Well, once they get that Quantum Logic thinker dialed in and realize that they aren't hitting zero because of chronic distortions from the future, not to mention their ice pit being bombed by the Logologists I bet they will be able to hit zero finally.

Maybe this leads credence to the theory will are living in a metastable false vacuum.

If so, screwing around with this is a bad idea.

This is more proof that we live in a computer simulation. This is nothing more than an overflow error.

They will declare the cause to be "dark cold" like they do to cover up all their other math errors.

Here's the wiki: Negative temperature

But "negative temperature" != "below absolute zero"

Negative temperature is not a new phenomenon, in lasers it's called "Population inversion" and it's how you get lasers to do their thing.

Think of it in terms of gravity. If you have gravity in one direction, you can call it "positive" gravity, and you're pulled towards the Earth. If you have "zero" gravity, you're not pulled anywhere, and just float. If you have "negative" gravity (anti-gravity), you are pushed away from the Earth. This doesn't mean you are feeling less force than the zero gravity situation, just that the force is pointing the other direction than you designated positive gravity.

Similarly, negative temperature is when the particles naturally settle uphill, rather than downhill, as it were.

As a comment suggests, lasers have had negative temperature for decades. Infinite temperature has all energy states of a system populated in proportional to some bizarre quantum statistical numbering scheme. Positive temperature has lower energy states disproportionately occupied, negative temperature has higher states occupied.  Traditional lasers rely on an excess of electrons in high energy states.
