Description
Gravitational waves from black holes and neutron stars are standard candles, the only input needed to infer their luminosity distance being Einstein's general theory of relativity. Combined with follow-up electromagnetic observations to measure the redshift of their hosts will provide a precision tool for calibration-free cosmology. Over the next decade we can expect the current generation of LIGO and Virgo detectors and their upgrades to resolve the Hubble tension. Future observatories such as the Cosmic Explorer will help determine the nature of dark energy.
