Well, there you are, then; it's all Einstein's fault;
this article relating to string theory proves it. :-)
Did you have an alternate proposal in mind that explains
all of the experimental results, then?
The only result I know of that does *not* confirm Einstein
is Miller's results in the 1930's, and I for one was
given to think that most of Miller's stuff was tainted
by various issues regarding temperature and gravity.
The Wikipedia article is in some dispute:
http://en.wikipedia.org/wiki/D._C._Miller
but suggests that the signal Miller actually detected was
far fainter than the apparatus was equipped to measure
(this according to Robert S. Shankland, among others),
though it also mentions that Miller's apparatus was not
sufficiently temperature-controlled.
Nor could anyone else reproduce his 0.08 fringe shift,
even today, during the 1920's.
A gradient of 0.01 C is more than enough to throw
things off, if one assumes a 10 meter long arm in the
interferometer. In the classical apparatus, granite is
used; this apparently has an expansion coefficient of
8.5 ppm/deg C.
http://www.supercivilcd.com/THERMAL.htm
If one assumes a 0.01 gradient and 10 m distance from
central mirror to far mirrors, source, or detectors, the
far arm of the gradient will have a length that differs
from the near arm by about 425 nm -- which is almost 3/4
a wavelength of the approx. 589 nm yellow sodium D lines.
Fortunately for the experimenters, if the source is hot
(or cold!) relative to the rest of the apparatus, that
arm isn't all that relevant to the actual measurement.
More sensitive experiments, among them Ives-Stilwell,
Pound-Rebka-Snyder, and for the most part Hafele-Keating
(who were also beset by statistical issues, though not
quite as badly as Miller) also confirm various aspects of
SR and GR.
The only other result might be experiments or
quasi-experiments referenced by our Uncle Al, and I
for one cannot explain the chirality issues there --
as I do not understand them. The theory confirmed
by these experiments (assuming it passes peer review)
however is upwardly-compatible with GR, unlike the various
Newtonian/Galilean variants usually used by most anti-SR
posters here.
Personally, I think string/brane theory is also of this
ilk; I'm not competent to critique it, though I am also of
the uninformed opinion that it needs far better predictive
power to be widely accepted.
Followups set.

That's a great news article. The reason that physicists haven't made
any real progress in physics since the 1980s is that they're all too
busy looking for a final theory of everything instead of trying to
axiomatize what is already known.

Everything but general relativity is firmly based in one group
structure or another, and general relativity is based in Riemannian
geometry which is fully axiomatized.
Are you proud of your stupidity, shooby?

You claim to have an undergraduate degree in Math, Shooby, but that
claim is hardly supported by much of what you say. How do you think
experimental predictions are made without generating them from axiomatic
systems? Ouija boards?
