Searching for Gravitational Waves with Pulsars
Pulsars, rapidly whirling neutron remnants, offer a unique method for observing gravitational disturbances. Unlike conventional ground-based detectors, which rely on incredibly precise laser interferometry, pulsar timing constellations examine subtle fluctuations in the occurrence of radio pulses. Each pulsar radiates a highly periodic signal, acting as a cosmic clock. A passing gravitational wave would slightly stretch spacetime, causing tiny delays in the pulse arrival. These tiny changes, when combined across a large array of pulsars, can, in theory, reveal the detection of a residual gravitational ripple signal, maybe originating from giant black hole fusions.
