An old science fiction novel, originally published or reprinted in paperback in the 1960s, in the English language.
The first expedition to the moon eventually discovers that the reason why it is dead is because it is in a time warp that speeds up time many times and thus is billions of years older than the Earth.
At the end, the time warp is accelerated many times and the entire moon disintegrates.
I don't remember, but I think there might be a machine that speeds up time on the moon and because of some conflict or danger the Earth explorers turn it up several times which causes the whole moon to disintegrate.
Doing so would seem to kill the explorers with rapid aging but maybe they were immune for some reason. And I don't remember what sort of threat or danger could exist on a moon that was dead and unchanging.
