29. If the atmosphere were spinning eastwards at 1000 mph we would see, hear and feel it
“If the Earth and its atmosphere were constantly spinning Eastwards over 1000 mph, this should somewhere somehow be seen, heard, felt or measured by someone, yet no one in history has ever experienced this alleged Eastward motion; meanwhile, however, we can hear, feel and experimentally measure even the slightest Westward breeze.”
This is making the same point as proof 28. As before Dubay does not understand that winds are relative to the moving atmosphere.
By “experienced this alleged eastward motion” he presumably thinks we should be experiencing a 1000 mph wind.
If you were to stand still in a 10 mph eastward wind, you would feel that wind. If you then travelled eastward and sped up to 10 mph, the wind that you felt would become weaker and weaker and stop altogether when you reached 10 mph.
In the same way, we do not feel the 1000 mph eastward wind because we are also travelling eastward at 1000 mph because we are standing on a spinning Earth.
He may also be expecting us to experience the motion itself. When you are sitting on a plane flying at a constant speed, you do not experience the forward motion of the plane. You will feel forward acceleration on take off, upward acceleration when the plane starts to climb, but once flying level at a constant speed no forward motion will be felt.
In the same way, standing on the Earth travelling at a constant speed we would not expect to feel any forward motion.
For completeness we should also mention Coriolis force caused by the rotation which is far too weak for us no notice on such a large object as the Earth and the merry go round effect when our inner ear makes us feel unbalanced and even queasy because the tight arc is dramatically changing our direction. However on a spinning object as huge as the Earth, the arc is so large that we are unable to detect that motion.
