... a) What law of physics convinced us that the Moon had to have its own gravity? Newton’s law of universal gravitation says that all massive objects create gravity and so the moon qualifies. b) Could the Moon’s gravity affect us while we are still on the Earth? Yes. According to Newton’s Law of Univer ...
