It’s a big day for science: Big Bang inflation theory gets some strong evidence…..

Story from Nature here. This is the notion (now supported with good evidence) that in the fraction of a second following the Big Bang, the universe expanded exponentially (inflation). The evidence for that inflation comes from looking for perturbations in the polarization of the  cosmic microwave background that themselves are evidence for gravitational waves. If it holds up, it’ll be an easy Nobel choice.
