Apropos this conversation, this document might be of interest:
It's a French Sigma 2 publication. One of the "conclusions" is:
Do known Laws explain everything? It seems that some cases are beyond known science
and may prompt research into extensions of known laws or lead to other discoveries,
confirming alternative theories, now qualified as speculative.
There's no doubt about this conclusion, it's even a truism, wikipedia lists a lot of 'unsolved problems in physics, chemistry, biology, mathematics etc. etc' (those page are well worth a read if you're interested).
But this does not mean that some discovery will ever allow us to overcome the basic physical limitations we know exist (indeed, future discoveries could just as well have the opposite effect and introduce new limitations to what we can possibly do). There's a long thread somewhere here on Metabunk where this has been discussed, 'UFO and the laws of physics' iirc.
