Gravitational waves make a ripple before peer review

Earlier this week, the discovery of gravitational waves by scientists working with the BICEP2 collaboration at the south pole made a huge impact in the media.

The discovery – the first ever glimpse of gravitational waves, ripples in spacetime predicted by Einstein, allows us to look back  in time further than it was thought possible. It teaches us something fundamentally new about what happened a trillionth of a trillionth of a trillionth of a second after the big bang, and it could mean the beginning of a whole new era of astrophysics.
