I read with great excitement that Alan Guth's theorectical prediction of the inflationary universe has been validated by the indirect detection of gravitational waves via the special polarisation of the cosmic microwave radiation (CMR). Gravitational waves are predicted in Einstein theory of General Relativity as the stuff that ruffles space-time. This discovery is a step forward to validate the Big Bang theory of the observable universe.
Well we live I exciting times. Previously we got confirmation of the Higgs Boson and now cosmic inflation. What else is coming.
I will probably reread Alan Guth's book on the "the Inflationary Universe" when I get the time.
