  • Gravitational-wave and electromagnetic observations of neutron-star-black-hole mergers can provide precise local measurements of the Universe's rate of expansion.
  • In new research, astrophysicists from Sweden, the United Kingdom and the Netherlands simulated over 25,000 such mergers, aiming to see how many would likely be detected by instruments on Earth.
  • "The current expansion rate of the Universe.
