Searching for Gravitational Waves with Pulsars
Pulsars, rapidly whirling neutron stars, offer a unique method for finding gravitational waves. Unlike standard ground-based apparatuses, which depend on incredibly sensitive laser interferometry, pulsar timing arrays examine subtle variations in the arrival of radio pulses. Each pulsar radiates a highly regular signal, acting as a cosmic clock. A passing gravitational distortion would slightly warp space, causing tiny alterations in the pulse timing. These tiny changes, when averaged across a broad array of pulsars, can, in principle, reveal the detection of a residual gravitational disturbance signal, potentially originating from supermassive black void fusions.
