[0:00]One of the greatest works of science ever is Principia Mathematica. In there, Newton unleashes the three laws of motion, the laws of gravity.
[0:13]He's figures out how the solar system works. He's figuring out how do these planets sustain their orbits? Are they pulling on each other and in what way and how?
[0:24]He figures all this out, but wait a minute, every time Earth goes around the backside between the sun and Jupiter, Jupiter's going to tug on it a little bit.
[0:32]Comes back around again. Jupiter tugs on it again. Jupiter has a strong gravity. What's going to ultimately happen to Earth's orbit?
[0:39]In this scenario, Earth's orbit will become more and more elongated. The gravitational tug of war between the sun and Jupiter will yank Earth out of its orbit, destabilizing the solar system.
[0:50]Not only Earth, the other planets as well. He said, oh my gosh, this will take time, but clearly the solar system is stable.
[0:58]So, he writes, I can't understand why it's stable because I know my equations work.
[1:04]So, God must step in every now and then to fix things.
[1:09]Now, you got to be badass to invoke God at the limits of your knowledge when you explain so much with the equations you wrote.
[1:16]That by Newton was a god of the gaps invocation.
[1:21]He brought in God when there was something about the natural world he could not explain it, did not know.
