John Norton: "These efforts were long misled by an exaggeration of the
importance of one experiment, the Michelson-Morley experiment, even
though Einstein later had trouble recalling if he even knew of the
experiment prior to his 1905 paper. This one experiment, in isolation,
has little force. Its null result happened to be fully compatible with
Newton's own emission theory of light. Located in the context of late
19th century electrodynamics when ether-based, wave theories of light
predominated, however, it presented a serious problem that exercised
the greatest theoretician of the day."

John Norton: "In addition to his work as editor of the Einstein papers
in finding source material, Stachel assembled the many small clues
that reveal Einstein's serious consideration of an emission theory of
light; and he gave us the crucial insight that Einstein regarded the
Michelson-Morley experiment as evidence for the principle of
relativity, whereas later writers almost universally use it as support
for the light postulate of special relativity. Even today, this point
needs emphasis. The Michelson-Morley experiment is fully compatible
with an emission theory of light that CONTRADICTS THE LIGHT
POSTULATE."

There are two facts hinted at in the above texts which, in a world
different from Einsteiniana's schizophrenic world, would make the
respective theory (special relativity) extremely suspicious:

1. Originally (in 1887) the Michelson-Morley experiment was compatible
with the assumption that the speed of light varies with the speed of
the light source (as predicted by Newton's emission theory of light)
and INCOMPATIBLE WITH THE ASSUMPTION THAT THE SPEED OF LIGHT IS
INDEPENDENT OF THE SPEED OF THE LIGHT SOURCE (Einstein's 1905 light
postulate).

2. After a century of brainwashing no one wants to hear about the
original truth - people just know that the Michelson-Morley experiment
has gloriously confirmed Einstein's light postulate and that's it.

Note how artfully Norton, while being faithful to the true story,
still does not give any sign that something might be amiss.
