Supermassive black holes may unleash winds 100 times more powerful than expected, spreading energy across hundreds of thousands of light-years. Date: September 15, 2026 Source: Tohoku University Summary: Astronomers have discovered that winds from a supermassive black hole are about 100 times more powerful than previously thought. XRISM observations showed the resulting turbulence spreading roughly 300,000 light-years, extending far beyond the black hole’s host galaxy. The energy involved rivals several billion supernova explosions, revealing just how dramatically black holes can influence the space around them.
Maybe black holes also eject Le Sage particles, and then we live in a 'sea' of black holes, where grsvity is simply the effect of the Le Sage particles.
