What is the evidence for time dilation?
1, Clocks on orbiting satellites move slower 2, Atomic clocks on planes move slower 3, Michelson-Morley experiment 4, Muon particles decay more slowly while falling Each of the evidence has been explained below: Clocks on GPS satellites Global Positioning System (GPS) satellites are used to help pinpoint a location on Earth. The location finding method requires that a satellite transmit a time signal to a GPS receiver which can then determine its distance from the satellite by measuring the time that the signal took to reach the receiver. Atomic Clocks on Aeroplanes Atomic clocks are the most accurate of clocks known to man. It has been said that if an atomic clock, such as a caesium clock, were to be flown on an aeroplane, those clocks should move at a different speed relative to those on Earth Michelson-Morley experiment The Michelson-Morley (M-M) experiment was performed in 1887 to determine the existence of ‘luminiferous ether/aether’, which was the medium believed to allow the propagation of light waves. The experiment consisted of comparing the speed of light along different directions by observing interference patterns in coherent beams Muon decay Muons are subatomic particles generated when cosmic rays strike the upper levels of our atmosphere. They have a half life of about 2.2 microseconds (µs) meaning that every 2.2 µs, their population will reduce by half. Conclusion: Evaluating experimental data is difficult because it requires accepting that the published results of the experimenters are correct and that their assumptions were valid.
