If LIGO regularly registers gravitational waves, it will more than vindicate Einstein. The observatory may help answer pressing questions about the cosmos’s biggest mysteries, among them black holes, dark matter, and the Big Bang.
Anything with an accelerating mass has a gravitational effect — an atomic bomb, a spinning aircraft carrier, even you. Learn more about these ripples in space and how LIGO is designed to capture the biggest gravitational waves.
LIGO, or the Laser Interferometer Gravitational-wave Observatory, is just one of five large-scale gravitational-wave detectors in the world. Find out how they rely on each other to achieve their goals.
Our eyes can only detect a fraction of light in the electromagnetic spectrum — otherwise we’d see gamma-ray bursts, flashes that outshine the sun by a million trillion times, about once a day. Learn more.
In early 2004, two unlikely explorers traveled to the red planet and found strong evidence to confirm water once existed on the surface of Mars, and in sufficient quantity to possibly have harbored life.
