground, we would then find that our 1st meter would be of the normal meter length, but from the halfway mark, our second meter would measure up a fraction shorter than the entirety of our 2 meter meter stick.... Without including the fact of the fraction of a second that the clock elevated at 1 meter is running faster than the ground level clock at, within the equation, the second meter of distance will appear to be shorter...Is this along the lines of what you are talking about box?
