Searching for Gravitational Waves with Pulsars
Pulsars, rapidly whirling neutron stars, offer a distinctive method for observing gravitational waves. Unlike standard ground-based apparatuses, which depend on incredibly precise laser interferometry, pulsar timing arrays analyze subtle fluctuations in the occurrence of radio pulses. Each pulsar emits a highly regular signal, acting as a cosmic timer. A passing gravitational wave would slightly stretch space, causing tiny shifts in the pulse timing. These tiny changes, when summed across a extensive array of pulsars, can, in principle, reveal the presence of a ambient gravitational wave signal, potentially originating from giant black void collisions.
