A new analysis finds that gravity obeys Newton’s inverse square law over hundreds of millions of light years, even when tested using 300,000 galaxies. This result leaves little room for alternatives that weaken gravity over long distances. It also sharpens the case for invisible masses that shape the motion of the universe. beyond the distance … Read more
Black holes are one of the most extreme objects in the universe. It can propel matter outward at near-light speeds in powerful plasma beams known as jets. These jets are thought to be one of the most energetic phenomena in the universe. Our new work was published today natural astronomychallenges this intuition. It turns out … Read more
Researchers have taken a major step toward understanding how black holes affect the universe by directly measuring the power of their jets. A team led by Curtin University used a network of radio telescopes spread across the world to take detailed images that reveal just how energetic these jets are. The discovery supports long-standing theories … Read more
