Question

who discovered the flattening of the earth at the poles​

Answer 1

Answer:

This meant that gravity must be weaker at Cayenne than at Paris. Sir Isaac Newton and Dutch mathematician Christiaan Huygens used this discovery to prove that the Earth is not a sphere but is actually flattened at the poles (an oblate spheroid). Thus, Cayenne is farther than Paris from Earth's centre.
