THE curtain at the edge of the universe may be rippling, hinting that there?s more backstage. Data from the European Space Agency?s Planck telescope could be giving us our first glimpse of another universe, with different physics, bumping up against our own.
That?s the tentative conclusion of an analysis by Ranga-Ram Chary, a researcher at Planck?s US data centre in California. Armed with Planck?s painstaking map of the cosmic microwave background (CMB) ? light lingering from the hot, soupy state of the early universe ? Chary revealed an eerie glow that could be due to matter from a neighbouring universe leaking into ours.
