Big Bang Gravitational Waves Discovered [News]
posted March 20 2014 4:35.04 by spic0m




Astronomers have found the first direct evidence of cosmic inflation, the theorized dramatic expansion of the universe that put the "bang" in the Big Bang 13.8 billion years ago, new research suggests.

If it holds up, the landmark discovery - which also confirms the existence of hypothesized ripples in space-time known as gravitational waves - would give researchers a much better understanding of the Big Bang and its immediate aftermath.

"If it is confirmed, then it would be the most important discovery since the discovery, I think, that the expansion of the universe is accelerating," Harvard astronomer Avi Loeb, who is not a member of the study team, told Space.com, comparing the finding to a 1998 observation that opened the window on mysterious dark energy and won three researchers the 2011 Nobel Prize in physics.

A team led by John Kovac, of the Harvard-Smithsonian Center for Astrophysics, is announced the discovery at March 17, unveiling results that have been submitted to the prestigious journal Nature.
