The article mentions &quot;few known exact solutions&quot;. There are actually quite a number. Most are from after 1950.<p>Cambridge University Press has two good books: Exact Spacetimes in Einstein&#x27;s General Relativity (Griffith &amp; Podolsky) - good readable (if you speak GR) account of the more common solutions Exact Solutions of Einstein&#x27;s Feild Equations (Stephani, Kramer, MacCallum, Hoenstelaers, Herlt) - encyclopedic, authoritative and mathematical. In my case an aspirational purchase

For anyone interested in this topic: there are commentaries on this paper as well as Gödel&#x27;s own lecture on this in Volume III of his Collected Works.

So to solve physics, you don&#x27;t just have to be smarter and more creative than Einstein, but than Einstein and Godel combined.
