If the observer suddenly starts moving towards the light source, the
frequency of light increases (Doppler effect). This has a SIMPLE
IMPLICATION: the wavecrests are now bumping more frequently into the
observer, that is, THE SPEED OF LIGHT RELATIVE TO THE OBSERVER HAS
INCREASED. "But this is fatal for Divine Albert's Divine Theory" - say
to themselves Einsteiniana's teachers and replace the SIMPLE
IMPLICATION with an IDIOTIC ONE:

John Norton: "Here's a light wave and an observer. If the observer
were to hurry towards the source of the light, the observer would now
pass wavecrests more frequently than the resting observer. That would
mean that moving observer would find the frequency of the light to
have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE
BETWEEN CRESTS - TO HAVE DECREASED)."

Einsteiniana's teachers know quite well that the wavelength is
determined by the light source and cannot depend on the movements of
the observer. So Stephen Hawking has offered better camouflage: when
the light source, not the observer, starts moving, the wavelength
shift looks less idiotic:

Stephen Hawking, "A Brief History of Time", Chapter 3:
"In the 1920s, when astronomers began to look at the spectra of stars
in other galaxies, they found something most peculiar: there were the
same characteristic sets of missing colors as for stars in our own
galaxy, but they were all shifted by the same relative amount toward
the red end of the spectrum. To understand the implications of this,
we must first understand the Doppler effect. As we have seen, visible
light consists of fluctuations, or waves, in the electromagnetic
field. The wavelength (or distance from one wave crest to the next) of
light is extremely small, ranging from four to seven ten-millionths of
a meter. The different wavelengths of light are what the human eye
sees as different colors, with the longest wavelengths appearing at
the red end of the spectrum and the shortest wavelengths at the blue
end. Now imagine a source of light at a constant distance from us,
such as a star, emitting waves of light at a constant wavelength.
Obviously the wavelength of the waves we receive will be the same as
the wavelength at which they are emitted (the gravitational field of
the galaxy will not be large enough to have a significant effect).
Suppose now that the source starts moving toward us. When the source
emits the next wave crest it will be nearer to us, so the distance
between wave crests will be smaller than when the star was stationary.
This means that the wavelength of the waves we receive is shorter than
when the star was stationary. Correspondingly, if the source is moving
away from us, the wavelength of the waves we receive will be longer.
In the case of light, therefore, means that stars moving away from us
will have their spectra shifted toward the red end of the spectrum
(red-shifted) and those moving toward us will have their spectra blue-
shifted."
