    Fast radio bursts could help solve the mystery of the universe’s expansion

    Astronomers used fast radio bursts for the first time to measure the Hubble constant in hopes of ending the debate on the universe’s expansion rate.

  7. Cosmology

    Physicists’ devotion to symmetry has led them astray before

    If dark matter WIMPs are mythical, they join the ancient idea that the planets moved in circles.
