For example, I'm a little concerned about exactly how much water would be required to fill a hole down to the centre of the Earth.
A 5m radius tunnel to the centre of the earth has a volume of 500 million cubic metres. According to http://www.the-river-thames.co.uk/weather.htm the flow of the Thames at Teddington during winter is 30 million cubic metres a day (though I don't know if this includes some of the same water more than once, due to the tide).
It didn't need to *fill* the hole, but it is silly to to fill enough to empty the London stretch through a small aperture in a short time. But only *too* silly if you are curmudgeon.
Admittedly this was done on back of an envelope, I don't understand how weirs work and the copy of this in my LJ was made private as soon as I realised my first pass was out by a factor of a thousand.
Niall: the channel tunnel isn't filled with stone, even though that is what surrounds it. That is why it is a tunnel. There's no reason why a tunnel to spidery spaceship hard-centre of the Earth should have lava in it. Assuming they used some sort of special rays when constructing it. Or a wizard did it.
I was slightly freaked out by the Tardis being there while the Earth was forming, so obviously in the way of various bits of rock and dust that really need to go in exactly the right place...
That precision reminded me of the joke about the museum watchman who told visitors that the T.Rex exhibit was 64 million years and three months old. They told him it was 64 million years old when he started there, and he had been there three months. Before the scene had finished I had rationalised it thus: the TARDIS never materialises inside a solid object, so he set the co-ordinates for the centre of the Earth (accounting for the Earth's motion) and simply kept winding the dial back until the moment it would let him materialise. Then set the co-ords one mile away and one minute earlier to see what changed. That is what I would do.
Torchwood was good fun, thought there was no excuse for lifting *shots* from F**** C*** in addition the theme; the writing and direction being apparently disconnected projects (one treating them as supercool, one treating them as an idiotic vanity project of Queen Victoria) has been Torchwood's biggest problem all season, along with Barrowman's on-screen out-takes.
