You are overly optimistic.
unfortunately we really know almost everything and we can tell with almost 100% accuracy what is possible and what is not. (At some degree we can even approximately tell how it is possible)
Sure there is still some fundamental stuff we don't know it but unfortunately we cannot even theoretically access it so it is irrelevant.

p.s.
I am not talking about knowledge on how to build quantum computer or fusion reactor.
I am talking about fundamental knowledge which explains how all existence operates.
This is like knowing how computer CPU works, not how all software using that cpu works.
