Astronomers with the Event Horizon Telescope (EHT) made history in 2019 by producing the first image of a black hole. The object in question was the supermassive black hole (SMBH) at the center of M87, a supergiant elliptical galaxy about 53.5 million light-years distant in the constellation Virgo. This was followed in 2022 with the first-ever image of Sagittarius A*, …

A team of South Korean researchers has delivered experimental proof of “multi-scale coupling” in plasma, demonstrating how microscopic events can lead to big changes in this state of matter, Interesting Engineering reported. The experiment seeks to explain how kinetic turbulence at the particle scale affects an entire plasma system, which has long been a challenge in plasma physics. The results …

Scientists just measured something that sounds impossible. When light passes through atoms, it can spend what appears to be less than zero time interacting with them. Yes, negative time. And no, this isn’t science fiction. Picture a stadium crowd doing the wave. People stand and sit in sequence, but somehow the wave moves faster than any single person. …

An image based on numerical simulations of a black hole merger – credit, NASA/Ames Research CenterC. Henze A collaboration between humanity’s three gravitational wave detectors have identified a black hole merger event that created something 225-times the size of our Sun. It’s the largest such event ever detected in the history of gravitational wave astronomy, and pushed the limits of …
