Observational results inconsistent with theory National Radio Astronomy ObservatoryShare Print E-Mail A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that theorists need to revise the “standard model” that describes the fundamental nature of the Universe. The new distance measurements allowed astronomers to refine their calculation…

New method may resolve difficulty in measuring universe’s expansion

News Release 8-Jul-2019 Neutron star mergers can provide new ‘cosmic ruler’ National Radio Astronomy Observatory Astronomers using National Science Foundation (NSF) radio telescopes have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers of pairs of neutron stars into a “cosmic ruler” capable of measuring the expansion…
