No Traces of "Knots" in Space... Yet

  Theories of the primordial Universe predict the existence of knots in the fabric of space – known as cosmic textures – which could be identified by looking at light from the cosmic microwave background (CMB), the relic radiation left over from the Big Bang. Using data from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) satellite, researchers [continue reading]

New Cosmological Insights from the South Pole Telescope

Analysis of data from the 10-meter South Pole Telescope (SPT) is providing new support for the most widely accepted explanation of dark energy – the mysterious force that is responsible for the accelerating expansion of the universe. The data strongly support Einstein’s cosmological constant, even though the analysis was based on only a fraction of [continue reading]

The Beginning of Dark Energy

The Sloan Digital Sky Survey (SDSS-III) today announced the most accurate measurements yet of the distances to galaxies in the faraway universe, giving an unprecedented look at the time when the universe first began to expand at an ever-increasing rate. Scientists from the University of Portsmouth and the Max-Planck Institute for Extraterrestrial Physics presented the [continue reading]
