Einstein relativity is false

Einstein relativity causes twin paradox in GPS clocks, so wrong.

(Fig.1)  Two satellite clocks A and B moving around the earth cause twin paradox, which shows Einstein relativity is wrong.

GPS does Not use Einstein relativistic time dilation, which is useless, paradoxical.

Contrary to the standard explanation, GPS satellite clocks do Not use Einstein relativity which is said to cause time difference between GPS satellite and the earth's receiver clocks ( this-lower-conclusion,  this 5~6th-paragraphs,  this p.1-introduction ).

This extremely tiny time difference by this (fictional) relativity is meaningless, because the receiver's cheap clocks often cause large time errors (= irrelevant to relativity, this p.2-1st-paragraph ), and the time difference between satellite's and receiver's clocks can be corrected by using 4 satellites without using Einstein relativity ( this p.7 ).

Furthermore, GPS clocks cause errors by a lot of factors such as atmosphere (= so GPS clock time disagrees with relativistic prediction, this-middle ), which must be constantly corrected by being compared with the earth ground station's clocks ( this p.2,  this p.4 ) irrelevant to relativity.

GPS satellite clocks causing twin paradox disprove Einstein relativity.

When two satellites A and B are moving around the earth at the same velocity v in the opposite directions at the same height (= distance between satellites and the earth's center is always r ), Einstein relativity causes twin paradox in these satellite clocks.

From the perspective of a satellite B (= B's rest frame ), the satellite A's clock is moving and running slower according to Einstein special relativity.

But from the perspective of a satellite A (= A's rest frame ), the satellite B's clock is moving and running slower.

↑ Which satellite clock A or B is moving and running slower is paradoxical (= called twin paradox ), so Einstein relativity is wrong.

In this case, general relativistic (= gravitational ) time dilation is irrelevant, because the distances between the earth center and two satellites are always the constant r, causing the same gravitational potential and No gravitational time dilation difference between two satellites A and B.

Furthermore, from the perspective of the satellite A (or B), the satellite A (or B ) is free-falling (= called inertial frame ) where the earth's gravity is canceled by centrifugal force, so No general relativistic time dilation is involved in comparing these two satellites' clock time, and only special relativistic time dilation (= moving clocks run slower ) and twin paradox occurs ( this p.2-left-upper,  this p.2-left-2. ).  → Einstein relativity is wrong.

Sagnac effect showed light speed changed by observers' motion, which contradicts Lorentz transformation and relativistic mass (of satellite ), disproving Einstein relativity.

In fact, Einstein relativity, Lorentz transformation based on the constant light speed c measured by any observers are proved to be wrong by Sagnac effect where the light speed is faster (= c + V ) or slower (= c - V ) than light speed c by the earth spinning speed V.

From the perspective of satellite A (or B ), all things appear to be rotating around the earth in the opposite direction, which is the rotating (= accelerating ) frame (= rotating coordinate ) involving general relativity.

Solving twin paradox needs the unrealistic faster-than-light satellite, so Einstein relativity is false.

The problem is Einstein special relativity based on Lorentz transformation contradicts the special relativity derived from the general relativity (= rotating frame of very large radius corresponds to linear motion of special relativity ), which self-contradiction disproves Einstein relativistic theory.

General relativistic rotating coordinate allowing the light speed to be changed by the earth motion disagrees with Einstein relativity based on the constant light speed c.

Because, according to Sagnac effect, when two satellites A and B are moving at a very high speed of 0.6c in the opposite direction, the satellite A (or B ) appears to be moving faster than light (= 0.6c × 2 = 1.2c,  c is light speed ), and the relativistic mass of this faster-than-light satellite becomes unrealistic imaginary mass, seen by the other satellite B (or A ).

If general relativistic Sagnac effect is right (= light speed is changed by observer's motion, which contradicts special relativistic Lorentz transformation, this p.7-1st-paragraph,  this p.2-right-middle~lower ), the observed light speed must be changed not only by the earth spinning (= this is experimentally observed ) but also by the satellite's velocity (or the earth's rotating around the Sun = which is also rotating frame ), which is not observed, hence, relativistic interpretation of Sagnac effect is self-contradictory and wrong.

Sagnac effect where light speed is changed only by the earth's spinning (= Not by the satellite's velocity nor by the earth rotating around the Sun ) can be explained only by the medium (= light aether ) moving with the earth (= light speed is c inside this earth medium ), but the earth medium is unfixed to the earth's spinning (= light speed is changed by the earth spinning, as observed in Sagnac effect ) like the atmospheric molecules.
