Philosophical Basis As Observer-Dependent Idealism
is not about the physics of relativity. It is about its philosophical
basis, specifically its dependence on observational frame of reference.
The most obvious absurdity inherent in this philosophy is the denial of
objectivity, i.e., that there is no "real world" independent of all
possible different perspectives (including from relativistic
velocities) The most absurd case is the example called "length
contraction." The claim is that the length of an object, or the
distance between objects (say stars) depends on the speed and direction
of the "frame of reference" observing the object or distance. In a
world dependent only on observation (Einstein's world of "special
relativity), *there is no objective physical world independent of how
it is observed!*
you visit the relativity section of any "mainstream" science forum, you
will find zero tolerance for the above philosophical criticism. All
such critics are "banned" once they point out the above
absurdity. I know; ... I've been banned from all of them, and from
citing any source critical of relativity in Wikipedia. (LCcritic is my
user name as a Wikipedia editor. See last section of my "talk page"
there for details of this ubiquitous intolerance of any serious
criticism of relativity among all physics editors there.)
other part of relativity (besides "special relativity") is general
relativity. Einstein correctly pointed out that a (blind) "observer"
can not distinguish between the force of accelleration and the force of
gravity, so he concluded that there is no such thing as "the force of
gravity." Rather, he accepted Minkowski's theory that mass "curves
space" (or "spacetime") and that the latter "guides" masses (and light)
in their curved paths... the orbits of planets, for instance. But there
is absolutely no ontology explaining *what "spacetime" IS* anywhere in
the general theory of relativity. It remains relativity's version of
"The Emporer's New Clothes!" To be a credentialled physicist in
relativity, you must accept (if not admire) the "fabric of spacetime"
as a malleable entity which functions as above. You are not
allowed to ask what it IS!
See my piece on the Higgs Field (above) for an explanation of gravity that now (since 2012) has actual evidence to support it.
