Let's say that our moon is actually made of cheese, except for the outer layer of rock. Although there are no microbes or oxygen, temperature is still a factor in its spoilage. Is there a formula that links temperature to pressure that could describe how long it would take for the moon to spoil?

Part B: if and when it does, could we tell from Earth?

  • $\begingroup$ Maybe Tα/ρcP? I don't know enough physics to determine whether that would be applicable here. $\endgroup$ – DonielF May 8 '17 at 20:46

    $\begingroup$ @Secespitus I question the validity of those answers. Even without bacteria, the excessive heat and excessive coldness of the moon combined with the raw radiation would render the cheese inedible rather quickly. It is questionable if the cheese would still be identifiable as cheese after changing composition so much. $\endgroup$ – user2259716 May 8 '17 at 20:48

    $\begingroup$ The high temperature, pressure and time combine to turn the cheese into goop. At first the cheese will seem to be keeping well but slow chemical reactions release heat that can't escape. After a few million years the result resembles crude oil. $\endgroup$ – Donald Hobson May 8 '17 at 22:35

    $\begingroup$ @DonielF five. Hi, welcome to Worldbuilding! I know this isn't your first post here, but I hadn't noticed you before. :-) (BTW, if you edit to add the info I asked about, your question will automatically go to the reopen review queue.) $\endgroup$ – Monica Cellio May 9 '17 at 3:59

Space is cold, it can easily be -170 C° Your cheese will not be spoiled for a hell of a long time. Cold boiling is because of a low pressure, however, we're in a celestial body, it has a lower gravitational force, but still. Also, that water isn't alone, it's bound to various other materials too. Water-containing life can and will survive in space without any special equipment, and cheese isn't even alive in the first place.

Cosmic radiation is a factor, but I don't think it can get through the rock easily.

So yes, You can has a cheezburger.

The second part is an obvious No, We can only assume, and a yes, we can easily be almost sure, that cheese hasn't got spoiled (entirely).

Friendly note: For cold boiling, we need the stuff to have energy, so it would wiggle around enough, low pressure will lower the energy wiggling needed to break free, however in cheese and ice, there's a stronger connection between the atoms, thus will boil if they're given more energy and not just low pressure.

Spoiler: Absolutely nothing. :)
