"Indeed, several experiments will collect data within the next few years to clarify the situation in great detail. We should expect to know fairly soon if there is a gravitational wave signal from the Big Bang, a ringing in the structure of space itself from an ultrafast expansion that lasted for fractions of a second, as if the cosmos was in a hurry to grow up. Whatever the verdict, waves or no waves, the news will be key to our understanding of the early universe." - Todd Hoff
