The idea of apocalypse or at least the end of days is bent within a context of what people are willing to fight for but also the ruts they tend to get into. In "The Gravity", two brothers connected by a tragedy and comeuppance in their youth grow into a strife that holds them together as a cosmic event that might or might not destroy the whole world in a matter of days hangs over their head.

The aspect of heat as a perception of change and growth and eventual disassembling of society is a real and practical fact. "The Elderly" takes this but changes it to a chaotic tome of people knowing what is coming and painting it in almost a reversal rapture.
