Breakthrough in predicting chaotic outcomes in three-body systems

https://phys.org/news/2024-02-breakthrough-chaotic-outcomes-body.html

This seems like a very big deal. I know there have been several conversations at DU about these types of problems, and of course "The Three Body Problem" by Liu Cixin.

A new study has unveiled a significant advancement in chaos theory, introducing a flux-based statistical theory that predicts chaotic outcomes in non-hierarchical three-body systems. This breakthrough holds practical implications for fields such as celestial mechanics, astrophysics, and molecular dynamics, offering a more efficient and precise approach to analyzing complex systems and enabling deeper exploration and understanding of chaotic phenomena.

The research is published in the journal Celestial Mechanics and Dynamical Astronomy.

The study led by Prof. Barak Kol from the Racah Institute of Physics at the Hebrew University validates a novel approach to understanding the dynamics of non-hierarchical three-body systems. The newly introduced, flux-based statistical theory demonstrated remarkable accuracy in predicting chaotic outcomes, paving the way for streamlined computations and deeper insights into complex systems.

The research aimed to confirm a theory regarding the behavior of three-body systems, proposing that chaotic outcomes in such systems can be predicted using a formula involving a chaotic emissivity function and the asymptotic flux, a known function. To measure this chaotic emissivity function, researchers conducted simulations, tracking millions of scattering events to distinguish between regular and chaotic scattering.

1. Florida GOP Chair Christian Ziegler, husband of the Moms for Liberty cofounder have worked on three-body systems, too.

I'm sure they can describe the chaos that results from such systems.

Maybe it will help in managing the plasma in the new fusion reactor experiments! We are on the threshold of endless energy for the world. Wouldn't it be swell to have no more conflicts over oil.

7. It could just as well go the other way, showing why current fusion schemes won't work.

Fusion may never be a practical energy resource for physical reasons we haven't yet discerned. It would be unwise to bet the future of our civilization and the health of our planetary environment on it.

5. If it holds up, this is a pretty big deal, and I suspect with broad applicability. The full paper can be found...

...here: Manwadkar, V., Trani, A.A. & Kol, B. Measurement of three-body chaotic absorptivity predicts chaotic outcome distribution. Celest Mech Dyn Astron 136, 4 (2024).

I downloaded it, but will not have time to look at it for a while.

Thanks for the post!

6. This could be a very important advance.

Thanks for posting.

I think there’s a chaotic emissivity function at play with the mess on my desk!
