Newton's Theory
Newton's theory explained (through math) that there was gravity everywhere not just on earth. This differed from past ideas because they thought it was only "available" on earth (gravity). -
Cavendish Theory
Believed the same thing as the Newton Theory, used the math to solve gravity's constant. -
Einstein's Theory
