APOD: A Plurality of Singularities at the... (2018 May 12)

[neufer]

Based on the dynamics of a cluster of black holes, I'd go with murmuration.

But a starling would signify a young star whereas a black hole is an old dead star.

A bloat (hippopotamuses) of black holes.
..............................................
A horde (gnats & crows) of holes.
A host (sparrows) of holes.
A hover (trout) of holes.

[leelu]

It's obvious: a "collapse"!!

[Chris Peterson]

A minefield?

• A collupsus

or it mought have been due to a collupsus
of his back promises, as others looked at it.

[starrdust]

A cloud of black holes (referencing hatched clouds of black flies/midges)

[GoshOGeeOGolly]

A Hokey Pokey of Black Holes. They are, after all, mere theory. HAHAHAHAHAHAHAHA. Hokey Pokey. Anyone wanna dance? Neufer you have to remember that one!

[neufer]

Nothing fancy is needed, "black cluster" would suffice.

As Mr Tyson often likes to point out, astronomers call it as they see em, unlike other sciences. No new words, or foreign words, just comparing the discovery to known properties by making a comparison. E.g.: very big reddish star: red giant; very small galaxy: dwarf galaxy; compact star predominantly made of neutrons: neutron star; spots on the Sun: sunspots; a rapid expansion of everything at the beginning of time: big bang. It could extend to a “group of a black holes”: e.g. black cluster. Or maybe when we learn more about the behavior (movement) of the group, we can compare it to animal behavior, and adopt that animal’s collective noun in a slightly more poetic nomenclature.

• A bluster

bluster (n.), 1580s, "a storm of violent wind," from bluster (v.). Meaning "noisy, boisterous, inflated talk" is from 1704.
......................................
bluster (v.), late 14c., "stray blindly or blunderingly, wander aimlessly, go astray;" c. 1400, of persons, "shout loudly and angrily," from a Low German source, such as Middle Low German blüstren "to blow violently," East Frisian blüstern "to bluster," probably from the same source as blow (v.1), or perhaps imitative.

A collective noun for a group of black holes - Suckers

When the Swedish company Electrolux was going to launch its brand of vacuum cleaners in the U.S., the company decided on the following slogan:

Nothing Sucks Like Electrolux!

Who would have guessed that this humble sucker of a vacuum cleaner was the true black hole of house cleaning in the 1950s?

cauldron of black holes

[Boody]

A lot of black holes.

[heehaw]

I was sitting at the faculty lunch table (with others including one Dean) when a group of five Deans entered the dining hall, and someone said "Look, a gaggle of Deans!" The Dean sitting at our table said "no, no, surely its a pride of Deans!" I piped up "that's because they're always lion."

A minefield?

EXCELLENT!

[alcor]

With such a pack of black holes, there should exist hyper-velocity black holes thrown out of the center by the massive Sgr A*. With perhaps a lot of luck one should even find a hypervelocity binary including a black hole. Or have researchers already found one?

Just as research show it is possible for casual stars being thrown away from the Milky Way center by the massive black hole (https://en.wikipedia.org/wiki/Stellar_k ... city_stars), with velocities of around 1000 km/s.

I chose a pack of black holes, as in pack of wolves. I would prefer to stay away from both of them. And black holes rhymes somewhat with wolves.

[jimbo48]

Anyone notice that all the black holes are on the left side of Sgr A*?
Why is that? Is it related somehow to possible counterclockwise rotation with the left side coming at us?

[hoot]

A "disappearance of Black Holes".

[hoot]

Oops! I meant; A "disappearance" of Black Holes. Bad typing . . .

[Stardance Alpha]

Obviously .... A Singularity Cluster .... or perhaps a Singularity Cloud .... or a Festival of black holes, or a Convocation, ..... anything but Seminar, puhleez!

Why the left-handed polarity???? Anybody understand this?

• 1) A selection bias of the survey, itself.
  2) Sgr A* doesn't accurately represent the center of the Milky Way.

A SUCK of Black Holes. That was the first thing that came to my mind when I thought about many black holes in one place... it was just a giant suck of holes.

[Catalina]

A brood of black holes.
I have read so many times about the "super-massive black hole" at the centers of galaxies. I understand that Sig A holds that title for the Milky Way. Is it likely that these other galaxies have collections of lesser black holes at their centers, as well? What keeps them from swallowing each other up?

[Brit_in_Exile]

I thought Calcutta but some other folks beat me to it, so how about a Sucker of Black holes. For example "Wow, all those Black Holes, those suckers could rip the chrome off a Harley-Davidson"

They're just stellar mass objects orbiting a central mass. Unless they come close enough to collide with something (which is rare), they're no different from stars. Their gravitational attraction is the same as stars.

A maw of black holes.

As in The Maw; a cluster of black holes near the planet Kessel in the Star Wars universe.
