Howling:The oldest question In The Whouniverse

according to dorium Dr who is the oldest question in the universe so it must be a very big and important one and silence will fall when it is answered now i am very supportive of the Silents Will Fall theory becuse i can just imagain on the fields of trenzalore river(she knows the name) saying "dr who" with silents closing in on all sides then the doc just whispering in her ear the answer then a burst of energy destroying all the silents....... however the doc may not be the one to answer as i stated before river knows so what if she is the one to answer? and the silents are just going on a wild goose chase after the doc while they have created there doom in the form of river it is a posibility but just wondering what you guys think
