no. no and no
it has nothing to do with the frame of reference, it has nothing to do with seeing things around you. forget “dizziness, that was a bad way of putting the question, think in terms of “feeling” the turning.
the situation will be the same if the merry-go-round is located alone in outer space, just as the earth is
here is an easier way to look at the problem, instead of talking about human perception:
say you have a measurement device with you that measures centrifugal “force”.
although the merry-go-round (now relocated in outer space, off the earth)is rotating at a speed of say 5 miles per hour, and the earth is rotating at 1,000 miles per hour, the centrifugometer will measure over 10,000 (something like that, i didnt actually calculate it) times the amount of centrifugal force on the m-g-r than it does on earth. why is that?
if the m-g-r would move at 1,000 miles per hour (as does the earth) you would be instantly and violently thrown off, even if the m-g-r had the same gravity as the earth does. why arent we thrown off the earth?
