It is important to note that, prior to Galileo’s telescopic observations, common belief in Europe was that the Moon and planets stayed up due to being made of a substance that was immune to falling down (i.e. did not experience the effects of gravity). Newton proved mathematically that all that was needed to keep them in orbit was gravity and the appropriate velocity.--[[User:Ijuinkun|Ijuinkun]] ([[User talk:Ijuinkun|talk]]) 15:44, 27 August 2023 (UTC) | It is important to note that, prior to Galileo’s telescopic observations, common belief in Europe was that the Moon and planets stayed up due to being made of a substance that was immune to falling down (i.e. did not experience the effects of gravity).
