Dark Matter May Replace Black Hole at the Milky Way's Core, Astronomers Suggest New Astronomical Research Challenges Long-Held Assumptions about Sagittarius A* Astronomers suggest that the heart of the Milky Way may not host a supermassive black hole, but instead a vast concentration of enigmatic dark matter producing an equivalent gravitational pull. They argue that this unseen material — believed to account for most of the universe's mass — can explain both the intense motions of stars just light-hours from the galactic center and the smoother, large-scale rotation of matter across the Milky Way's outer regions. The findings were published yesterday in Monthly Notices of the Royal Astronomical Society . Rethinking the Milky Way's Dark Heart The findings challenge the prevailing view that Sagittarius A* (Sgr A*) , the proposed black hole at the center of our galaxy, governs the motion of the so-called S-stars — stellar objects that race around the core at staggering ...

Impossible Neutrino Detected: Scientists Link 2023 Cosmic Shock to Exploding Primordial Black Holes A baffling cosmic event in 2023 saw a neutrino slam into Earth with an energy level that defied all known physics . The particle was vastly more powerful than anything humanity has ever generated, dwarfing even the Large Hadron Collider's capabilities by a factor of 100,000 . Researchers at the University of Massachusetts Amherst now believe such an event could occur when a rare, early-universe black hole — described as quasi-extremal , undergoes a catastrophic explosion . Their findings, reported in Physical Review Letters , not only solve the mystery of the impossible neutrino but also position it as a potential key to understanding the universe at its most fundamental level . From Stellar Collapse to the Early Universe Black holes are no longer the stuff of speculation and scientists have a solid grasp of how they form. When a massive ageing star exhausts its nuclear fuel, ...
