You literally are trying to disprove that the latitudinal rotational speed of the Earth does not influence rapid transition from daylight to darkness at the Equator and slower towards the geographical poles Unless you have not forgotten it is daily rotation which causes the transition from daylight to darkness while the spherical characteristics of a rotating Earth generate the latitudinal specifics of that transition to believe otherwise is truly remarkable It is that twilight effect and the table of values which indicate the Earth s rotation through 360 degrees in 24 hours and until you find a way to incorporate the 23 hour 56 minute 04 second value for rotation through 360 degrees you will have to consider that sidereal time value and the reasoning behind it as invalid 92 251 255 14
