If I wanted to know what Bard or ChatGPT had to say about this, I would ask them.
One can't solve 3-body problems without Superfluid Quantum Gravity, thus this that I took the time to add is very relevant.
Not worth helping then.
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.
