When a star burns out and collapses under its own weight, the space around it crumples into a black hole. At the center, according to textbooks, lurks a singularity — a point where density becomes infinite and the laws of physics break down.

When two black holes merge far away, we receive a tremor of space — gravitational waves. Usually, they are described by Einstein's equations, but what if gravity works differently at the tiniest distances? The authors took one such hypothesis — Hořava–Lifshitz gravity.
