CAPE CANAVERAL, Florida, Apr 5: Closer scrutiny of radiation left over from the creation of the universe shows the Big Bang took place about 13.8 billion years ago, 100 million years earlier than previous estimates, scientists said on Thursday. The findings are among the first results from analysis of data collected by the European Space Agency’s Planck spacecraft, which is providing the most detailed look to date at the remnant microwave radiation that permeates the universe.
