What we have to do is take other telescopes and look in that part of the sky, and the simulations are going to tell us what to look for to find a merging black hole.". There are multiple space background sky boxes. Noble, who works at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said these binary systems emit gravitational waves and influence surrounding gases, leading to unique light shows detectable with conventional telescopes. The LIGO Laboratory is supported by the National Science Foundation and operated jointly by Caltech and MIT. "We probably will never find a binary black hole with a telescope until we simulate them to the point we know exactly what we're looking for, because they're so far away, they're so tiny, you're going to see just one speck of light," Schnittman said.
