ResumoThe geometry of the universe is Euclidean and space is flat. This has now been confirmed from detailed measurements of the cosmic microwave background – the radiation left over from the big bang – by an international team of astronomers from Italy the UK, the US, Canada and France. The Boomerang collaboration, led jointly by Paolo de Bernardis of the University of Rome and Andrew Lange of the California Institute of Technology has measured the angular distribution of temperature fluctuations in the microwave background with unprecedented accuracy Such fluctuations contain information about the energy density and curvature of the universe (P de Bernardis et al. 2000.Nature 404 955).
