BICEP2 and gravitational waves in the CMB

From what we can tell from the papers, it looks as if the signature of gravitational waves from the epoch of inflation has been found in the cosmic microwave background. But trying to watch the technical presentations over the net from CfA has been a major exercise in frustration as everyone and his dog tries to look at the same feed.

This is certainly a very modern problem.

What does this result mean? It means there is pretty good evidence for new physics that would drive cosmic inflation. Quite what this physics might be is unclear, but rest assured that every theorist will have several different and mutually contradictory theories explaining this result real soon now.
