St. Patrick's Day 2014 Begorrah! Gravitational Waves from Big Bang Detected! A curved signature in the cosmic microwave background light provides proof of inflation and spacetime ripples! A Game Changing Discovery if verified by further examination of this incredible new data set. http://www.scientificamerican.com/article/gravity-waves-cmb-b-mode-polarization/?utm_content=buffer41edf&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer
The bottom part of this illustration shows the scale of the universe versus time. Specific events are shown such as the formation of neutral Hydrogen at 380 000 years after the big bang. Prior to this time, the constant interaction between matter (electrons) and light (photons) made the universe opaque. After this time, the photons we now call the CMB started streaming freely.
Stephen Hawking has claimed victory in a bet with a fellow scientist over the discovery of primordial gravitational waves, ripples in the structure of space-time from the birth of the universe. The Cambridge cosmologist bet Neil Turok, director of the Perimeter Institute in Canada, that gravitational waves from the first fleeting moments after the big bang would be detected.
