Researchers have found signs of gravitational waves or ripples in the fabric of space-time, raising hopes that the findings would help gain insight into 'complete theory of cosmos'. With the help of BICEP2 telescope, researchers claimed to have a discovered a swirly polarization pattern, called B-mode polarization, in the faint light left over from the Big Bang.

Researchers said that gravitational waves have left or right skewed polarization and leave a patterned imprint in space when they travel.

They declared the findings support the evidence for the long-term inflation theory, predicted by American physicist Alan Guth in 1980. Alan termed the theory of inflation as the 'bang' of the Big Bang, which states that the initial expansion of the universe was caused by a repulsive form of gravity. The evidence states that universe started to expand just 10-32 seconds after the Big Bang about 13.7 billion years ago.

Researchers said the discovery of waves also support the theory of general relativity proposed by Albert Einstein. Alan Duffy, astrophysicist at the Swinburne University of Technology, said these space-time ripples are similar to light waves being ripples in the electromagnetic field.

Dr. Duffy said the use of laser inter-ferometry technique, LIGO experiment, will surely help to determine gravitational waves arising from major galactic events near the Milky Way. Karl Glazebrook, Swinburne University astrophysicist, said that inflation also supports the reason for smooth and flat universe.
