    Question The Three-Body Problem - closer to a solution ?

    Is the three-body problem in astronomy closer to being solved, or at least given a dirty answer? Some think so.

    The actual paper, using statistical averages to resolve the problem:

    Quantum mechanics might prevent the three-body problem from ever being resolved.

    The authors noted that this is not an exact general analytic solution, and never will be if I understand correctly. What they have done superlatively is to develop powerful tools to add to the mathematical toolbox for finding useful solutions to any desired low level of uncertainty.

    If I remember, it's been mathematically proven that there is no analytical solution to the generalized three-body problem.

    How do things fly? This explains it all.

    Actually they can't: "Heavier-than-air flying machines are impossible." - Lord Kelvin, president, Royal Society, 1895.

    No general analytical solution - there are a number of special case solutions. There is also a series based approach that is wildly impractical.
