Searching for Gravitational Waves with Pulsars
Pulsars, rapidly spinning neutron remnants, offer a exceptional method for finding gravitational waves. Unlike standard ground-based detectors, which rely on incredibly precise laser interferometry, pulsar timing arrays examine subtle variations in the timing of radio pulses. Each Continue pulsar transmits a highly consistent signal, acting as a cosmic chronometer. A passing gravitational wave would slightly stretch geometry, causing tiny shifts in the pulse receipt. These slight changes, when summed across a broad array of pulsars, can, in theory, reveal the detection of a background gravitational wave signal, possibly originating from supermassive black void fusions.
