Evidence of Cosmic Inflation

"The swirly B-mode pattern is a unique signature of gravitational waves because of their handedness. This is the first direct image of gravitational waves across the primordial sky," said co-leader Chao-Lin Kuo (Stanford/SLAC).  Credit: Keck, NASA, JPL, Harvard CfA et.al

The Big Bang, the (not so aptly named) inflationary event that began the universe we know, has until now been theory.

The researchers took great care to be sure they were not missing something so now  I’m  trying to wrap my head around this and the implications for what is yet to come.

From NASA’s press release:

Astronomers are announcing today that they have acquired the first direct evidence that gravitational waves rippled through our infant universe during an explosive period of growth called inflation. This is the strongest confirmation yet of cosmic inflation theories, which say the universe expanded by 100 trillion trillion times, in less than the blink of an eye.
The findings were made with the help of NASA-developed detector technology on the BICEP2 telescope at the South Pole, in collaboration with the National Science Foundation.
“Operating the latest detectors in ground-based and balloon-borne experiments allows us to mature these technologies for space missions and, in the process, make discoveries about the universe,” said Paul Hertz, NASA’s Astrophysics Division director in Washington.
