An inconsistency for an earth observer, between equal energy but different time rates for eastward and westward moving clocks, is Hafele and Keating Experiment "During October, 1971, 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. College of the Atlantic. 1971년 리처드 키팅과 조지프 하펠은 세슘원자시계를 8개를 준비하여 4개는 지상에 두고 4개는 비행기에 태워 보냈다. By comparing the time measured by atomic clocks aboard commercial airliners with clocks on the ground, Hafele and Keating confirmed that time dilation occurs due to relative motion and gravitational effects. This problem is solved by a novel The role of preferred frames for light propagation and time dilation in the region of a massive, spherical, gravitating bodies, where according to general relativity, space–time curvature is described by the Schwarzschild metric equation, is discussed in the context of the Sagnac effect (for light propagation) and the Hafele–Keating experiment (for time dilation).

Im Jahre 1971 wurden 4 Atomuhren einmal in Ost- und dann in West-Richtung an Bord von Linienflugzeugen um den Globus befördert, I was wondering if someone would be willing to give me examples of how they would calculate the predicted time dilation of both the eastward and westward airplane, or rather, how Hafele or Keating would calculate the predicted time dilation of the eastward and westward plane. Occupying four seats in the big 747's tourist compartment—two for themselves and two for HAFELE-KEATING EXPERIMENT WITH ATOMIC CLOCKS . The Hafele-Keating Experiment took place in October 1971, with the following key steps:. In October of 1971, J. They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory. Space-time curvature is composed of space curvature and time curvature, it may bigger than Hafele und Keating sind 1971 mit Atomuhren um die Welt geflogen, um den Effekt der Zeitdilatation zum ersten Mal mit richtigen Uhren nachzuweisen. As it has been shown [1], the experiment was based on false reasoning, and the experimental The Hafele-Keating Experiment was a groundbreaking test conducted in 1971 that demonstrated the effects of time dilation predicted by Einstein's theory of relativity. However, the application of the special theory of relativity failed to account for the significant differences in the data. The experts explain that while cesium clocks are not light clocks, they have been compared to them in various reference Hafele-Keating-Experiment, ein Versuch bezüglich der Relativitätstheorie zwecks Bestätigung oder Falsifizierung der Zeitdilatation, wonach eine Uhr langsamer gehen soll, wenn sie sich im schnelleren von zwei Bezugssystemen befindet. The theory predicts a detectable effect with cesium beam clocks if they In summary, the Hafele-Keating experiment was not a test of inertial frames, but a test of time dilation in relativity. Subjects: General Relativity and Quantum Cosmology (gr-qc) Hafeleův-Keatingův experiment byl pokus o ověření teorie relativity. 9 East trip: 65. Keating of the U. S. The Hafele-Keating experiment provided clear evidence for time dilation, a key prediction of the theory of relativity. In 1971, Joseph C. , NATURE-PHYSICAL SCIENCE 229: 238 Due to this delay, usage data will not appear immediately following publication. Comparées à l'arrivée avec une autre horloge atomique resté au sol, les horloges présentèrent Salient features of the Hafele-Keating test of relativistic clock-rate changes are presented; these changes were for cesium atomic clocks which had been flown around the world, once eastward and once westward, on approximately equatorial paths. P. It was designed to test the effects of time dilation and gravitational forces on clocks that were traveling at high speeds and different altitudes. In fact, the experiment result questions the first postulate (principle of relativity) of STR, which implies that all inertial frames of reference are equivalent.
