Astrophysicists at the Harvard-Smithsonian Center have observed gravitational waves -- the first ever direct evidence of the Big Bang, the theory that the entire universe sprung into existence from a tiny spot in the universe 13.8 billion years ago. The significance of this discovery is comparable in importance to CERN's confirmation of the Higgs boson in 2012, and there is already talk of a Nobel prize for Harvard's new findings.
