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 predicted a time difference of ns on an eastward flight around the world for which the flight time was They flew twice around kating world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory. A more complex and precise experiment of this kind was performed by a research group at the University of Maryland between September and January Shown below is a drawing of our earth and sun moving ieating space.

Invan Baak measured the gravitational time dilation of a weekend at the top of Mt. Inexperimenters from the U.

Hafele and Keating Experiment

All articles with unsourced statements Articles with unsourced statements from June This observer is the one referred to as an “inertial observer”. But for our figure 3B the path length does not change for our laboratory observer since the loop is stationary in his frame.

Hafele, a physicist, and Richard E. They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory. For the path on the right, something more interesting happens. Michelson—Morley experiment Kennedy—Thorndike experiment Moessbauer rotor experiments Resonator experiments de Sitter double star experiment Hammar experiment Measurements of neutrino speed.


Relative to the atomic time scale of the U. I don’t know the copyright status of the bottom one. 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.

The Hafele—Keating experiment was a test of the theory of relativity. Only a preliminary analysis of the scientific results is presented, and the focus is mainly on the performance of the clocks.

Hafele-Keating Experiment

Their predicted and measured time dilation effects were as follows: Consider the diagram in Fig. Special containers protected the clocks from external influences such as vibrations, magnetic fields, or temperature variations. Article in Google Books. The observable effects of absolute accelerations and of absolute velocities must be ascribed to interaction of bodies and physical systems with some absolute inertial system.

The results were verified to a higher degree of accuracy. Louiswas preparing notes for a physics lecture when he did a back-of-the-envelope calculation showing that an atomic clock aboard a commercial airliner should have sufficient precision to detect the predicted relativistic effects.

In addition to the scientific papers published in Science[3] [4] there were several accounts published in the popular press and other publications, [9] [12] including one with a photo heading this article showing a cabin attendant checking her wristwatch while standing behind the instruments.

Lemmon for the television show Genius by Stephen Hawking. Views Read Edit View history. Hafele and Keating Experiment “During October,four cesium atomic beam clocks were flown on regularly scheduled commercial jet flights around the world twice, once eastward and once westward, to test Einstein’s theory of relativity with macroscopic clocks.

All I currently know is where they were employed inthat Dr. Measurements hafelr which the only effect was gravitational have been conducted by Iijima et al.


Hafele–Keating experiment

This paper describes the Gravity Probe A experiment, in which a suborbital probe measured gravitational time dilation on an atomic clock to about 0. Keatingan astronomer, took four cesium-beam atomic clocks aboard commercial airliners.

The predicted value of ns for hfaele westward flight of 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. One-way speed of light Test theories of special relativity Standard-Model Extension.

Did Hafele and Keating Prove Einstein Wrong?

In the course of digging up the photos, I ended up compiling some other links and information. In the event that it is copyrighted, I am reproducing it here under the fair use exception to Haefle. Any biographical information about Hafele or Keating. The time difference was observable during the flight, before later analysis.

Some have cited Max van Laue as discussing the effect after the proposal of Michelson inbefore Einstein was even known in terms of special relativity in From Popular Mechanics, Januaryp. Kinematic Time Shift Calculation If the kinematic time dilation expression is expanded in a binomial expansionthen for small velocities it becomes This hafelw 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 to a ground-based closk.
