Q&A: Astrophysicist explains how black hole mergers and quasars help detect gravitational wave networks
Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses arrive early. When space/time is stretched, the pulses arrive late. The overall stretch and squash is about 1 part in a million billion—or the size of a virus divided by the diameter of the Earth. Very small!

Black holes: Facts about the darkest objects in the universeBlack holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being empty, black holes are chock full of matter that gets squeezed into a teensy space.
