The inner planets were all originally moons of Jupiter. (From algorithm)

This is not theory.
It is computational astrophysics.
The math is derived purely from a combination of essential Newtonian mechanics with a subtle infusion of quantum time from Planck. I just put the pieces of the puzzle together in the visual basic 6 programming laguange. Currently the youtube video has 8 upvotes and 5 downvotes (Oct 2021). The original video was published on youtube in January 2019.
