The discovery of an "impossibly" massive black hole in the Milky Way, only announced a couple of weeks ago, now looks to be debunked. Three separate papers available on the pre-print server arXiv have all called out the same problem.
The crux of the issue - it appears that the light interpreted as emanating from the accretion disc of the black hole might have another source entirely. This, in turn, means the mass measurement derived from that light is likely incorrect.
This may worth something:
'Monster Black Hole' Discovery Was Wrong — But That's How Science Progresses, Scientists
Apparently, that " monster black hole " that researchers found isn't so monstrous after all. But finding errors and working to correct them in how science pushes forward.
In a recent study (a peer-reviewed study published Nov. 27 ), a team of scientists reported the discovery of the binary system LB-1, which contains a star and, according to the findings, a black hole companion 70 times the mass of our sun . This was major news, a stellar-mass black holes (black holes formed by the gravitational collapse of a star) are typically less than half that massive.
Raiders ‘Black Hole’ Regulars Share Coliseum Memories as Clock Ticks Down to Oakland
OAKLAND (KPIX) — For Raiders fans, the Coliseum is a treasure chest of memories. From the tailgating parties to the daunting Black Hole, the curtain will most likely close on this chapter of Raiders history on Sunday.
Raider Nation has a special relationship with its team and the heart of that relationship sits at the end zone known as the Black Hole.
Rob Rivera, one of the co-founders of the Black Hole said, "It's heartache. Every fabric of what I do on a daily basis has something to do with the Black Hole."
"We Never Had an Ending:" Why Disney's 'Black Hole' Lost to 'Star
“ A journey that begins where everything ends…” That was the tagline on the poster for The Black Hole , Disney’s $20 million sci-fi gamble in the post- Star Wars game, essentially spelling out its reality in the marketplace in 1979.
With its starfield setting, stormtrooper-like sentries, swashbuckling laser battles and high-end special effects work — not to mention saturated merchandising by the Disney machine — The Black Hole was clearly a response to the 1977 George Lucas juggernaut and was destined for direct comparisons when it arrived in theaters two-and-a-half years later.
And here's another article:
Black hole theory WRONG: Scientists massively overestimated size of 'monster black hole' |
Professor Jifeng Liu said at the time: “Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution.
“Therefore, they should not leave behind such a massive remnant. LB-1 is twice as massive as what we thought possible.”
However, like most things which are too good to be true, the black hole might not actually be that big.

Three new studies now highlight the likely errors from the Chinese Academy of Sciences, with two of the papers stating that the scientists analysed the data incorrectly, and another which shows the more likely lower mass of LB-1.
Tour 10 of the Closest Black Holes to Earth | Discover Magazine
By nature, black holes are impossible to see directly. But astronomers can sense their presence by the way they interact with their environments, letting us glimpse these objects whose gravity is so strong that nothing can escape. In the past century, not only have astronomers shown that black holes do exist, but they've found dozens in our own galaxy.
However, based on the number of stars in our galaxy, there should actually be tens of millions out there. The trouble is that, unless they're near another star, they can be hard to detect. In these binary systems, a black hole can steal material from its companion star, generating distinct X-ray light in the process. A 2016 paper reported 77 nearby candidate black holes from such X-ray observations.
Discover's Science Images of the Year 2019 | Discover Magazine
The single most compelling science image of the year is indisputable. The first picture of a black hole, released by the Event Horizon Telescope, was a staggering feat requiring hundreds of scientists and multiple observatories spread across the face of the Earth. The resulting image, of the supermassive black hole at the heart of the M87 galaxy, is the first time humanity has gazed into the impenetrable darkness at the heart of one of the universe's most mysterious phenomenon.
'Impossible black hole' discovery in Milky Way may have been just that, as scientists spot major
The central thesis in all three papers, coincidentally published around the same time, is that the light interpreted as coming from this behemoth black hole may have come from an entirely different source.
In the original paper, astronomers led by Jifeng Liu of the National Astronomical Observatory of China, claimed the existence of LB-1, a black hole located 15,000 light-years away with a mass 70 times that of the Sun, something previously believed (and now most likely confirmed) to be impossible.
