Abstract Why Earth daily motion 2.58 mkm = The moon orbital circumference at apogee radius r=0.406 mkm (Apogee radius is the longest distance between the Earth and Moon)? Conclusion: The Moon orbital motion depends on relativistic effects are found in the moon orbit. Introduction Paper Main Hypothesis: The rate 1.0725 is found by lorentz relativities effects (Apogee orbital Circumference 2.58/Moon orbital circumference 2.41) =1.0725 The Hypothesis Explanation: (28.3 deg Neptune axial tilt/ 26.7 deg. Saturn axial tilt)= (26.7 deg. Saturn axial tilt/ 25.2 deg. Mars axial tilt) = (25.2 deg. Mars axial tilt/ 23.4 deg. Earth axial tilt) =1.0725 The previous equation explain the hypothesis 28.3 degrees (Neptune axial tilt) is the main value which is contracted by lorentz effect (1.0725) to produce 26.7 deg (Saturn axial tilt) which also is contracted again to produce 25.2 deg. (Mars axial tilt) and then contracted again to produce 23.4 deg. (Earth axial tilt) so these 4 values are one value but the difference is found by relativistic effects (The prove of this rate 1.0725 will be discussed in point no. 3) -The moon orbital motion The moon moves 2.58 mkm daily = Earth motion daily (otherwise they will be separated from each other) If there's no relativistic effects in the solar system, the moon should be seen as a bright stationary point in the sky because Earth and Moon move by the same velocity. But Because of the relativistic effects this value (2.58 mkm) will be contracted with the rate 1.0725 to produce the value 2.41 mkm (Note please/ The length contraction rate 1.0725 we have discussed clearly in my previous paper) So the moon daily motion =2.58 mkm but this value is seen =2.41mkm (because of lorentz length contraction phenomenon) The difference between both = 0.17 mkm which causes The Moon Daily Displacement (0.17 mkm = 2 x 88000km) Why the difference 0.17 mkm = 2 x moon daily displacement 88000km? may that occur because of the motions opposite directions.
