Credit: NASA What causes gravitational waves? Gravitational waves squeeze and stretch anything in their path as they pass by. They travel at the speed of light (186,000 miles per second). Scientists call these ripples of space gravitational waves. These ripples would spread out like the ripples in a pond when a stone is tossed in. He believed that this kind of movement could cause ripples in space. More than 100 years ago, a great scientist named Albert Einstein came up with many ideas about gravity and space.Īlbert Einstein, official 1921 Nobel Prize in Physics photograph.Įinstein predicted that something special happens when two bodies-such as planets or stars-orbit each other. We’ve known about gravitational waves for a long time. These waves squeeze and stretch anything in their path as they pass by.Ī gravitational wave is an invisible (yet incredibly fast) ripple in space.
