186. The fact that people sensitive to motion sickness do not get sick standing still on Earth prove that it is not a sphere spinning at 1000mph

"People sensitive to motion sickness feel distinct unease and physical discomfort from motion as slight as an elevator or a train ride. This means that the 1000mph alleged uniform spin of the Earth has no effect on such people, but add an extra 50mph uniform velocity of a car and their stomach starts turning knots. The idea that motion sickness is nowhere apparent in anyone at 1000mph, but suddenly comes about at 1050mph is ridiculous and proves the Earth is not in motion whatsoever." 




Add motion sickness to the long list of things that Dubay does not understamd

To be fair to Dubay, the exact mechanics of motion sickness are still being debated, and the effects differ between people, but most agree that motion sickness is caused by the mixed signals sent to the brain by your senses including the inner ear, which detects gravity, acceleration and its direction.

Your ability to anticipate the acceleration that you experience also appears to have an effect.

Car sickness seems to be caused by some of your senses thinking that you are stationary, while others tell you that you are in motion.  This mismatch is made worse by acceleration, but can also occur at constant velocities.

E.g. A back seat passenger in a car has the car interior dominating their view.  Since they are moving in sync with the car their eyes are signalling that they are stationary while their inner ear and body in general can sense vibration and their hearing are telling them that they are in motion.  When the car speeds up or slows down, or goes around corners this mismatch gets worse, and motion sickness gets correspondingly worse.

Front seat drivers experience less motion sickness because they are less focussed on the car’s interior so their senses match better, and also because they can better anticipate any acceleration due to speed changes and turning.  It is no coincidence that drivers hardly ever suffer from car sickness.

Standing still on a spinning earth, there are no mismatches in the senses.  Their eyes tell them they are stationary and their inner ears are not experiencing any acceleration so that fits in with what their eyes are seeing.  Hence no motion sickness.
