Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored in a new theoretical study: "When Black Holes Admit Pair-of-pants ...
For nearly a century, physicists have relied on the Born rule to calculate the chances of different outcomes when they measure a quantum system. Yet despite decades of effort, nobody has managed to derive the rule from more ...
Unlike classical physics, quantum mechanics generally cannot tell us exactly what will happen in an individual event. Instead, it predicts the probabilities of different outcomes. As one of the theory's early pioneers, Erwin ...
Ahead of the U.N. Climate Change Conference (COP31) meeting in Antalya, Turkiye, held in Nov. 2026, an expert writing in The BMJ's climate issue argues that accurate data on greenhouse gas emissions during armed conflict ...
Glimpses of the "gallium anomaly" were first seen in the mid-1990s, but it was first clearly discovered and stated in 2007 by neutrino physicist Carlo Giunti of Italy. The problem is simple to state but potentially very important: ...
Two thousand years ago, the Arctic remnants of a once-vast ice sheet started to grow again. It was the beginning of a new glacial period, more conversationally known as the next ice age—but by the 1960s, summer temperatures ...
Have you ever binge-watched Bluey or a British crime drama and caught yourself imitating the characters' accents out loud? Rest assured, you are not alone. While it's a common belief that picking up someone else's accent ...
Moderately cold temperatures have proven to effectively extend lifespan and delay age-related decline in animals. However, how cold temperatures trigger these beneficial effects at the molecular level has remained largely ...
For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an electron—into an exquisitely controlled quantum state.
About 20,000 years ago, an enormous, floating ice shelf more than a mile (1.6 kilometers) thick helped lock in three of the largest ice sheets in northern Canada and Greenland. When that ice shelf disappeared, it helped unlock ...
