This artist’s concept shows stars, black holes, and nebula laid over a grid representing the fabric of space-time. Ripples in this fabric are called gravitational waves. The NANOGrav collaboration detected evidence of gravitational waves created by black holes billions of times the mass of the Sun. Credit: NANOGrav collaboration; Aurore Simonet
