#2For anyone interested in this topic: there are commentaries on this paper as well as Gödel's own lecture on this in Volume III of his Collected Works.

#3Does this mean that traveling faster-than-light can be considered a form of time travel?

Yes, which is why sci fi scenarios in which ships whiz between star systems will never, ever, ever happen.

#5So to solve physics, you don't just have to be smarter and more creative than Einstein, but than Einstein and Godel combined.

Yes, which is why sci fi scenarios in which ships whiz between star systems will never, ever, ever happen.
Also, any kind of instantaneous communication.
Unless the theory of relativity is superseded by something quite radically different.

High school educated talking here.
Does Quantum Entanglement have any promise for instantaneous communication (theoretically) ?

Nope, you can't pass information through entangled particles. All you know when you measure you particle is that the other one will turn out the same (or is likely to, I forgot the exact details). This does not lend itself to any communication protocol.

#9The article mentions "few known exact solutions". There are actually quite a number. Most are from after 1950.
Cambridge University Press has two good books: Exact Spacetimes in Einstein's General Relativity (Griffith & Podolsky) - good readable (if you speak GR) account of the more common solutions Exact Solutions of Einstein's Feild Equations (Stephani, Kramer, MacCallum, Hoenstelaers, Herlt) - encyclopedic, authoritative and mathematical. In my case an aspirational purchase
