This isn't really on topic (then again, this thread isn't on topic), but 
I have an idea.  The Earth spins (I know that much).  If spin produces 
centrifugal force, wouldn't we be pulled slightly away from the center 
of the Earth?  And wouldn't a person at the equator weight less than the 
same person at the north/south pole?  At first I thought that this would 
be true, but then I thought about gravity.  If gravity curves space, the 
Earth's gravity might curve space so that we aren't technically 
spinning, just travelling in a straight line.  Therefore, there would be 
no centrifugal force.  Can anyone verify my conclusion?
