Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe
They reported Wednesday that they were able to “hear” what are called low-frequency gravitational waves — changes in the fabric of the universe that are created by huge objects moving around and colliding in space.
In the latest research, scientists were searching for waves at much lower frequencies. These slow ripples can take years or even decades to cycle up and down, and probably come from some of the biggest objects in our universe: supermassive black holes billions of times the mass of our sun. “Supermassive black hole binaries, slowly and calmly orbiting each other, are the tenors and bass of the cosmic opera,” Marka said.
The scientists pointed telescopes at dead stars called pulsars, which send out flashes of radio waves as they spin around in space like lighthouses. The NANOGrav team monitored 68 pulsars across the sky using the Green Bank Telescope in West Virginia, the Arecibo telescope in Puerto Rico and the Very Large Array in New Mexico. Other teams found similar evidence from dozens of other pulsars, monitored with telescopes across the globe.
