A couple of pertinent quotes

Waking up this morning and recalling a thought I had about this yesterday re that light slows down through different mediums, it’s slowed down by our atmosphere and slows down even more in the ocean, that is, different pressures affect it, I’ve decided to check to find out exactly what is being adjusted in GPS. It’s not Einstein’s ‘time dilation’, it’s adjustment for a physical phenomenon that there’s a difference in travelling from east to west from travelling west to east. Nothing to do with Einstein’s speed slowing down time. [My bold in the following extracts]
The GPS and the Constant Velocity of Light
Paul Marmet
“One must conclude that there exists no space-time distortion of any kind. It is no longer necessary to fascinate people with the magic of relativity. Unless we accept the absurd solution that the distance between N.Y. to S.F. is smaller than the distance between S.F. and N.Y., we have to accept that in a moving frame, the velocity of light is different in each direction. As mentioned above, this difference is even programmed in the GPS computer in order to get the correct Global Positioning. This proves that the experimental velocity of light with respect to a moving observer is c±v.”

“In the second part of the experiment, we send a beam of light around the Earth equator. We can anticipate that at each microsecond, the beam of light passes each line drawn on the ground, because they have been spaced by one microsecond-light (by definition). When we send the beam eastward, light goes across 133425 lines, and therefore take 133425 microseconds to go around the world, passing each line every microsecond. Also, when we send the beam westward, the beam of light also passes one line every micro-second, so that light takes 133425 to complete the trip around the world. Of course, the experiment is well done and light is traveling inside a vacuum pipe in which air has been completely pumped out.
However, following the Sagnac effect published in 1914 it has been shown experimentally that light takes a longer time to go around the world Eastward than Westward. The Sagnac effect is well known. It has been added in the Global Positioning System (GPS) to determine time and coordinates on Earth. The Sagnac effect is also used in optical gyroscopes. It is very well extablished.
How can the experiment above with light moving across each of the 133425 lines every microsecond be compatible with the observed Sagnac effect? How can the time taken, to go around the world be longer when going Eastward then Westward, since there are the same number of lines (133425)? Light takes exactly one microsecond to go between lines (by definition).
The answer to this problem will be given (and explained) here as soon as I have time to write it down, probably during the first part of 2000. Make a bookmark if you want to remember the Web address.

Of course, it is not a real paradox. It is physical reality. The answer is logical and uses conventional logic (I mean without the magic space-time distortion). ”
There you have it, nothing to do with Einstein’s relativity, which as I’ve shown came out of his mistaking perception through a medium, the mind, and thinking these changed objective reality..
And, my other point, that it’s not because Einstein’s relativity is oh so esoteric that it’s difficult to understand, but that it’s difficult to understand because it creates nonsensical ilogical scenarios claiming these are science facts: running down the corridor of the train will not slow down time for you while the person sitting still in the carriage goes faster and will reach the next station before you, nor is the actual distance from NY to SF longer in one direction than the other!

“Question – (2-B)
Can you give an example of an experiment giving results which are contrary to Einstein’s predictions?
A. – Yes. One of the most simple and remarkable experiment showing that Nature is not compatible with Einstein’s hypothesis is the one described by Sagnac in 1914. (Ref. Sagnac M. G., J. de Phys., 1914, 4, 177-195).
———————–
Question – (2-C)
Can you give a simple description of the Sagnac’s Experiment?
A. – Yes. Here is a simple description.
Let us assume that you have a source of light (a laser) at a certain location on Earth (e.g. your home). You project that beam of light directly toward a satellite in orbit around the Earth on which there is a reflecting mirror. After that first reflection, light reaches other mirrors in space so that it can finally complete a full turn around the Earth and reach again the same spot on Earth where light has been emitted.
Using that apparatus, you can measure the time it takes for light to make a complete turn around the Earth when light moves from West to East. Now, if you repeat the same experiment, with the same mirrors, (or even do it simultaneously), using light moving from East to West, you find that the time taken by light to move from East to West is shorter than the time taken for light to complete the revolution in the opposite direction. That difference of time is observed with the same apparatus, making simultaneous measurements, at the same location. One can show that this difference is due to the Classical Newtonian motion of Earth rotation. That difference of time for light taken between each direction depends directly on the velocity of the Earth moving around itself.
Einstein’s Theory claims that there is no possible way to detect the ABSOLUTE velocity of the Earth. The very use of the expression RELATIVITY comes from Einstein’s hypothesis that parameters, like VELOCITY, are relative so that any absolute motion (like absolute velocity) is meaningless. However, we see above, that the velocity of Earth is responsible for the change of time light takes to go around the Earth. From a fixed location on Earth, we can detect the Earth’s motion. Therefore, contrary to Einstein principle of relativity, the velocity of light is not relative to the observer. One must conclude that the Sagnac effect contradicts Einstein’s hypothesis of General Relativity.
Let us note that in practice, the Sagnac effect is observed quite easily. In order to observe that effect, you do not have to make a full circle around the Earth. If you make light rotate around a diameter of only one meter and many rotations, (in either directions) you will observe the same effect. The slight change of time interval to travel in either directions can be detected using interference patterns between the beams moving simultaneously in opposite directions. This method is very sensitive to detect a very small rate of rotation. Such an observation is very important in ships (or spaceships) and in airplanes. It is a kind of optical gyroscope (laser gyroscope) manufactured commercially in large number. This optical gyroscope detects the absolute velocity of the rotating Earth from any location on Earth, even if Einstein’s theory claims that light travels with respect to the observer.
There is also a Straight-Line-Component Sagnac effect. (see Einstein’s Theory of Relativity versus Classical Mechanics, chapter 9). This will not be developed here. The Sagnac effect has been discussed in many papers. Recently, A. Kelly (The Sagnac Effect and GPS Synchronization of Clock-Stations) presented a paper at the meeting of “Galileo Back in Italy”, Bologna May 1999. Ref. A. G. Kelly, HDS Energy Limited Celbridge, Co, Kildare, Ireland. The Sagnac effect on the GPS Clock synchronization is extremely important.
One can conclude that you can possess now your own instrument that measures the ABSOLUTE velocity of rotation of the Earth, which is in striking contradiction with Einstein’s Theory of Relativity, while most of the scientists still refuse to accept that this can actually work. This is the most striking proof that Einstein’s Theory of General Relativity is wrong.”
And more on GPS as Marmet deconstructs a paper by Ronald R. Hatch http://www.newtonphysics.on.ca/faq/relativity_gps_10.html
This is funny, doesn’t it remind you of the ‘gosh, we weren’t expecting to find this’ which crop up again and again in climate scientists making real measurements?
“R. Hatch expresses his surprise to discover that there is an increase of clock rate when the satellite is at apogee, while there is no change of clock rate when the other clock experiment moves from the pole to a larger Earth radius at the equator. Consequently, he claims that this requires a “new underlying relativistic phenomenon”. Using Newton’s laws, we show here that this is a natural phenomenon.” Paul Marmet (1932-2005)
