One planet orbiting a star? No problem. Two or more planets orbiting a star? Now that's one of the biggest problems in astrophysics.

"Just because they're theoretically stable doesn't mean they'll stand up to the many other forces present in a real star system."

And just because the solar system has been in a stable resonance for 4.5 billion years doesn't mean it's completely stable. It's actually weird that it's lasted this long.

Amazing how the science hasn’t been settled for over 300 years on this, but magically it’s settled in days, no hours now when it comes to climate and Covid. What a bunch of slackers these mathematicians have been.

2 + 2 = something like 4

Hmm...at what point is one solution different from another?
Obviously if they’re all nonintersecting ellipses is the simple solution.

I’m having a hard time imagining 12000 different solutions with 3 bodies.

Earth, moon, sun is a three body problem, and not a trivial one. It not necessary for three body problems to have an initial condition of three bodies being mutually at rest. The initial conditions must include the position and three dimensional velocity vector of each.

Three body problem? Is that another name for a Chinese sandwich?

I’ve heard that weightlessness obtains to the center of the earth. Does the same hold true of every physical object, that is has a weightless gravitational center? I have also wondered how many axes in motion are possible at the same time on a single sphere.

"Mathematicians find 12,000 new solutions to 'unsolvable' 3-body problem"

Didn't Teddy Kennedy and Chris Dodd solve that equation decades ago with the help of a waitress that happened to be studying theoretical mathematics at the local university?

I suspect some of the ‘stable’ orbits are more like fractals than folks are willing to admit.
