"Neutron Star Collisions: A Key to Measuring Universe Expansion"

Astrophysicists from the Niels Bohr Institute have proposed a novel method for measuring the expansion of the universe by observing colliding neutron stars, known as kilonovae. The researchers argue that this method can help resolve the discrepancy between measurements of the Hubble Constant obtained through supernovae and the Cosmic Microwave Background (CMB). By measuring the distance to kilonovae and comparing their luminosity to the light received on Earth, astronomers can calculate the Hubble Constant without the need for calibration or correction factors. While more examples are needed to establish a robust result, this method shows promise in providing consistent measurements of cosmic expansion.
