Gravity isn't instantaneous—it travels at light speed
Gravity isn't instantaneous; it actually obeys the cosmic speed limit. When massive objects like black holes violently collide, they send literal ripples through the fabric of spacetime. These gravitational waves propagate outward at precisely the speed of light, proving Einstein right once again and making Isaac Newton's instantaneous gravity look utterly ridiculous in retrospect.
