Re: There's something wrong with the gravity
The moon *had* to be magically heavier because simulating 1/6th gravity while everyone is walking around (and The Doctor was playing with his yo-yo) would be far too costly for a BBC budget.
In order to give the moon the same surface gravity as the Earth you'd have to add 6 times the Moon's mass without making it any larger. That would also give the Moon a density similar to uranium, so what on Earth (sorry) was the creature made of?
