A new crew of potential ripples in spacetime has just debuted — emphasis on the word “potential.”
By loosening the criteria for what qualifies as evidence for gravitational waves, physicists identified 1,201 possible tremors. Most are probably fakes, spurious jitters in the data that can mimic the cosmic vibrations, the team reports August 2 at arXiv.org. But by allowing in more false alarms, the new tally may also include some weak but genuine signals that would otherwise be missed, potentially revealing exciting new information about the sources of gravitational waves.
Scientists can now look for signs that may corroborate some of the uncertain detections, such as flashes of light
