Time dilation has apparently been ‘proved’ experimentally by running two flights with equal velocity in opposite directions, one east wards and another west wards (Hafele-Keating experiment).
It was apparently noted that, compared to the readings of the atomic clock at the US Naval Observatory, the atomic clock in the east bound flight recorded less time (59 nanoseconds less) and that in the west bound flight recorded more time (273 nanoseconds more). This was apparently because, from the reference frame of an observer at the Earth’s centre (God only knows why we have to bring this fellow into the scene!), the clock in the east bound flight was moving at the highest velocity (=earth’s rotational velocity+ flight velocity), the clock in the west bound flight was moving at the lowest velocity (earths rotational velocity – flight velocity) while the clock at the observatory was moving at the same velocity as the earth’s rotational velocity. We know that according to special relativity, the faster a clock moves, the slower the clock ticks. So the time readings from the three sets of clocks appeared to support the predictions of special relativity.
(We have mentioned at the beginning that both flights ran at equal velocity but in the opposite directions. So one may be wondering why the velocity of the east bound flight is considered more than the west bound flight while predicting the time dilation. The reason is that the flight velocities are taken from the reference frame of the centre of earth observer. Because Earth rotates in the east ward direction, this rotational velocity gets added to the east bound flight making its relative velocity more than the west bound flight which runs opposite to the direction of the earth’s spin. Little tricky to understand but not stupid unlike the relativity theory itself!)
Why Twin Flight Experiment doesn’t prove Relativity
“Relative to the atomic time scale of the U.S. Naval Observatory, the flying clocks lost 59+/-10 nanoseconds during the eastward trip and gained 273+/-7 nanosecond during the westward trip—” (http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/airtim.html)
Even if we believe in the clock readings ‘observed’ by the experimenters, that would still not prove special relativity despite the swearing by the physicists. Imagine that the stationary clock at the observatory ticked 100sec while the clock in the east bound flight ticked 90sec and the clock in the west bound flight ticked 110sec (just to keep the numbers simple). Though these readings might appear to be consistent with the predictions of special relativity from the perspective of the centre of earth observer, the same is not the case from the perspective other observers. For example from the perspective of the observer on the earth, both flights were moving at equal velocity and hence both must have experienced time dilation by the same factor and should have read the same time. But this was not the case.
And, from the perspective of an observer in the east bound flight, it was actually the west bound flight which was travelling at a very high velocity. So according to him, the west bound flight should have experienced the maximum time dilation and ticked the slowest if SR were to be true. Also the observatory clock should have experienced some amount of time dilation and hence ticked slower than his ‘stationary’ clock. Similarly the clock readings would go against the predictions of SR when viewed from the perspective of the west bound flight.
What it implies? The readings of the clocks (believing that the data was not ‘massaged’ by the ‘phychicists’ having got mesmerised by the stupid religion!) appear to obey the formula of SR only when looked from the reference frame of the centre of earth observer. (Same is the case with GPS clocks)
The only conclusion a sane mind can draw from the twin flight experiment is that the functioning of atomic clocks get affected by motion and gravity. It also suggest that motion is not relative, in other words there seems to be an absolute reference frame. But why the atomic clocks get affected as ‘exactly’ predicted by the mathematics of SR? Surely it is not because of time dilation effect. If it was Time that dilates, then all processes should get slowed down by the same factor in a given scenario. And that should include the physical process underlying the pendulum clock also. Unfortunately for the relativists, this is not the case.
But why the atomic clocks got affected as ‘exactly’ predicted by the mathematics of GR and SR? Well, they actually didn’t: https://debunkingrelativity.com/twin-flight-experiment/#comment-3383
‘Twin flight experiment disproves the delusion of ‘Time dilation’ and constant SOL
We can straight away discard the idea of constant speed of light using the same twin flight experiment. Imagine that a beam of light with velocity ‘C’ is shone towards the west. According to the law of constant speed of light, all the observers (the flights and the earth) must agree upon the speed of light as C. For the west bound flight in the above illustration to measure the light beam’s velocity as ‘C’, it will have to experience time dilation. Similarly for the east bound flight to measure the same light beam’s velocity as ‘C’ it will have to experience time contraction. But this is not what the clock readings from the twin flight experiment suggested.
