That’s rare, but we might not spot the next one until it’s too late for existing technology to stop it—especially if it’s a comet.

Gravitational waves are ripples in the curvature of spacetime that propagate as waves, generated in certain gravitational interactions and travelling outward from their source. Continue reading “What are gravitational waves”
