unsolvability
Cannot be resolved
Unsolvability is the quality of having no solution.
In mathematics and logic, it refers specifically to problems that can be proven impossible to solve—not merely difficult, but demonstrably beyond resolution: Turing proved the unsolvability of the halting problem.
More loosely, it describes any situation that seems to have no way out: the apparent unsolvability of the conflict.
