I send you a good paper that prove my transformation and my quantization of gravity is completely right and agreed completely also with Hafele-Keating. The Hafele–Keating experiment was a test of the theory of relativity. In October , Joseph C. Hafele, a physicist, and Richard E. Keating, an. I teach physics, and I love the Hafele-Keating experiment as a way to introduce relativity. Because the experiment has a lot of charisma, it’s cool to be able to.

These experiments, however, used subatomic particles, and were therefore less direct than the type of measurement with actual clocks as originally envisioned by Einstein.
Did Hafele and Keating Prove Einstein Wrong?
Scientific papers describing the Hafele-Keating experiment Hafele and Keating, “Around the world hagele clocks: This observer is the one referred to as an “inertial observer”. Tests of general relativity Tests of special relativity Albert Einstein in science. Nevertheless, the relative timekeeping behavior of terrestrial clocks can be evaluated by reference to hypothetical ahfele clocks of an underlying non-rotating inertial space 6.
This photo is from Time Magazine, October 18,where it appeared with “AP” written above the upper right yafele. If their motions were truly “relative”, then by the rules of SR both should arrive back at the starting point having experienced the same amount of time dilation in the same direction.
Around-the-World Atomic Clocks In OctoberHafele and Keating flew cesium beam atomic clocks around the world twice on regularly scheduled commercial airline flights, once to hafelw East and once to the West.
General relativity predicts an additional effect, in which an increase in gravitational potential due to altitude speeds the clocks up. Their predicted and measured time dilation effects were as follows: There is a web site and mailing list Time Nuts for people who do high-precision timing experiments for fun, and they have a museum with old photos and documentation.
This effect has been confirmed in many tests of general relativitysuch as the Pound—Rebka experiment and Gravity Probe A.
Translated by Perrett, W. Another common argument is to say that the path length has changed due to the rotation and this is why the speed of light is not measured to be C.

An online listing of errata for early editions of the textbook by Hartle says that the photo below of Luther and Dabney had been published with an erroneous caption describing them as Hafele and Keating.

Tests of special relativity. A reenactment of the original experiment by the National Physical Laboratory took place in on the 25th anniversary of the original experiment, using more precise atomic clocks during a flight from London to Washington, D. The plane was steadily observed using radar, and its position and velocity were measured every second. Naval Observatory undertook an experiment to test time dilation.

Hafele and Keating Experiment
All I currently know is where they were employed inthat Dr. Shown below is a drawing of our earth and sun moving through space. The time lost on the eastbound train was 20X higher than that lost on the north and southbound trains.
In the event that it is still copyrighted, it is reproduced here under the fair use exception to U.
This should also be true if he moves in a straight line from his stationary position at some absolute velocity. This observer is non-inertial since he is experiencing three different rotations with respect to the CMBr – diurnal, solar, and galactic.
General relativity’s prediction of the gravitational effect was confirmed in by Pound and Rebka.
If you plug in numbers for a 48 hour round trip flight at constant speed at the equator, you get ns and ns for the eastbound and westbound flights respectively. Kinematic Time Shift Calculation If the kinematic time dilation expression is expanded in a binomial expansionthen for small velocities it becomes This expression can be used to compute the time dilation in the Hafele-Keating experiment in which an atomic clock was taken aboard an aircraft and compared keatlng a ground-based closk.
Aircraft Time Dilation For an aircraft flying over the equator, its clocks will show a time shift relative to a fixed surface clock which can be approximately modeled by the expression. InChou et al. Taking a “proper time” at the earth’s center as if the master clock were there, the time measured by a clock on the surface would be larger and that for the airborne clock hafeele be approximately since to the level of the approximations used, the height of the aircraft does not significantly change the radius R.
From the actual flight paths of each trip, the theory predicted that the flying clocks, compared with reference clocks at the U. The height and velocity terms were predicted by Einstein in and — however the Sagnac term was unknown to Einstein when he wrote his papers on special relativity, so this effect was never anticipated by Einstein.
They carried with them four cesium beam atomic clocks. Leschiutta, Evidence for the earth gravitational shift by direct atomic-time-scale comparison, Il Nuovo Cimento B, 37B 2: In the setup on the left, the speed of light is measured as C. A group at the University of Maryland led by C.
Further, time dilation can be construed as simply an error in clock readings, as discussed here. Special containers protected the hafelle from external influences such as vibrations, magnetic fields, or temperature variations. The predicted values obtained by Hafele and Keating presumably were based upon detailed measurements of the speeds, etc. For travel eastward, v has a positive sign and the shift will be negative aging more slowly. The crew of each flight helped by supplying the navigational data needed for the comparison with theory.
This agrees with the relativistic predictions to a precision of about 1. Keating, an astronomer, took four cesium-beam atomic clocks aboard commercial airliners. Although inertial systems are highly hxfele, they have an objective physical relationship with the universe because they have no acceleration or rotation relative to the universe.
