Yes, but in one of the later episodes, we find out that the cracks started out on the day of their wedding. It's all to coincedental.
Anyone else reckon Rory is the cause of the cracks in time & space? Amy has chosen him, but I don't think she'd abandon the Doctor for him, which will make him ultimately try and destroy the Doctor so she has no choice.
Given that the cracks start on their wedding day, it has to have something to do with either them or someone they know.
Didn't Prisoner Zero escape through one of these cracks when Amy was young?
