Yes I agree that assuming both take the same amount of time the grasshoppers would bother appear above my head how ever the grasshopper 100feet away would (assuming it takes a perfect circular motion based on your calculation being Pi*r since its a semi circle) also appear 100feet over head while the other one would be 10 feet above my head?
The last point I don't understand, a point in space to which you didn't know how far away it was I presume means you are discussing the globe model, if that's the case then I will just skip over it as I am not interested in that topic, I wish to understand the FE model not discuss the Globe Earth.
Now if the last point was about FE then I am more confused as the Wiki suggests that the Sun is 3000 miles away so it's a known distance, even if its an approximate.
If you could elaborate what you meant by your final point that would be super helpful thankyou
Sorry adding an edit as apparently I didn't see your last sentence (still getting used to this site), I may be new at this but my calculations determined there would be around a 250% difference in speed between 2 locations New York Summer and Melbourne Summer, I would elaborate but I just made the whole video on it, I feel a 250% speed difference would be extreme enough to notice?
