The cracks in the skin of the universe, don't you know where they came from? You don't, do you?Prisoner Zero

The Cracks were a series of splinters in the "skin of the world". According to Prisoner Zero, the cracks were in the skin of the universe. The pattern of the Cracks is always the same, and the cause remains unknown.

When discussing the cracks with Prisoner Zero, the Doctor stated that somebody must have opened the cracks. When he was asked if he knew what the cause was, the Doctor remained silent; whether he didn't know or wouldn't say is uncertain. Prisoner Zero said the Pandorica will open and silence will fall in relation to their origin.
