Gravitational Waves Trivia Questions

Gravitational waves are ripples in spacetime itself, not electromagnetic waves. They are produced by mass acceleration, not charged particles.

Gravitational waves propagate at the speed of light in a vacuum, as predicted by general relativity and confirmed by observations.

This quadrupolar distortion is fundamental—LIGO's L-shaped arms detect these tiny length changes as waves pass through Earth.

Gravitational waves interact extremely weakly with matter, passing through planets and stars almost entirely unabsorbed—no ordinary shield works.

LIGO's first detection (GW150914) involved black holes of about 29 and 36 solar masses merging into a 62-solar-mass black hole.

LIGO announced the first direct detection on February 11, 2016, from a 2015 event. Einstein predicted them in 1916.

Rainer Weiss, Barry Barish, and Kip Thorne shared the 2017 Nobel for their leadership in LIGO and the first detection.

Any accelerating mass produces gravitational waves, but they are incredibly weak. Even you jumping creates them, just undetectably tiny.
