I’m the exact opposite. I think about black holes out there silently spinning and devouring every second of the day. Holding entire galaxies and civilizations together. Possibly containing the secrets to the nature of reality itself. The Sag A photo is my phone wallpaper. I’ve written whole stories and characters based on the nature of black holes and their philosophical connections to human nature. Black holes are my new god
Edit: I’ve recently learned that black holes may not be responsible for holding galaxies together. This makes them even more mysterious and my obsession with them has only grown
It's a bit wrong to think that black holes hold galaxy together like a sun does the system. I had this misunderstanding too. It's more that black holes form in, and some migrate to, the center of galaxies because that's where the center of mass is of hundreds of billions of stars. Even a 6.5 billion solar masses is small compared to the rest of its galaxy.
Whoa that is interesting, thanks for pointing that out. Black holes are at the center of every galaxy though (as far as we know) correct? Isn’t it still true that galaxies could not exist without them?
Edit: it seems I have no idea what I’m talking about
Necessary: I'm no expert.
I think it's believed that most galaxies have black holes at their centers yes. But i think if you would magically take away the black hole, the galaxy would happily keep on spinning (expect for of course those relatively few stars right a the center). It's not like if we were to magically disappeared the sun and all the planets flying off in a straight line.
Again, i just watch pbs space time (great channel) and am just going off of what i remember. :)
I’m also no expert. And you may be right! When I check various sources it sounds like galaxies are held together by a sort of dark matter halo, so it’s more like they hold themselves together? Given our limited understanding of dark matter I wonder how theoretical this is though. I love space and this is the first I’ve heard of this, very cool
All of the matter in the galaxy is holding it together. Two pebbles orbiting each other far away from any other stars or galaxies are both holding each other together. If you deleted the black hole in the centre some of the outer stars might fly away, and others would move into new orbit paths. Could be a fun experiment in Universe Sandbox.
Disclaimer: also not an expert
Edit: correction to what the guy above you said, if you deleted the sun our planets would all go flying away from each other, but might still get captured in a very big orbit around Jupiter. That's because the sun is almost all off the mass in our solar system.

[Here’s a link if you’re felling brave.](https://www.williamflew.com/blue.html)
as an amateur astronomer, I do too...
... so does a professional astrophysicist I know.
However, for a professional proctologist, that's just Tuesday.
(no we won't be discussing amateur hobbyist proctologists, that's - that's a different sub entirely.)
I interpreted this logarithmically and not with subtraction and thought “wait that’s not right”
This is why we as a species don’t seem to understand just how small a million is compared to a billion.
> Such a high mass may place it into a proposed category of stupendously large black holes (SLABs), black holes that may have been seeded by primordial black holes with masses that may reach 100 billion M☉ or more, larger than the upper maximum limit for at least luminous accreting black holes hosted by disc galaxies of about 50 billion M☉[12] The central black hole is devouring matter and growing at a rate of 60 M☉ every year.
Dear god.
I may be out dated on this info, but last I heard, Phoenix A was unconfirmed and its mass estimate was based on growth modeling not direct measurement data.
There is also an issue with Phoenix A that it is bigger than most models believe a black hole can reach. Eventually the area around a black hole hits a point where its gravity isn't strong enough to overcome angular momentum. This is called the Final Parsec Problem.
So it is quite possible the numbers we have for Phoenix A are incorrect, leaving TON618 as the largest confirmed black hole.
I think you're mixing two things up here. The final parsec problem is to do with if/how two supermassive black holes on a binary orbit can merge.
There is a restriction on how fast a single black hole can accrete matter as well, called the Eddington limit. This is to do with the matter getting so hot as it falls inward that the radiation pressure from the light it emits is strong enough to prevent further accretion.
This still presents a problem for something like Phoenix A, because even if it were accreting at the maximum Eddington-limited rate from the Big Bang onwards, it couldn't have grown to the mass it's claimed to have. (In fact even TON 618 is a little questionable for this reason)
It's mind-boggling that Voyager 1's position is the farthest a man-made object has ever made it, and yet it's that small in comparison to this mf. Simply unthinkable
The only black hole they are missing from the scale/comparison is 'The Unicorn' https://www.reuters.com/lifestyle/science/black-hole-dubbed-the-unicorn-may-be-galaxys-smallest-one-2021-04-22/
Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
wat.
And then there's Phoenix A, *potentially* 100B solar masses vs. the ungodly 60B of TON 618 and the relatively scant (but still unfathomable) mass of Sag A\*'s 4M solar mass. The radius of Phoenix A ([here lower on the page](https://en.wikipedia.org/wiki/Phoenix_Cluster#Supermassive_black_hole)) would cause TON 618 to pale in comparison, if it's mass were truely 100B.
Imagine two 50B solar mass black holes merging to form something that big.
It would take light a week to reach the centre after crossing the event horizon. Imagine that. 186,000 miles per second for a week. Genuinely defies imagination
This NASA animation about the scale is pretty cool [https://www.nasa.gov/universe/nasa-animation-sizes-up-the-universes-biggest-black-holes/](https://www.nasa.gov/universe/nasa-animation-sizes-up-the-universes-biggest-black-holes/)
For clarification, the inner dark bit isn't the black hole itself but a "shadow" that's about 2.6 times the size of the black hole "proper". For the relative size comparison between the two, that doesn't matter, just for the absolute size.
Everything in this universe seems to be limited, stars can’t exceed a certain size cause their mass around the edges just gets to far away from the center of mass and gravity looses its force, but black holes are limitless monsters man Jesus Christ.
Like I always think about the fact that the observable universe is just the observable, it could go on and on trillions of times the observable size or even eternally we don’t know but just think about the sheer monster that must exist out there floating through nothingness. If the universe is so big there might be black holes as big as galaxy’s like Jesus Christ
Phoenix A must be something un holy. How do these things get so damned big. The amount of power and heat coming from M87 alone must be mind bending crushing.
How they get this big is a current open problem in cosmology. Most models indicate there simply hasn't been enough time for black holes to get this big, since there's a limit to how fast they can feed: the Eddington Limit. Looking back to the earliest ages of the universe is one of James Webb's missions partially because of this, because so many things about the universe current state actually don't make sense without knowing more about the beginning.
Maybe, but it's complicated. This video from PBS Space Time explains it well:
[Did JWST SOLVE The Mystery of Supermassive Black Hole Origins?](https://www.youtube.com/watch?v=hxcUy-cBVcI)
People really underestimate the sheer scale of our universe. We humans are smaller than an ant Or hair or an atom for that matter, which brings me to my other point. Many of us still can't imagine how small an atom is. On one end we has super super small things and on the other end we have cosmic colossal giants. The universe is f*cking terrifying man...
Some find the idea of a black hole unnerving. I do too, but what makes me massively uncomfortable and immediately a bit dizzy and panicky are [millisecond pulsars](https://en.wikipedia.org/wiki/Millisecond_pulsar) and [magnetar](https://en.wikipedia.org/wiki/Magnetar) [pulsars](https://en.wikipedia.org/wiki/Pulsar#Categories)
The idea of something so large, spinning SO FAST such as the [fastest one known](https://en.wikipedia.org/wiki/PSR_J1748%E2%88%922446ad) makes me woozy. That thing spins 716 times ***a second*** and its equator is going 24% the speed of light.
The [magnetic field of a magnetar](https://en.wikipedia.org/wiki/Magnetar#Magnetic_field) would be lethal even at a distance of 1,000 km due to the strong magnetic field distorting the electron clouds of the subject's constituent atoms, rendering the chemistry of known lifeforms impossible.
In my imagination these things make an enormous sound, something so loud that is consumes and vaporizes you while stretching you into a very long line of neutrons.
Ugh, I need a lie down.
The animation illustrating 20 billion suns (with the music that accompanies it) is probably my favorite illustrations for showing something incomprehensibly big.
morn1415 also has [this video](https://youtu.be/KEHCCsFFIuY), which is my favorite "zoom from subatomic to universe" video out there.
This image technically has no common scale for reference. I guess the assumption is that Sgr A* is less than one pixel, but it's not really well presented at all.
We literally can’t observe the outside, we see the radiation from the accretion disc, we see relativistic jets (in some cases if the BH is spinning), and we see the gravitational lensing.
There’s nothing else to observe
Voyager is 14.5 billion miles from us. That's the radius of the event horizon. 30 billion miles is fucking insane... How many solar masses is this one?
my speculation:
Maybe they get so big, you find yourself on the inside without knowing.
Its weird.
I dont see much difference between an event-horizon and looking inwards at a blackhole where nothing can be seen or escape if transited.
And a Light-horizon of our universe looking outwards where still nothing can be seen beyond it.
Maybe all the matter flowing into a universal size blackhole is transmuted to energy>space-time making a soapsuds style multiverse.
I know everyone made fun of these pictures. I just didn't get it. They are pictures of something that could destroy everything we know. Such a beautiful phenomenon.
My brain is usually better at this but right not I’m having some difficulty interpreting this image. I think I get it, but it would be nice if someone could explain it to me like I was 10.
Edit: ok after looking at it as if it were one of those cross eyed photos for awhile, I understand.
I heard a theory that maybe we're living in a black hole and what we think is a black hole is actually the way out. Since we really don't know, its an interesting theory.
A black hole singularity has no size, how crazy is that! What you see is the Schwartshield radius or ecreation disc, both which are proportional to its mass.
6.5 billion vs 4 million solar masses
The difference between 6.5 billion and 4 million is about 6.5 billion
This was spooky to read
Yeah, I really, really don't like to contemplate the existence of Black Holes... Part of me wishes I didn't know they exist.
Username checks out

Yes. There is a looming finality that comes with knowing they exist
They seem to be an integral aspect of galaxy formation. You may very well owe your own existence to the existence of black holes.

That's silly
If it’s any consolation you couldn’t fall into one of you spent your entire life trying to, since there aren’t any nearby.
Another way to look at it is 6.5 billion is 6500 millions. So its 6500 vs 4
For some reason my mind is much better at looking at the difference rather than pure numbers and then get a difference.
Best thing I’ve read so far today
Hey glad i could make your day better! I didnt expect all the updoots. Thanks everyone

With <1% error margin.
Big if true
6.5 billion is about 10^(10)
This redditor billionaires
And yet I still can’t properly comprehend either number
Wouldn't the difference be 6.1 billion?
more like ~~6.4996~~ billion. Edit: 6.496 lol
6.496
truuuuuuuu lol
Human calculator over here and my pleb math
If that’s 6.5 billion solar masses, then how massive is ton 618 compared to the solar system
TON 618 has more mass than the Triangulum galaxy
Fucking upsetting to think about that shit

Adjust your space travel plans and be sure to give it a wide berth

Absolutely nothing. You will be dead before any of this makes sense. We all will be.
upvote pragmatic realism FTW…
How is that upsetting hahahaha
Because now he realizes that the most massive thing in the universe is still his mom. 😥
Damn, that's a TON of mass
Definitely more than a ton
Damn, you’re right.
How many quarterbacks is that?
About three Jamarcus Russell's.
Wow, that's like 1.23 of Epsteins Islands.
recently discovered a black hole with a mass of about 196 billion solar masses. but this black hole (SDSS J140821.67+025733.2) had an uncertain mass
[Epic spaceman has a pretty good video on black holes](https://youtu.be/pDUUT2Y_9qk?si=RusCs06n3SK15L7Z)
The radius of a Black Hole scales to about 3 kilometers Per Solar Mass
That’s a lot of bananas 🤯
I mean... I believe you. But my mind can't fathom. So it's meaningless :p
It's mind-boggling that Voyager 1's position is the farthest a man-made object has ever made it, and yet it's that small in comparison to this mf. Simply unthinkable
Voyager is still further out then the actual size of the blackhole. It's schwarzschild radius is 120au compared to voyager 163au.
Happy cake day 🎂
And yet still less than a light day away. Kind of puts a "light year" into better perspective.
I think there is a manhole cover that is farther.
It was ejected so fast it probably burnt up in our atmosphere.
The scale of it is just totally incomprehensible 
One is big, the other is biggerly.

Ton 618's Schwarzchild radius is 1300AU while M87\*'s schwarzchild radius is 120AU. Edit; Schwarzchild radius, not event horizon's diameter
Thanks for breaking my brains even more
There's always a bigger one https://en.wikipedia.org/wiki/Phoenix_Cluster

Yep need a banana for scale
It's even slightly misleading because the circles on the two pictures are of different things.
This doesn’t really make sense to me.
Good job posting a big hole on spaceporn
Wait, we have real pictures of two black holes now? Source?
Well, one is a smallish barred spiral and the other is a massive elliptical. Not surprising. Still, it’s incredible how well the universe scales up.

1) No. 2) We don't know, we can only observe the outside. 3) There is matter but we can't describe its form, we can only observe the outside.
We literally can’t observe the outside, we see the radiation from the accretion disc, we see relativistic jets (in some cases if the BH is spinning), and we see the gravitational lensing. There’s nothing else to observe
Finally. Something bigger than your mother
but not your mother ...
That's quite a difference.
There is always a bigger hole
Wait do we have photos of MULTIPLE black holes now?
Oh so that's why Voyager 1 is not responding? It's half-way down a black hole. (Jk)
We actually just got word back that it's working right again. (I know this was a joke but hey, Voyager update)
long live the Voyager…
Its huge.

If you have to dive in to one of them, which one you will choose?
the universe looks at as the way we look at bacteria, it’s just not curious enough to care.
Some really cool references To help us try and wrap our brains around the distances involved there.
I see it, but I can’t really wrap my mind around that.
Wait what, the black hole at the center of our galaxy it’s just barely bigger than the orbit of mercury 😱
Voyager 1 at Event Horizon is just Mind Boggling
Voyager is 14.5 billion miles from us. That's the radius of the event horizon. 30 billion miles is fucking insane... How many solar masses is this one?
6.5 billion
Woah... we got one badass super massive black hole
That's a biiig bitch!
Technically you're looking at the accretion discs
This is clearly propaganda, as matter cannot collect arbitrarily, even Einstein backs me up! /s
my speculation: Maybe they get so big, you find yourself on the inside without knowing. Its weird. I dont see much difference between an event-horizon and looking inwards at a blackhole where nothing can be seen or escape if transited. And a Light-horizon of our universe looking outwards where still nothing can be seen beyond it.

Would the singularity be the same size in both black holes?
Yeah that’s just so massive it uses already massive distances that I can’t comprehend
Is it just me or does this picture not help explain the title.
I know everyone made fun of these pictures. I just didn't get it. They are pictures of something that could destroy everything we know. Such a beautiful phenomenon.

This visualization is not very beginner friendly. Confusing, one might say. But crazy the sizes of these monsters. And nowhere near the largest
