> One can't solve 3-body problems without Superfluid Quantum Gravity

The article (from 1962) does not predict 3-body accelerations of large masses or particles using current methods (probably because they had not yet been developed at the time).

(Ironically, in context to the rejection of AI methods to summarize superfluid Quantum Gravity for the thread's benefit (and not my own),)

N-body gravity problems are probably best solved by AI methods; it is well understood that there are no known closed-form solutions for n-body gravity problems.
