   6 de may. de 2024 · Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. A gravitational wave is an invisible (yet incredibly fast) ripple in space. We’ve known about gravitational waves for a long time.
