On 17 March 2014, astronomers have announced the detection of B-mode polarization in the Cosmic Microwave Background. According to inflation models, primordial gravitational waves generated at the very beginning of the universe have imprinted a special signature, B-mode polarization, in the CMB. Gravitational waves, which are important inferences drawn from general relativity, have not been detected directly hitherto. Discovery of B-mode polarization is the strongest evidence that supports the existence of gravitational waves. It is a smoking gun for the Big Bang and inflation and will cast profound influences on cosmology. |
