Xinhang Shen questions Einstein's special theory of relativity on the same ground as I do in the Physics Essays article Challenge to the special theory of relativity (2016). Xinhang is CEO and President of NAC Geographic Products and expert on remote sensing and GIS Geographic Information System.
A key argument is that clocks tick at the same rate independent of inertial motion and so it is possible to set up a system of universal time, without any effects of time dilation of special relativity. In Xinhang’s words, Einstein’s special theory of relativity SR is fake physics. All users of GPS should be happy that SR there serves no real role; with the jungle of time dilation of SR, GPS could never work. GIS if anything connects to standards of time and space and so even an ardent believer in SR may learn something listening to Xinhang. As scientist it is surely more productive to listen than to close eyes and ears and stubbornly stick to text book physics which may be fake.

One reason why special relativity cannot be true is that time dilation is a fallacious concept. It is because the relevant definition of time is a standard of measure for comparing relative rates of change.
SvaraRaderaKnowledge of basic informal logical fallacies is sufficient to refute special relativity considering that reifying abstractions is fallacious and pure fiction. So when the ordinary person can understand better, why is it still accepted. Well, Rutherford was silenced.
SvaraRaderaXinhang Shen makes an unnecessarily complicated discussion about universal time and clocks, when the real issue is that we must apply a single standard unit of measure for time in order to have a consistent comparison of rates of change. That is really what time is, so it cannot vary or it ceases to provide a means of comparing rates of change. It is the "yard stick". It is an abstraction. Don't drag in the whole confused controversy about universal time.
SvaraRaderaI find that Douglas Reinhardt's books on linguistics and physics are very helpful in clarifying the issues. He emphasizes the simple speed equation for understanding special relativity and the M-M experiment. “Then the idea of combining space and time into spacetime, which then becomes a kind of ethereal fabric which is warped by massive objects was just too metaphysical for me to call physics. I had learned in my study of linguistics that the way people of a culture perceive the world is largely influenced by their language. I have come to believe that the primary problem with Relativity is faulty use of language, especially in the way space and time are conceived.” [Reinhardt, Douglas. THE 3Rs: REASON, REALITY, AND RELATIVITY: A Linguistic Analysis of Relativity (Philosophy of Science Applied to Modern Physics) (p. 6). Kindle Edition.] “So, yes, the problem is semantic, and the solution is semantic as well.”[Reinhardt, Douglas. THE 3Rs: REASON, REALITY, AND RELATIVITY: A Linguistic Analysis of Relativity (Philosophy of Science Applied to Modern Physics) (p. 12). Kindle Edition.] “It is obvious by now that my concept of space is like that of Tesla who said that space has no properties because it is nothing and “nothing” can have no properties.” [Reinhardt, Douglas. THE 3Rs: REASON, REALITY, AND RELATIVITY: A Linguistic Analysis of Relativity (Philosophy of Science Applied to Modern Physics) (p. 18). Kindle Edition.] “8) A light-year is a standard measure of distance in space. If the speed of light is constant in the vacuum of space, then a light year is a standard, unchanging unit of distance in space. If one considers the formula, distance = speed/time, then speed and time are constant for light, which would make distance or space constant thus refuting relativity’s claim that space can expand or contract. And, if space were elastic, it has shrunk to the maximum degree with light.” [Reinhardt, Douglas. THE 3Rs: REASON, REALITY, AND RELATIVITY: A Linguistic Analysis of Relativity (Philosophy of Science Applied to Modern Physics) (p. 23). Kindle Edition.] I have argued that gravity and acceleration affect timepieces but not time itself. If you accelerate a pendulum clock or place it in a different gravity field, then it will tell a different time, not because time has changed but because the timepiece has been changed. I have read that since the moon has less gravity than the earth, a pendulum clock would swing more slowly, but in GR, time is supposed to tick more slowly in heavier gravity.” [Reinhardt, Douglas. THE 3Rs: REASON, REALITY, AND RELATIVITY: A Linguistic Analysis of Relativity (Philosophy of Science Applied to Modern Physics) (p. 53). Kindle Edition.] “If one defines time as an abstraction or mental construct which attempts to identify a standard rate of change by which to judge the rate at which other things change, then time dilation seems to reduce to absurdity."-p.70;
SvaraRaderaWe can define time from the speed formula. Speed= distance over time. So Time equals distance over speed. [60 miles/2 hours= 30 mph;so 2 hrs= 60/30]. This is the pertinent definition of time to apply. So this makes time a comparison of rates. To compare rates of change we need a standard of measure. Time dilation and space contraction are purely ad hoc inventions. They also violate Occam's razor. If time is dilating then the standard of measure is changing and that's just cheating.
SvaraRaderaAs for Einstein as poker player, he was a propagandist.
SvaraRaderaVery interesting claim that the use of GPS indicates that SR is fake. The claim should be easy to verify, so I tried to google it. But I came a cross the opposite claim, i.e that SR is used to calibrate the clocks, and if left uncompensated, it would cause navigational errors that accumulate faster than 10 km per day.
