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.

Hafele and Keating Experiment

In this experiment, both gravitational time dilation and kinematic time dilation are significant – and are in fact of comparable magnitude. For small changes in gravitational field associated with changes in altitude above the earth, the approximate time dilation expression is.

The predicted value of ns for the westward flight of These results provide an unambiguous empirical resolution of the famous clock “paradox” with macroscopic clocks. From the actual flight paths of each trip, the theory predicted that the flying clocks, compared with reference clocks at the U.

Any biographical information gafele Hafele or Keating. The time difference was measured by direct clock comparison at the ground before and after the flight, as well as during the flight by laser pulses of 0.

Special, General, and Cosmological, Springer-Verlag,p. It gives an experimental answer to the twin paradox. Those signals were sent to the plane, reflected, and again received at the ground station.


I have retouched the photo, but that retouching is not copyrightable under U. InChou et al. I’ve obtained and scanned copies some of these and posted them hafdle. In his original paper on special relativity[6] Einstein suggested a possible test of the theory: They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory.

Because the Hafele—Keating experiment has been reproduced by increasingly accurate methods, there has been a consensus among physicists since at least the s that the relativistic predictions of gravitational and kinematic effects on time have been conclusively verified. If he sends clocks around the loop, their rate of hxfele will be slower in either direction.

Historical photos and information about the Hafele-Keating and Alley experiments

Views Read Edit View history. If this was a snapshot taken by the crew or another passenger, then it is now in the public domain due to its publication without notice before A Question of Time”. Hafele, a physicist, and Richard E.

Only a preliminary analysis of the scientific results is presented, and the focus is mainly on the performance of the clocks. The clock on the train travelling east counted slower compared to the stationary clock at To. In following a circular path, the HK experiment becomes a Sagnac effect experiment where it is clocks that are moving rather than beams of light.


Hafele-Keating Experiment

When reunited, the three sets of clocks were found to disagree with one another, and their differences were consistent with the keatinb of special and general relativity. The time difference expression should be valid, but in comparing the aircraft clock to the surface clock, we should find that it has fallen behind, so we can model that time difference by.

The results were verified to a higher degree of accuracy.

Keating’s approximate date of death in Invan Baak measured the gravitational time dilation of a weekend at the top of Mt. General relativity predicts an additional effect, in which an increase in gravitational potential due to altitude speeds the clocks up.

Relative to the atomic time scale hhafele the U. The plane was steadily observed using radar, and its position and velocity were measured every second.

In Hafele and Keating’s experiment, they flew cesium clocks around the world in opposite directions near the equator, and then measured how much time they have gained or lost when they return to the hsfele point as compared to a stationary cesium clock to which they were originally synchronized.
