Steffen's Polyhedron

I like the "Dark Integers" series of stories written by Greg Egan. They might even have inspired Liu Cixin to write in Death's End that somewhere deep in the universe, some powerful civilizations would weaponize physics laws, and some other even more powerful civilizations could even weaponize mathematics laws.

Egan's dedication to going above and beyond justifying the worlds he creates still astounds me. I hope they make one of his books into a movie (Permutation City is my favorite and would be very topical given today's obsession with AGI).

Note: the same Greg Egan who wrote these https://www.amazon.de/s?k=greg+egan
