YOUR GOAL
Master of Ripples in spacetime
Cosmic power output: For a tiny fraction of a second, the collision of the first two detected black holes released more energy than all the stars in the universe combined.
A ripple in the fabric of spacetime caused by the acceleration of massive cosmic objects. On September 14, 2015, LIGO detectors first recorded these ripples, which originated from merging black holes.
