There are things that we cannot imagine because they are impossible (like a solution to Russell's set theory, since it is impossible to reach that solution because it is illogical.)
Some months ago, discussing with a user in this site, he said that although no one has reached that notion, it could be the case that someone in the future could achieve it, but he did not know the topic well enough to make any meaningful conclusion.

Maybe someone here could help me
So could we develop a notion of conceivability that would allow us to imagine all of these things? Even all things that do not exist or cannot exist or are impossible like a solution to Russell's set problem or a thing that is illogical but at the same time is logical or inventing a new logic (or illogic) system...etc? What would be needed to reach such notion of conceivability? A change in the laws of physics? Or just biological evolution in our brains??
