Ripples in the fabric of space-time
Simulation
Gravitational waves are prediction of the Theory of General Relativity
Their existence has been inferred by science but only now directly detected
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
Detecting the waves opens up the Universe to completely new investigations
