Physicists get close to taming the chaos of the 'three-body problem'

The article says, "So far, Kol's ideas seem promising. In a not-yet-peer reviewed paper posted to the preprint database arXiv in January, Manwadkar, Kol, Leigh and Alessandro Trani of the University of Tokyo held a battle royale to see how Kol's theory held up against other statistical three-body forecasts. They ran millions of simulations of mashups between trios of stars of different masses to see how often each star got kicked out of the group. When the stars have the same mass, the unpredictability of chaotic motion guarantees that each individual has a one-third chance of getting the boot — no fancy models required. "

My observation. What about the early solar system using the solar nebula and accretion disk? What about proto-earth before the giant impact with Theia, does the proto-earth get ejected or other bodies quickly? Interesting approach to three-body problem. Other reports I read involve N-body interactions. Asteroids in NEO or NEA locations are not stable over millions and billions of years but samples recovered on Earth indicate immense ages via radiometric dates. Could this new solution indicate a very unstable and chaotic early solar system that ejects many bodies including proto-earth and Theia, as well as small asteroids and meteoroids? Intriguing timescale possibilities could emerge here for the solar system compared to radiometric dates using chaos and ejections. These computer simulations did not exist in 1956 when Clair Patterson *fixed* the age of the Earth and solar system at 4.56 billion years old using meteorite radiometric ages and this *fixed age* also dates the Sun too.
