The waves are passing by several pulsars and the Earth (on the right)...Scientists have found evidence of ripples in the very fabric of space-time itself..The motion of black holes and other massive objects through space can create ripples in the fabric of the universe, called gravitational waves. On Wednesday (28 June 2023) researchers announced the first evidence of a background of such long-wavelength gravitational waves in the cosmos. These waves are thought to have been created over eons by supermassive black holes, up to billions of times the mass of our Sun, circling each other before they merge. .The background ripples detected by NANOGrav could help scientists better understand how gravitational waves are created and what happens to them as they propagate through the universe. They could also be used to study supermassive black hole mergers - events that can last for millions of years. Scientists think these mergers happen in most galaxies and influence their evolution...The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) presented the evidence in a series of papers published in the Astrophysical Journal Letters. NANOGrav is a National Science Foundation-funded Physics Frontiers Center of more than 190 scientists from the United States and Canada, including scientists at NASAâ??s Jet Propulsion Laboratory in Southern California and other NASA centers. The collaborative project has spent more than 15 years collecting high-precision data from ground-based radio telescopes, looking for these gravitational waves...Gravitational waves were first predicted by Albert Einstein in 1916. They would not be confirmed until 2015, when the (Credit Image: © Cover Images/Zuma Press/Fotoarena)
