Course 3 on Lorentz-Four-Contractions, Session 8, Part 2

If an object changes in the way it is detected, then the ways in which the parameters of the object appear are altered. If the appearance of the parameters of an object change not only due to the object's position, yet also because of the differences in "time" that it takes for light to reach the object as it changes position, then the object is also in another way changing in relative motion relative to light. Also, if an object changes direction, then its displacement relative to its initial axes of motion is altered, since that object would then be moving with a different range of motion. These two factors (speed relative to light and direction), are not the only two parameters that control the measurability of the spacial and time wise parameters of an object as it travels as a unit. If an object rolls, if it spins, if it oscillates, if its angular momentum changes, or if it vibrates are all factors that effect how the parameters of spaciality and time are changed while that object moves as a unit. Basically, if the appropriation and propagation of an object is one that changes how that object differentiates in space relative to light, then the manner in which the spacial and time parameters of that object appear to a bystander will change accordingly. The more that an object changes in such appropriations and propagations, the more that the spacial and time parameters will alter all around in their amplitudes according to one standing still. So, if an object maintains its appropriations and propagations relative to light, then its parameters will appear to not change according to a still measurer. This is not just an "appearance" of what you "think" you saw, this would be the way these parameters would literally change relative to your reference frame. So, to an minute degree, spacial and time related realities vary according to the perspective of different life forms. Yet, there is an overall material reality.
