A recent study conducted at Northwestern University indicates that black holes devour their environment at a considerably swifter pace than previously thought.
Some of this matter might fall directly into the black hole and become ingested, while other pieces might be expelled as high-energy jets along the rotational axis of the black hole.
“But some quasars — which result from black holes eating gas from their accretion disks — appear to drastically change over time scales of months to years. This variation is so drastic. It looks like the inner part of the disk — where most of the light comes from — gets destroyed and then replenished. Classical accretion disk theory cannot explain this drastic variation. But the phenomena we see in our simulations potentially could explain this.

Black holes eat faster than previously expectedWhile previous researchers have hypothesized that black holes eat slowly, new simulations indicate that black holes scarf food much faster than conventional understanding suggests. Some quasars brighten and disappear within months -- a time scale that aligns with the new findings.
