You mean the books where magical aliens warp the fundamental constants of the universe to eliminate physical dimensions? Even if you skip past that to the underlying dark forest idea, it’s an argument based on pure faith with zero evidence to support it. You need an all power malevolent society that works on a time scale of thousands if not millions of years, and then nit only eliminates another society for “reasons”, but also then also perfectly covers up its own existence, because there may be some other bigger bad out there. It’s about as convincing as the unicorn that’s always right behind you, but everyone ignores because unicorns are super dangerous.
