Hafele and Keating compared time intervals of atomic clocks in aeroplanes which on their trips eastwards and westwards around the earth to that of an atomic clock on earth.
Considering the Hafele–Keating experiment in a frame of reference at rest with respect to the center of the earth, a clock aboard the plane moving eastward, in the direction of the Earth's rotation, had a greater velocity (resulting in a relative time loss) than one that remained on the ground, while a clock aboard the plane moving westward, against the Earth's rotation, had a lower velocity than one on the ground.
Question Einstein Logic Test Item 8
What can be concluded by results of Hafele-Keating experiment?
Choice of answers of Einstein Logic Test
A) The results are conform to the existence of time dilatation according to Einsteins Theory of Special Relativity
B) The results are conform to the second postulate of Special Relativity: Constancy of light speed to all inertial frames.
C) The results are exclusively conform to classical and neoclassical physics (VTOE).
