    4 giorni fa · 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.

    4 giorni fa · Image credit: NASA. Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
