QQC #3

"This was the suggestion that the Earth is not quite round. According to Newton's theory, the centrifugal force of the Earth's spin should result in a slight flattening at the poles and a bulging at the equator, which would make the planet slightly obsolete."

I think that it's weird that Newton has found so much evidence about the Earth not being round but it is. The question I have about this quote is what evidence is his research based off of? Because if there is evidence to prove his theory, then how come it is false?
