Searching for Gravitational Waves with Pulsars
Pulsars, rapidly whirling neutron objects, offer a distinctive method for detecting gravitational disturbances. Unlike traditional ground-based detectors, which rely on incredibly precise laser interferometry, pulsar timing networks analyze subtle variations in the arrival of radio pulses. Each pulsar transmits a highly consistent signal, acting as a cosmic chronometer. A passing gravitational ripple would slightly stretch spacetime, causing tiny shifts in the pulse arrival. These slight changes, when combined across a extensive array of pulsars, can, in theory, reveal the detection of a residual gravitational wave signal, possibly originating from supermassive black singularity fusions.
