Howling:People and objects absorbed by the Time Crack

It's stated, or otherwise strongly suggested, multiple times in Series 5 that people and objects that are absorbed by the Time Crack "never" exist, i.e. are retroactively erased from the timeline completely. This supposedly explains why no one else remembers them. The problem is that even though they never exist in the first place, somehow, all the things that happened directly because of them still happen....only without them. Take Rory, for instance. After he's sucked into a Crack, it's said he never existed....would that mean that if you then went back in time to just before Rory was absorbed, you'd see the Silurian's gunblast striking empty air? If you went back to the Byzantium, would the camera looking into the ships' cargo hold show nothing where the Weeping Angel had been? Would the Doctor, Amy, River and the Clerics have then been running around fighting nothing? And then there's the Dalek invasion of 2009....Without the Daleks themselves, would buildings just blow up, and people drop dead in the streets for no reason? We know that the Earth somehow manages to carry on existing after the rest of the universe is retconned out of existence in The Pandorica Opens/The Big Bang, but it's still a bit silly, even if you do believe that events caused by things absorbed by the Crack still happen even after those causes never exist themselves. I'm sorry, but I find this whole concept to be one of the silliest ever presented on DW. 213.121.200.42 13:47, August 4, 2011 (UTC)
