Quantum Ruins: A Nanotech Civilization Declares War on Humanity

The Guixu civilization was born in the quantum foam layer of Earth's oceans. Its home planet is a topological insulator, and it relies on quantum tunneling to travel between stars. Materials scientist Lin Hai uses a scanning tunneling microscope to observe the Guixu civilization's nanotech sanctum, but in doing so causes a probability collapse in the timeline of quantum civilization. The Guixu envoy Mo Xian uses nanorobots to construct a quantum hologram, showing humanity the quantum black hole crisis that is about to devour the microcosmic universe.
