The newborn universe supposedly expanded faster than the speed of light. That bizarre, hypothetical stretching should have set off ripples in space and time called gravitational waves, which 13.7 billion years later should have left traces in the afterglow of the big bang, the cosmic microwave background. The 400 researchers working with the European Space Agency’s Planck satellite hope to spot those traces–subtle patterns in the polarization of the microwaves called “B modes”–before anyone else does.
