It is tremendous to be able to calculate what to look for... http://www.sciencealert.com/physicists-calculate-long-lost-signals-emitted-fractions-of-a-second-after-the-big-bang
For the first time, theoretical physicists have calculated the precise frequency of specific gravitational wave signals that would have emerged fractions of a second after the Big Bang.
Just like we had to figure out the frequency of the Higgs boson before scientists could detect it, this means scientists can now start to track down the signals of long-lost cosmological phenomena called 'oscillons', allowing us to peer back further into the Universe than ever before.
