It also confirms more than any other evidence that the universe had a beginning and expanded at a rate faster than the speed of light within less than a trillion of a trillion of a trillion of a second — less than 10 ^ -35 of a second — of the Big Bang by detecting the miniscule «light polarizations» called B - Modes caused by the Gravitational Waves — which were theorized in 1916 by Albert Einstein in his Theory of General Relativity but never detected before — of the Inflation of the Big Bang which are embedded in the Cosmic Microwave Background Radiation — CMB or CMBR that was discovered by American scientists back in 1964.

Inflation is not the first set of theories to predict gravity waves or an epicenter to the universe either, so not much has changed on that front except that we can now make models which reflect these waveforms and weed out disagreeing models.
