It will be very interesting to see if this results stands the test of time. Pretty amazing that we can actually draw conclusions about the universe at a very very early time, which have implications on our understanding of nature today.
Scientists have heralded a "whole new era" in physics with the detection of "primordial gravitational waves" – the first tremors of the big bang. The minuscule ripples in space-time are the last prediction of Albert Einstein's 1916 general theory of relativity to be verified. Until now, there has only been circumstantial evidence of their existence. The discovery also provides a deep connection between general relativity and quantum mechanics, another central pillar of physics.
