دعوة إلى الإخوة المختصين من أجل النظر في دعاوى القائلين بمركزية الأرض للكون! (تااااني)

Quote: The rotation of the Earth has no effect at all on airplane flights. The Earth, its atmosphere, the people on its surface, and the airplanes in the atmosphere all rotate at exactly the same speed. Flying west is no slower or faster than flying east, and distances are the same in both directions. An observer thousands of miles above the North Pole could look down and observe aircraft flying in the Northern Hemisphere. He would see that eastbound aircraft move more quickly than westbound aircraft. He would also see, however, that the Earth moves towards the east, along with its atmosphere and everything else within, so even though an eastbound aircraft travels faster, everything around it is moving in the same direction at the same speed, so the elapsed time to get to destination when flying east to west is the same as it would be when flying west to east. For this reason, from the standpoint of the Earth, the airplane, the atmosphere, and everything else on the planet, the distance and time involved in west-east flights are identical to those involved in east-west flights. An independent observer (one who is not part of this terrestrial system) would see differences, but the people on the planet would not. It's all a question of frame of reference. If your departure point or your arrival point is outside the Earth system, then the Earth's rotation is important; but when they are both on the Earth's surface and within its atmosphere, the rotation makes no difference. The Space Shuttle has to worry a great deal about the Earth's rotation when taking off or landing, because it spends time away from the Earth, during which it is not rotating with it. But an ordinary jet airliner never leaves the Earth's frame of reference, and therefore doesn't have to care. The Earth orbits the Sun, too, but unless you are traveling outside the Earth's moving frame of reference in its orbit, it doesn't matter. The Space Shuttle stays within the Earth's orbital path, near the Earth, and so its orbit around the Sun isn't very important. But interplanetary probes leave the Earth's orbit, and in their cases the movement of the Earth around the Sun becomes an important factor. The same could be said for the Sun's motion through our galaxy, our galaxy's motion through space, and so on.
