Supermassive black holes may have a completely unexpected cosmic delivery service supplying them with gas and S dust to feast on. This could result in the cosmic titans feeding much faster than scientists had expected, gorging themselves over a period of months rather than hundreds or even thousands of years. Supermassive black holes with masses of millions or even billions of times that of the Sun are believed to dwell at the hearts of most galaxies, and when they’re surrounded by vast plates of gas and dust called accretion discs, they power quasars.
These new findings about black hole feeding rates could help shed light
