Reflections on relativity?....Rejections of relativity!

Welcome. This is a reasoned response to the relativity section at, a site promoted as the on-line and authoritative reference for all seeking explanations of mainstream relativity and its math support.

Mathpages is in fact our favorite comedy site on the Web, a truly modern fantasy, full of contradictions. Presented as mathematical support for relativity, it actually brings the errors into focus, a comedia errata. It is puzzling why it is cited to support any type of science, as the site is saturated with logical and mathematical errors, an unintended satire of modern thought. If grounded firmly in logic and mathematics, no one need be troubled by the intimidation of special relativity flak launched therein.

Does lack of response to the mathpages outrages signal descent into agnosticism and to nihilism beyond? God help us all.

All comments will be posted that are civil, relevant and coherent.

1.8 Another Symmetry

1.8  Another Symmetry
We saw in previous sections that Maxwell’s equations are invariant under Lorentz transformations, as well as translations and spatial rotations.
- We also saw that this was of no consequence.  Nature has a absolute reference system. reciprocity we have vij = ?vji
- A key relation for future analysis.

If acceleration were relative (like position and velocity), we would expect the cyclic symmetry vij + vjk + vki = 0, which is a linear function of all three components. Indeed, this is the Galilean composition formula. However, since acceleration is absolute, it's to be expected that the actual relation is non-linear in each of the three components.
- In sum, position and velocity are relative; acceleration is absolute. 
So saieth mathpages.

... the relativistic composition law for velocities accounts for the increasing inertia of an accelerating object. This leads to the view that inertia itself is, in some sense, a consequence of the non-linearity of velocity compositions.

1. Velocity compositions are linear.
2. Inertia is the effect of aether.

These are the Lorentz transformations for velocity v in the x direction.  The y and z coordinates are unaffected, so we have y' = y and z' = z.  From this it follows that the quantity t^2 - x^2 - y^2 - z^2 is invariant under a general Lorentz transformation, so we have arrived at the full Minkowski spacetime metric.
-Further analysis of Lorentz transforms is of interest to mathematicians, but has no application to physics.
