SYDNEY - Scientists say they have discovered a black hole so big that it challenges the theory about how they grow.
Scientists said this black hole was formed about 900 million years after the Big Bang.
But with measurements indicating it is 12 billion times the size of the Sun, the black hole challenges a widely accepted hypothesis of growth rates.
"Based on previous research, this is the largest black hole found for that period of time," Dr. Fuyan Bian, Research School of Astronomy and Astrophysics, Australian National University (ANU), told Reuters on Wednesday.
"Current theory is for a limit to how fast a black hole can grow, but this black hole is too large for that theory."
The creation of supermassive black holes remains an open topic of research. However, many scientists have long believed the growth rate of black holes was limited.
Black holes grow, scientific theory suggests, as they absorb mass. However, as mass is absorbed, it will be heated creating radiation pressure, which pushes the mass away from the black hole.
"Basically, you have two forces balanced together which sets up a limit for growth, which is much smaller than what we found," said Bian.
The black hole was discovered by a team of global scientists led by Xue-Bing Wu at Peking University, China, as part of the Sloan Digital Sky Survey, which provided imagery data of 35% of the northern hemisphere sky.
The ANU is leading a comparable project, known as SkyMapper, to carry out observations of the Southern Hemisphere sky.
Bian expects more black holes to be observed as the project advances.

Pin prick compared to the void the universe will be so large matter cannot find each other so no new stars are born and then that expansion goes on for some time, all in the dark, like a black hole is.

Sort of along the same line but if this turns out to be valid and useful in predicting weather pattern changes do 'we' get a refund for all the false leads we have been sold up until now?

A new study claims that volcanic eruptions along the ocean floor may impact earth’s climate cycle and that predictive models, including those that analyze humanity’s impact on climate change, may need to be modified.
“People have ignored seafloor volcanoes on the idea that their influence is small—but that’s because they are assumed to be in a steady state, which they’re not,” said Maya Tolstoy, a geophysicist and author of the study that appeared in Geophysical Research Letters and was also reported on in Science Daily.
Until now, scientists presumed that seafloor volcanoes exuded lava at a slow and steady pace, but Tolstoy thinks that not only do the volcanoes erupt in bursts, they follow remarkably consistent patterns that range anywhere from two weeks to 100,000 years.
