Researchers using different techniques to measure how fast the universe is expanding have come up with two different answers, a conflict that so far has resisted explanation. Researchers at the Massachusetts Institute of Technology say the conflict may be resolved by analysis of gravitational waves from neutron star-black hole mergers, resulting in a value for the Hubble constant, a measure of the Universe’s expansion, that is more precise than earlier results.
