then what is
E=MC2....isnt this only relevant to the observer and has no place in the "wider scheme of things"
Mass is local, (especially the mass in question in the equation) and is different depending upon the object in question.
C, on the other hand, is something a little bit different.
Special Relativity states that the speed of light is invariant in all refrence frames.... that is to say, if a photon is moving from the earth to
mars, and you are traveling at about half the speed of light in the same direction....
You would still, according to special relativity, see the photon as moving at the speed of light relative, to you, even thought you are moving (with
respect to earth and mars) exactly half as fast as it is, and therefore should see it as moving (relative to you) at also, half the speed of light.
This has to do with the theory of relativity, and how it treats time as a Fundamental dimension (like the other three, height, width, and length.) and
the specific geometric coordinate system transformation, that treats c as an absolute, and time and space (interval and distance) as "Mutable"
Thus, the theory of relativity posits that TIME is a fundamental aspect of reality, as opposed to the Mental Abstraction "scalar" measurement that
In essence, Special Relativity is ultimately self defeating, as it relies on certain things to be true, in order to be a working theory, while
simultaneously it is incapable of being TRUE, while those very things that it relies on to be true, are also true.
Basically, Einstein got his theory wrong.... but he got it wrong in such a way as that to the casual, and occasional professional observer... it
This is sort of like the "Wandering Planet" theory that was supposed to explain the apparent retrograde motion of mars as seen from earth...
Eventually, this theory had to be scrapped when it was realized that the earth was not the center of the solar system, and in fact revolved around the
sun, thus completely explaining the apparent retrograde motion of mars.
Relativity acts similarly in this regard, as the foundational assumptions of relativity are JUST wrong enough to appear correct, if one does not
understand the nature of their incorrect assumptions.
Namely... that time is not a foundational variable of the universe....
So, to answer your question... Yes... but it's rather complicated.
