1) it effectively repeats the myth about seeing the Great Wall of China from the Moon. You would only be able to discern street lights from Low Earth Orbit.

2) The Moon is tidally locked and goes round the earth in about 30 days, not a few minutes as was implied by the graphic of the rotating Earth as lights go out.

3) The moon also stabilises the Earth at its 23 degrees off the vertical which gives us the seasons, so an increasing moon mass would do more than mess with the tides.

4) Episode ignores accepted theory for origin of the Moon, namely a glancing blow collision with a planetoid called Thea. This was confirmed by samples brought back by the Apollo missions, backed up by Russian samples.

Since when has Doctor Who stuck to scientific fact?

It's called science FICTION for a reason.
