You know stopping space is the correct solution. After all, the only way to tell if something is frozen is to see if other things are moving relative to its stillness, and for that, time has to keep passing. So, how to stop space? Sure, it's simple enough to stop molecules by making things colder, but how do you stop actual space, the empty volume around them? Not to bog things down with pesky details, you find a method to do just that using only what you had in your pockets, some nearby sticks, and an adorable quail feather that was by your feet. A bit of fiddly-widdly and soon you have frozen rigid the folds of the fabric of space. This immediately ends gravitational fluctuations and guarantees Earth's orbit around the sun will slowly extend outwards. You are able to at last join the people in camp and have a chill hang out, and it's chill because the Earth's slowly increasing orbit gradually lowers the temperature. As a new eternal night begins you wonder to yourself whether "fiddly-widdly" is a real expression or if you just made that up.
