black holes grow alongside their host galaxies in the early universe?
Scientists previously thought that
black holes grow by picking up mass from the environment around them.

But recent finds are challenging even those theories and may force astronomers to rethink how
these black holes grow.

black holes grow fractal skins as they feed «-RRB- also exhibit such fractal behaviour.
Black holes grow in mass as they continue to devour their surrounding matter.
Other models of how these ancient behemoths evolved, including one in which
black holes grow by merging with millions of smaller black holes and stars, await further testing.
The observations, the best yet, strongly support the idea that galaxies and their central
black holes grow together, says Karl Gebhardt of the University of Texas in Austin.
In terms of mass they lie between the more commonly found stellar - mass and supermassive types of black hole [3], and could tell us about how
black holes grow and evolve within clusters like Messier 15, and within galaxies.
Black holes grow by consuming material that passes too close to their enormous gravity wells.
The existence of middleweights could explain how
black holes grow from small to supermassive.

black holes grow and evolve.
«These systems can devour vast quantities of matter due to their extreme gravitational pull, making
the black holes grow.
As Britain's energy
black hole grows larger, has anyone in government got a grip on what we're doing about it?
Alternative explanations posit these anomalously massive
black holes grew and merged in throngs of stars called globular clusters, but that process can easily require more time than the current age of the universe.
These gas - filled limbs are often where new stars form, and can constrain how big a galaxy's central
black hole grows.
The amplitude and frequency of these waves could reveal the initial mass of the seeds from which the first
black holes grew since they were formed 13 billion years ago and provide further clues about what caused them and where they formed, the researchers said.
Scientists aren't sure how
black holes grew so big so early.
The findings have scientists puzzling over how early
black holes grew into the supermassive beasts they are today without a steady diet of gas, dust, stars, and other fodder.
As a result, the team reports online this week in The Astrophysical Journal Letters, the earliest
black holes grew less than 1 % over 200 million years.
Likewise, if
a black hole grows large enough to intersect a parallel three - dimensional universe in the extra dimensions, its decay properties would suddenly change.
One possibility is that seed
black holes grew out of the demise of the earliest stars; another explanation is that gaseous pre-galactic disks gravitationally collapsed to create nascent black holes.
Some astronomers have suggested that they formed suddenly out of collapsing gas clouds, but most suspect that the supermassive
black holes grew after their initial formation.
In the early universe, when gas was abundant, a handful of voracious
black holes grew to become extremely massive by swallowing it up, emitting immense amounts of energy.
As the galaxy forms stars and increases its mass in a constant and substantial manner,
its black hole grows as well, and does so at an even faster rate,» explains Mancuso.
Entropy grows at the same rate as the surface area of the superfluid helium, instead of its volume — mimicking how the entropy of
a black hole grows as it gobbles up matter and expands.
«That means
this black hole grew much more efficiently than its galaxy — contradicting the models that predicted a hand - in - hand development,» he said.
Because of this remarkable disparity, the team deduced
this black hole grew so quickly the host galaxy was not able to keep pace, calling into question previous thinking on the co-evolution of galaxies and their central black holes.
Artist's impression of the heart of a quasar, at which a supermassive
black hole grows as it accretes material.
Or could this provide us with insight into how all supermassive
black holes grew in the early universe?
This is the most distant quasar — a supermassive black hole surrounded by a disk of gas — ever identified and it will help astronomers to better understand exactly how
black holes grew when the universe was first forming.
Using data from the image, researchers found that
these black holes grew in bursts, rather than by slowly accumulating matter, about one to two billion years after the Big Bang.

@pattic: I

blackest, butt
hole of rage, anger and despair I have ever experienced.
Do you know that just recently, some evolutionary biologists discovered that some species
grow younger with age, which is contradictory to the Evolutionary Theory, and that our Solar System has no
Black Holes, which is contradictory to the Big Bang Theory?
Measurements of the water vapor and of other molecules, such as carbon monoxide, suggest there is enough gas to feed the
black hole until it
grows to about six times its size.
Mr Hammond now wants to target contractors - including IT workers and management consultants - to fill a
growing black hole in Treasury coffers.
Stephen Hawking, a
black hole whisperer who divined the secrets of the universe's most inscrutable objects, left a legacy of cosmological puzzles sparked by his work, and inspired a generation of scientists who
grew up reading his books.
As an explanation for the first quasars, each of these pathways for the formation of
black hole seeds has the same problem: the seeds would have to
grow extraordinarily quickly within the first billion years of cosmic history to create the earliest quasars.
To
grow to 109 solar masses, a
black hole seed of 10 solar masses would have to gobble stars and gas unimpeded at the Eddington rate for a billion years.
What's more, when matter falls into a
black hole, the area of its event horizon
grows.
Primordial
black holes could have coalesced from tiny fluctuations in the density of the universe and then
grown as the universe expanded.
Considering we are seeing this giant
black hole's activity from a time when the universe was only a tenth of its present age, astronomers are puzzled about how it could've
grown so big so fast.
But if you have clusters of
black holes at the centers of galaxies, there are mechanisms by which some could rapidly
grow, form binaries and merge with each other.»
In effect, if the first quasars
grew from Population III
black hole seeds, they would have had to eat faster than the Eddington rate.
Black holes also
grew in the simulation, feeding on the gas around them, and releasing energy into the wider galaxy.
After the galaxy hosting the DCBH merges with its parent galaxy, however, the mass of the
growing black hole will briefly exceed that of the stars.
