Major discovery bolsters Big Bang theory.

Washington, March18 (Petra)-Waves of gravity that rippled through space right after the Big Bang have been detected for the first time, in a landmark discovery that adds to our understanding of how the universe was born, US scientists said Monday.

The first direct evidence of cosmic inflation -- a theory that the universe expanded by 100 trillion trillion times in barely the blink of an eye -- was announced by experts at the Harvard-Smithsonian Center for Astrophysics.

The detection was made with the help of a telescope called BICEP2, stationed at the South Pole, that measures the oldest light in the universe

If confirmed by other experts, some said the work could be a contender for the Nobel Prize.

The waves that move through space and time have been described as the "first tremors of the Big Bang."

John Kovac, leader of the BICEP2 collaboration at the Harvard-Smithsonian Center for Astrophysics, said years of observations using the telescope at the South Pole preceded Monday's announcement.

"Detecting this signal is one of the most important goals in cosmology today. A lot of work by a lot of people has led up to this point."

The detection confirms an integral connection between Einstein's theory of general relativity and the stranger conceptual realm of quantum mechanics.

The telescope targeted a specific area of sky known as the "Southern Hole" outside the galaxy where there is little dust or extra galactic material to interfere with what humans could see with the potent sky-peering tool.

By observing the cosmic microwave background, or a faint glow left over from the Big Bang, small fluctuations gave scientists new clues about the conditions in the early universe.
