It's a gap between physics and mathematics. Undecidable statements exist mathematically, but don't exist physically: mathematics and physics have different concepts of existence. Ironically, even mathematical universe hypothesis deliberately limits mathematics-as-physics to specifically resemble physics of a spontaneous material world, and this limitation is just an axiom.
