U.S. astrophysicists find ripples from Big Bang (ANSA) - Rome, March 17 - A US team of astrophysicists on Monday confirmed they have detected so-called primordial gravitational waves, or an echo of the Big Bang with which the universe is thought to have come into existence 14 billion years ago.

The Nobel-worthy breakthrough was announced at the Harvard-Smithsonian Center for Astrophysics by an American team using a specialized telescope called BICEP (Background Imaging of Cosmic Extragalactic Polarization) at the Amundsen-Scott South Pole Station to scan the sky at microwave frequencies in search of ripples from the Big Bang.

The aim has been to try to find a residual marker for so-called cosmic inflation, meaning that the cosmos experienced an extremely rapid expansion in its first trillionth of a second of being.

The discovery of these primordial gravitational waves, which Big Bang theorists have been seeking for decades, could offer scientists their first glimpse into how the universe was born.
