Astronomers discover echoes from expansion after Big Bang. Big Bang theory adds evidence for universe's early growth spurt There's no way for us to know exactly what happened some 13.8 billion years ago, when our universe burst onto the scene. But scientists announced Monday a breakthrough in understanding how our world as we know it came to be. If the discovery holds up to scrutiny, it's evidence of how the universe rapidly expanded less than a trillionth of a second after the Big Bang. "It teaches us something crucial about how our universe began," said Sean Carroll, a physicist at California Institute of Technology, who was not involved in the study. "It's an amazing achievement that we humans, doing science systematically for just a few hundred years, can extend our understanding that far." What's more, researchers discovered direct evidence for the first time of what Albert Einstein predicted in his general theory of relativity: Gravitational waves. In the beginning, the universe got very big very fast, transforming itself in a fraction of an instant from something almost infinitesimally small to something imponderably vast, a cosmos so huge that no one will ever be able to see it all. This is the premise of an idea called cosmic inflation — a powerful twist on the big-bang theory — and Monday it received a major boost from an experiment at the South Pole called BICEP2. A team of astronomers led by John Kovac of the Harvard-Smithsonian Center for Astrophysics announced that it had detected ripples from gravitational waves created in a violent inflationary event at the dawn of time. A vanishingly subtle twist in the orientation of light from the edge of the visible universe has provided the first direct evidence for cosmic inflation -- a fleeting period of exponential growth when the universe was only a tiny fraction of a second old. Cosmic inflation Big Bang breakthrough: Scientists discover gravitational waves ...march 2014. The discovery predicted by Albert Einstein nearly a century ago would be the final piece in one of the greatest achievements of the human intellect: an understanding of how the universe began and evolved. The 10-meter South Pole Telescope and the BICEP Telescope, which detected the gravitational waves, are seen against the night sky's Milky Way at Amundsen-Scott South Pole Station. Astronomers announced on Monday that they had discovered what many consider the holy grail of their field: ripples in the fabric of space-time that are echoes of the massive expansion of the universe that took place just after the Big Bang. Predicted by Albert Einstein nearly a century ago, the discovery of gravitational waves would be the final piece in one of the greatest achievements of the human intellect: an understanding of how the universe began and evolved into the cornucopia of galaxies and stars, nebulae and vast stretches of nearly empty space that constitute the known universe. "Detecting this signal is one of the most important goals in cosmology today," John Kovac of the Harvard-Smithsonian Center for Astrophysics, who led the research, said in a statement.

March 18 (Bloomberg) -- Ripples in ancient light form the first direct evidence of the Big Bang, the original expansion of the universe from a tiny compressed mass that gave birth to the present vastness of the cosmos, scientists said. Waves from the initial expansion still exist in cosmic background microwaves, a form of light that remains from the universe's earliest days, a team from institutions including Harvard-Smithsonian Center for Astrophysics, Stanford University and the
