Norton, "Einstein's Investigations of Galilean Covariant
Electrodynamics prior to 1905":

Einstein: "I certainly knew that the principle of the constancy of the
velocity of light is something quite independent of the relativity
postulate [see chapter 7 in his "Relativity" where he derives the
former from the latter]; and I considered what would be more probable,
the principle of the constancy of c, as was demanded by Maxwell's
equations, or the constancy of c, exclusively for an observer sitting
at the light source. I decided in favor of the first, since I was
convinced that each light [ray] should be defined by frequency and
intensity alone, quite independently of whether it comes from a moving
or a resting light source."

Needless to say, this argument of Einstein's against the emmission
theory of light is absurd but John Norton gives a more serious reason
why Einstein abandoned this theory:

"The principle of relativity, if implemented in Galilean kinematics,
dictated that the modified theory must embody an emission theory of
light. We know that Einstein entertained such a theory.....Einstein
leveled objections against all theories of this type. Some were
technical complications. The most fundamental, however, was that these
EMISSION THEORIES ADMITTED NO FIELD THEORY.

However at the end of his life Einstein said:

"I consider it quite possible that PHYSICS CANNOT BE BASED ON THE
FIELD CONCEPT, i.e., on continuous structures. In that case, nothing
remains of my entire castle in the air, gravitation theory included,
[and of] the rest of modern physics."

So one can "consider it quite possible" that modern physics died long
time ago.

I consider it quite possible that you lost your brain long time ago.

Thank God, a Pancho posting. Just as I thought sci.physics.relativity
had been totally spammed out by It's A Miracle.

Shucks! It's generous of you to say he had one once.

Would it be, because, you do believe in a spam!?
