As I have been discussing in another thread do we know who blew up the Tardis in series 5?
If it has been explained my interpretation is that the silence blew up the Tardis to attempt to kill the doctor. The alliance thought it was the doctor and so they tried to capture him to stop him form destroying the universe. Presumably the Silence didn't know blowing up the Tardis would destroy the universe. Which does seem a bit odd considering how much they know.
