Gravitational waves are a prediction of the Theory of General Relativity It took decades to develop the technology to directly detect them They are ripples in the fabric of space and time produced by violent events Accelerating masses will produce waves that propagate at the speed of light Detectable sources ought to include merging black holes and neutron stars LIGO fires lasers into long, L-shaped tunnels; the waves disturb the light
