A beautiful solution of the gravitational 4-body problem. But keep watching, because it's not stable!https://twitter.com/simon_tardivel/status/1215728659010670594 …

This solution of the 3-body problem is stable, apparently:https://twitter.com/simon_tardivel/status/1215726342421041152 …

i’m not sure which is more surprising: that this is stable or that the other one suddenly isn’t!
-
If I knew enough physics I'd have some intuition for when these orbits are stable, but I don't.

Is there triple stars that have stable orbits like this in real universe? What are the chances of realization of this stable orbits?

The star nearest to the Sun is a triple star: a pair of yellow dwarfs (Alpha Centauri A and Alpha Centauri B) and a much more distant red dwarf, Proxima Centauri. A perfectly symmetrical system like this with 3 stars of the same mass is unlikely.pic.twitter.com/V01g5h95ju

Not stable but non-periodic?

It's stable: that means small changes in initial conditions do not amplify over time. But it's also nonperiodic.

3-body problem isn't stable. This similation only changes initial speed/position and keep mass equals. If you introduce few % of differences between mass the evolution turns more chaotic :https://photos.app.goo.gl/wthBh1VnWntGMGDz9 …

Astoundingly cool. It does appear (qualitatively) that the loop sizes are changing disproportionately, which would imply eventual instability - but fascinating regardless.
