black hole feeds at 40 times the theoretical limit
Briefly

Finding supermassive black holes in the early universe conflicts with existing theories about their growth. They shouldn't have existed so soon after the Big Bang, yet they do.
The Webb Space Telescope has discovered a black hole capable of feeding at an astonishing rate, significantly exceeding what was previously thought theoretically possible for prolonged periods.
Matter accumulating around a black hole forms an accretion disk, which heats up and emits radiation. This radiation can limit how fast the black hole can grow.
The Eddington Limit is a crucial concept in black hole growth; it dictates the balance between gravitational pull and radiation pressure, influencing the formation of supermassive black holes.
