Searching for Gravitational Waves with Pulsars
Pulsars, rapidly spinning neutron objects, offer a exceptional method for observing gravitational waves. Unlike conventional ground-based apparatuses, which depend on incredibly precise laser interferometry, pulsar timing networks investigate subtle changes in the timing of radio pulses. Each pulsar radiates a highly consistent signal, acting as a cosmic timer. A passing gravitational wave would slightly stretch space, causing tiny delays in the pulse arrival. These minute changes, when summed across a large array of pulsars, can, in principle, reveal the existence of a background gravitational disturbance signal, maybe originating from supermassive black hole fusions.
