According to a study published in the journal Nature Astronomy, LID-568 is expanding at an unprecedented rate challenging the conventional understanding of black holes.

• Primordial black holes are formed either from the explosion of the universe's initial stars or the collapse of large gas clouds present in the early universe.
• LID-568 appeared to be consuming infalling material due to gravitational attraction known as accretion,  at more than 40 times the Eddington limit.
  • Its rapid growth suggests that significant portion of mass growth can occur during single episode of rapid accretion; it could explain formation of supermassive black holes early in universe. 

About Eddington limit

• It is a theoretical limit for the maximum energy output the black hole can produce through the accretion process.
• It assumes that the outward force from the radiation produced during the accretion process balances the gravity of the infalling material.

About LID-568:   

• It is a supermassive black hole formed about 1.5 billion years after the Big Bang event.
• It has a mass about 10 million times greater than the sun, so 2-1/2 times that of Sagittarius A*.
  • Sagittarius A*is a supermassive black hole located at the center of our galaxy-the Milky Way.
