Monstrously huge black hole devours an Earth-size chunk of matter every second

Astronomers have detected the brightest and fastest-growing black hole to have existed in the last 9 billion years. The enormous cosmic entity is 3 billion times more massive than the sun and swallows up an Earth-size chunk of matter every second.

The new supermassive black hole, known as J1144, is around 500 times as Sagittarius A*, the supermassive black hole at the heart of the Milky Way, which was recently photographed for the first time. A ring of superhot plasma around the enormous void also emits around 7,000 times more light than our entire galaxy.

Australian astronomers discovered the cosmic juggernaut using data from Australian National University's SkyMapper Southern Sky Survey, which aims to map out the entirety of the sky in the Southern Hemisphere. Locating the supermassive black hole was like finding a "very large, unexpected needle in the haystack," the researchers said in a statement(opens in new tab).

"Astronomers have been hunting for objects like this for more than 50 years," lead researcher Christopher Onken, an astronomer at the Australian National University (ANU) in Canberra, said in the statement. "They have found thousands of fainter ones, but this astonishingly bright one had slipped through unnoticed."

The black hole's voracious appetite dwarfs that of other similarly huge supermassive black holes. Normally, the growth rates of these enormous cosmic entities slow down as they become more massive, according to the statement. This is likely due to increased Hawking radiation — thermal radiation that is theorized to be released from black holes due to the effects of quantum mechanics.

So if the gravitation is greater, then wouldn't that mean that the black hole is squished more - and therefore be physically smaller ??

Obviously black holes are made of incompressible stuff. One of the terms I've seen in physics papers is quark fluid, which is described as incompressible.

In any case, it only makes sense that there must be limit to matter density.

"Can the adjectives 'Big' and 'Small' be accurately used to describe black holes?"

The "size" of an african-anerican hole is determined and registered by the diameter of the observable event horizon...
While you are correct that as mass is ingested, it is, apparently, added to the singularity and the distortion of space-time (often referred to as gravity) is, as you said, increased...
In addition, over time in millions of years, we would observe a larger event horizon and say it got bigger...

OTOH, since the singularity is an infinity, it would not get "bigger" since infinity plus the Earth's mass is still infinity...

Also, the best hope we have of getting a "true" value/unit for the singularity would be in terms of 10 X Stacy Abrams plus 10 x Moochell Obamy == One StacyMooch...

So, this latest discovery is about 30 StacyMooches...
And the only detectable Hawking radiation would be due to having to retch when observing the black hole in the data photograph...

[Hebrews 11:6]

So, a new metric for measuring black-hole appetites: # of earth-masses per second.

Imagine being on a planet and being told the sun and planets were on a collision course with a black hole.

I wonder what the effects would be as the planet was torn asunder?

[Hebrews 11:6]

All imagining aside: This earth actually is on an imminent collision course with the Great Tribulation, Jesus’ Second Coming and Millennial Reign, Armageddon, the New Heaven and Earth, and the Great White-Throned Judgment.

Thank you both for the explanations.
It is all perfectly clear to me now.
Yup.
