How does an experiment at LIGO actually work?
Thursday, February 11, 2016 - 08:50
in Astronomy & Space
Gravitational waves are mysterious ripples in the fabric of space and time that travel across our universe at the speed of light. Predicted by Einstein exactly 100 years ago, a number of experiments have been searching for them. One of these experiments, LIGO, has been the focus of much speculation. But how does it actually work and how reliable is it?
