The nature of science is extrapolation. The weights dropped by Galileo off the tower of Pisa were not said to be relevant only to those weights at that location - but extrapolated into a system whereby one could accurately predict the rate at which ANY object would fall at ANY location

The extrapolation to "ANY location" includes the moon and Mars right?

According to the system it could be predicted that each would fall at the same rate as the other, but slower than on earth. F=ma^2.
