Ligo has just seen his most important gravitational wave? | By Ethan Siegel | Start with an explosion! | February 2025

A mathematical simulation of deformed space-time about two fused neutron stars that result in the creation of a black hole. The colored bands are picos and gravitational wave channels, and the colors become brighter as the wave amplitude increases. The strongest waves, which carry the greatest amount of energy, come just before and during the…
