Unfortunately, Albert Einstein had been poor in Astronomy when he was young. New finding you don't know before, Einstein proving method for his hypothesis in general relativity "deflection of light by the Sun" isn't scientific and deeply wrong. Einstein ignored refraction of light: ie. astronomical refraction and terrestrial refraction. Actually, the first experimental of general relativity by Arthur Eddington in the year of 1919 was error. That is why Einstein never received a Nobel Prize for Relativity.
Einstein proving method (EPM) via eclipse is 100 % domain of Astronomy, it’s not domain of Physics. Someone those who had been experiences in Astronomy: ie.measuring the altitude of celestial bodies using sextant, know exactly EPM isn’t scientific, the result will always be an error.
General relativity has been wrong since the beginning. General relativity violate the modern astronomy. General relativity violate the standard model of physics.
Einstein’s gravity is wrong. Gravitational lensing is false. Lensing is caused by refraction, not gravity. Gravitational redshift (Einstein’s shifts) is false. Redshifts is caused by refraction, not gravity. GPS doesn't need and doesn't prove general relativity.
And more ……..Time dilation, Shapiro delay is false. Time delay of light (Shapiro radar signal) is caused by refraction, not gravity ..(More info in the book: Albert Einstein Failed In Three Classical Tests, Eclipse 1919 and the General Relativity Theory). -
After watching a couple of lectures I'm really eager to keep going! Hope you'll post some more videos in the near future sir. Thank you from a mechanical engineer who loves physics and mathematics. (and who believes in relativity unlike those who developed the first GPS technology lol)

Alexander thanks a lot for the excelent lecture series you deliver in your youtube chanel. I would like to know what about the higher order gravitational redshift (called Shapiro delay), for instance, the extra time it takes for an EM signal to travel from a satellite to GPS receiver on Earth due to the spacetime curvature generated by the Earth itself?
