Sir Issac Newton is considered the brightest bulb in England.
Even though he wrote more about Alchemy and biblical timelines than modern science discoveries his thinking was brilliantly simple.
We always thought colored light came from inside a material but Newton simply place a prism in an opposite position to another prism and proved white light contained all the colors and turned back into white light when reunited.
Regarding the apple and Newtons theory of gravity it really had to do with his question of if the apple falls why does the moon not fall.
His thought experiment revealed that it was only a matter of horizontal velocity that kept the moon falling in an orbit.
Speaking of the moon, it used to be 20 times closer to Earth.
The tides it made at that close distance obeys a cube rule so the tides were 8,000 times stronger than today. The moon is tidally locked so only one side faces Earth but there will come a day when the Earth will also get tidally locked to the moon. By then the moon will be much farther away than today.
