The constancy in the observed speed of light came from Voigt who
discovered the Voigt transform being the earlier non-Galilean
transform that satisfy the null results of the MMX. <shrug>

This has a lot of implications. The most overlooked one is the flat-
space ego where every observer will always observe his space to be
flat even if his space appears and is observed to be hopelessly curved
by someone else. Thus, the curvature of space is a relative
comparison in concept. It all results in Voigt?s wisdom. <shrug>

The principle of equivalence was a Galilean discovery where the
Newtonian law of gravity becomes ever possible. So, this is not part
of core curriculum of relativity. It is merely a principle in
tradition. Without the principle of equivalence, Newtonian law of
gravity would not be possible. There is no big deal in the principle
of equivalence. However, when Einstein the nitwit, the plagiarist,
and the liar finally understood the simple Newtonian law of gravity,
the nitwit managed to reverse-engineer the Newtonian law of gravity
and since then had proclaimed the principle of equivalence as his own
basic organic discovery. What an insult to scholars of history if you

The most basic tensor is the Riemann curvature tensor which has
nothing to do with Riemann himself. Looking for how an object is able
to move through perceived curved space, Christoffel trivially derived
the geodesic equations. From the geodesic equations, Ricci saw and
defined an operator that results in null 4-velocity. Through double
application of this man-made operator, now called the covariant
derivative, a 4x4x4x4 (complete with 256 elements) matrix can be
fudged in which Ricci who named it the Riemann tensor. Arbitrarily
realizing 256 elements to a matrix is hopelessly useless. Ricci?s
student, Levi-Civita, condenses the 4-dimental Riemann tensor into a 2-
dimensional one which is now called the Ricci tensor with any
scientific justifications. The whole tensor business of things is an
idol of voodoo cult in practice. <shrug>
