GRAVITY, SPEED OF LIGHT AND THE SALVATION OF RELATIVITY |
Does the speed of light vary with the gravitational potential and, if
yes, can it become greater than c=299792km/s? Clever relativists would
answer yes and then again yes but then would save Einstein's theory by
declaring that, for an INERTIAL observer, the speed of light is always
c=299792km/s (not so clever relativists would save Einstein's theory
by answering anything and then again anything). The solution to the
following problem could clarify the situation:
A light source on the surface of a huge celestial body, where the
gravitational field is enormous, sends light towards a very distant
INERTIAL observer (where the field is zero). What speed of light c'
will the observer measure?
In 1911 Einstein offered the equation c'=c(1+V/c^2), where V is the
gravitational potential difference between the light source and the
observer. Clearly, Einstein's 1911 equation is a direct solution to
the problem but this solution is extremely dangerous for Einstein's
theory because the observer is INERTIAL. The alternative solution is
c'=c but that is even more dangerous. So in the end Einsteinians would
only be able to save Einstein's theory if they manage to avoid this
problem forever. At least they should never choose explicitly between
c'=c(1+V/c^2) and c'=c.

Test of Einstein's theory of general relativity
On 10 October 2003, the Cassini science team announced the results of
a test of Einstein's theory of general relativity, using radio signals
from the Cassini probe. The researchers observed a frequency shift in
the radio waves to and from the spacecraft, as those signals traveled
close to the Sun. According to the theory of general relativity, a
massive object like the Sun causes space-time to curve, and a beam of
radio waves (or light) that passes by the Sun has to travel further
because of the curvature. The extra distance that the radio waves
travel from Cassini past the Sun to the Earth delays their arrival;
the amount of the delay provides a sensitive test of the predictions
of Einstein's theory. Although deviations from general relativity are
expected in some cosmological models, none were found in this
experiment. Past tests were in agreement with the theoretical
predictions with an accuracy of one part in one thousand. The Cassini
experiment improved this to about 20 parts in a million, with the data
still supporting Einstein's theory.
