In the era of Postscientism the slogan "Relativity is false" sounds
like "The world is bad": both are truisms that nobody finds it
reasonable to react to. This allows clever Einsteinians to indulge in
the luxury of being honest from time to time. Here is John Norton's
version of "There is no gravitational time dilation":

"General relativity knits together space, time and gravity.
Confounding all common sense, how time passes in Einstein's universe
depends on what you are doing and where you are. Clocks run faster
when the pull of gravity is weaker, so if you live up a skyscraper you
age ever so slightly faster than you would if you lived on the ground
floor, where Earth's gravitational tug is stronger. "General
relativity completely changed our understanding of time," says Carlo
Rovelli, a theoretical physicist at the University of the
Mediterranean in Marseille, France.....It is still not clear who is
right, says John Norton, a philosopher based at the University of
Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his
instinct - and the consensus in physics - seems to be that space and
time exist on their own. The trouble with this idea, though, is that
it doesn't sit well with relativity, which describes space-time as a
malleable fabric whose geometry can be changed by the gravity of
stars, planets and matter."

Exceptionally clever Einsteinians such as John Norton and Banesh

even harder than the worst antirelativists ever do. Below Banesh
Hoffmann teaches that gravitational time dilation simply does not
exist:

Banesh Hoffmann: "In an accelerated sky laboratory, and therefore also
in the corresponding earth laboratory, the frequence of arrival of
light pulses is lower than the ticking rate of the upper clocks EVEN
THOUGH ALL THE CLOCKS GO AT THE SAME RATE. (...) As a result the
experimenter at the ceiling of the sky laboratory will see with his
own eyes that the floor clock is going at a slower rate than the
ceiling clock - EVEN THOUGH, AS I HAVE STRESSED, BOTH ARE GOING AT THE
SAME RATE. (...) THE GRAVITATIONAL RED SHIFT DOES NOT ARISE FROM
CHANGES IN THE INTRINSIC RATES OF CLOCKS. It arises from what befalls
light signals as they traverse space and time in the presence of
gravitation."

Chapter 14: "The equivalence principle has a striking consequence
concerning the behavior of clocks in a gravitational field. It implies
that higher clocks run faster than lower clocks. If you put a watch on
top of a tower, and then stand on the ground, you will see the watch
on the tower tick faster than an identical watch on your wrist. When
you take the watch down and compare it to the one on your wrist, it
will show more time elapsed."

Note that the two watches are placed at different gravitational
potentials (the alleged "gravitational time dilation" is a function of
the potential difference) but experience essentially the same
gravitational field. This means that, in Einsteiniana's wonderland,
identical clocks placed in identical physical surroundings run at
different rates, that is, there is an effect without cause.

Outside Einsteiniana's wonderland the explanation sounds quite
prosaic. In 1911 Divine Albert discovered and even published that the
speed of light varies with the gravitational potential, "V", in
accordance with the equation c'=c(1+V/c^2) given by Newton's emission
theory of light. This equation is equivalent to the equation c'=c+v
given again by Newton's emission theory of light and showing how the
speed of light varies with the speed of the light source, "v". That
is, by applying the equivalence principle, one converts c'=c(1+V/c^2),
valid in the presence of a gravitational field, into c'=c+v, valid in
the absence of a gravitational field, and vice versa. Needless to say,
the validity of the two equations is fatal for Divine Albert's Divine
Theory.

Later, in 1915, Divine Albert devised better camouflage but in 1911
the "gavitational time dilation", the effect without cause, was the
only protective fraud his panicky mind was able to produce.
