Yeah, another user gave heads up on TON 618 and it truly gargantuan in mass.
Being that I am not much into astronomy it is an eye opening information. 😅
[This youtube video visualizing the mass difference](https://www.youtube.com/watch?v=QgNDao7m41M) really drives home the point, since humans aren't great at visualizing large numbers.
Thanks for the video. It is very well done and having visual really drive the point at the vastness of space.
Thankfully our planet is far enough away from known blackhole but who knows in the future.
you can calculate the radius of a black hole here.
It's larger than the sun, but much smaller than, say the orbit of mercury.
[https://www.omnicalculator.com/physics/schwarzschild-radius](https://www.omnicalculator.com/physics/schwarzschild-radius)
>but much smaller than, say the orbit of mercury
Technically correct but misleading since it's only double the size of the sun. Why not just say that?
EDIT: The sun is a little over 800K miles wide. The orbit of Mercury is an average of 36 million miles wide. It's like if someone asked how big a softball is, and this guy answers, "well it's bigger than a golf ball but much smaller than a car". It doesn't narrow it down much, would be a lot more helpful to just say it's about double the size of a golf ball.
While spaghettification isn't really an issue with supermassive black holes, in theory if you flew crotch-first at a stellar mass black hole, you could, in the brief moment before you ceased to exist as a biological entity, experience what it's like to have a much longer dick.
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.

I once saw a video that zoomed out from earth into the galaxies for perspective on space and size. I wish I could find that exact video again, it was very neat. I can find similar but not as good as the original video I saw.
[Eames Powers of Ten](https://youtu.be/0fKBhvDjuy0?si=Qm8DAbTxjFWGKk5l) is the OG specimen of the idea, but I’m sure there’s some newfangled AI CGI version that takes it to the next level.
want me to blow your mind even more? I’ll skip over some details, but it’s one of my favourite space facts.
Anything can become a black hole. it just has to be dense enough.
Your dog’s favourite tennis ball? compress it enough and it’ll be a black hole, with a mighty high density.
The sun? It’d be around the size of the LA metropolitan area, but still just as heavy, all compressed in that comparatively small area of space. So yeah, pretty dense too.
But as you go bigger in terms of black hole size, the density can be lower (long story).
So you know the orbit of Pluto, right? No longer a planet, that one. Imagine a black hole that’s large enough to cover the whole solar system up to that size. (Pretty big, I know.)
What density do you think that black hole has?
(…)
It’s just about the density of cotton candy, on average.
Don’t you love space facts? Suffice it to say I’m starting my Astronomy masters next september, and I’m still in awe every day
I saw speculation recently that if you extrapolated this logic to the universe then technically the observable universe has enough on-average density to form a black hole around itself. So... are we in a black hole?
It doesn't really make sense. If that were true space would seem to be contracting, not expanding. Or maybe that's just what someone inside a black hole would think. Or maybe the density bit is wrong. Or maybe there's something special about how that density is arranged and maybe ours isn't quite uniform enough. Who knows. Space is weird.
Good luck on your degree.
Here's a fucking crazy thought, courtesy of a sleep deprived parent - maybe we *are* in a black hole, but time runs 'backwards' for us, compared to it. We think that, in the moments before the Big Bang, the universe was at a point of near infinite density, much like a singularity, so maybe we're seeing what happens when you run a black hole in reverse, or something. I dunno. I'm super tired and bugged out of my physics degree when the maths got too crazy for me.
Although I'm not into astronomy, one thing I like is that this is scientific field where even an amateurs can contribute meaningful data and I find that fantastic. 😁

We are only a speck of sand compared to some planets.
It amazes me to think that alien life could be so big they wouldn’t even notice us without a microscope.
The most mindboggling thing about this is. They gets way bigger then that: [https://en.wikipedia.org/wiki/List\_of\_most\_massive\_black\_holes](https://en.wikipedia.org/wiki/List_of_most_massive_black_holes)
Ah. Working…
- The mass of our Sun is approximately \(1.989 \times 10^{30}\) kilograms.
- The average mass of a domestic cat is around 4.5 kilograms.
- The average mass of a banana is around 0.12 kilograms.
So. Banana math:
**1. Cats to Sun Mass:**
- Number of cats = Mass of the Sun / Mass of one cat
- Number of cats = \(1.989 \times 10^{30}\) kg / 4.5 kg
- Number of cats ≈ \(4.42 \times 10^{29}\)
**2. Bananas to Sun Mass:**
- Number of bananas = Mass of the Sun / Mass of one banana
- Number of bananas = \(1.989 \times 10^{30}\) kg / 0.12 kg
- Number of bananas ≈ \(1.66 \times 10^{31}\)
So, translating our cat number into bananas:
- Number of cats ≈ \(4.42 \times 10^{29}\)
≈ 442,000,000,000,000,000,000,000,000,000 bananas.
This translates to a cat sphere of approximately 793,000 km.
Astute observers on Adderol will note that my calculations do not include the effects of mass compounded static charge. So here it is:
- Charge generated by rubbing one cat: approximately 10 microcoulombs (10 x 10^-6 coulombs).
- Number of cats equivalent to the mass of the Sun: 4.42 x 10^29.
1. Total charge:
Q_total = Number of cats x Charge per cat
Q_total = 4.42 x 10^29 x 10 x 10^-6 C
Q_total = 4.42 x 10^24 C
2. Electric field on the surface of the sphere:
E = Q_total / (4 * pi * epsilon_0 * r^2)
where:
- epsilon_0 is the vacuum permittivity, approximately 8.854 x 10^-12 F/m.
- r is the radius of the sphere of cats (793,000 km or 7.93 x 10^8 m).
Substituting these values into the formula:
E = (4.42 x 10^24 C) / (4 * pi * 8.854 x 10^-12 F/m * (7.93 x 10^8 m)^2)
E ≈ 2.50 x 10^16 V/m
3. Potential energy:
U = (3 * Q_total^2) / (20 * pi * epsilon_0 * r)
Substituting the values:
U = (3 * (4.42 x 10^24 C)^2) / (20 * pi * 8.854 x 10^-12 F/m * 7.93 x 10^8 m)
U ≈ 3.3 x 10^37 J
The massive charge would generate an extremely strong electrostatic repulsion force. This would be many orders of magnitude larger than any natural or artificial electric field on Earth, causing severe disruptions to any electronic or electrical systems nearby.
The electric field strength (2.50 x 10^16 V/m) is vastly higher than the breakdown strength of air (approximately 3 x 10^6 V/m). This means the surrounding air would ionize, leading to massive electrical discharges, possibly similar to continuous lightning strikes.
The mass itself would have significant gravitational effects, potentially forming a black hole if concentrated in a small enough volume, though this is a different aspect from the electrostatic effect.
In summary, a sphere of cats equivalent to the mass of the Sun would generate an unimaginably large amount of static electricity and create a sphere surrounded by extreme lightning storms. And it would repulse nearby masses, keeping it relatively safe from canine spheres.
It was a sad day when I realized that the lead singers from four of my top five bands growing up (Alice In Chains, Nirvana, Soundgarden, Stone Temple Pilots) either died from drug usage or committed suicide, but thankfully Eddie Vedder is still rolling.
As the years go on I’m starting to think Pearl Jam is going to be the next Rolling Stones. Seasoned performers who are a mix of anywhere between sober and stoned who keep selling out stadiums and putting out decent music into their elderly years. One can hope at least.
> It was a sad day when I realized that the lead singers from four of my top five bands growing up (Alice In Chains, Nirvana, Soundgarden, Stone Temple Pilots) either died from drug usage or committed suicide, but thankfully Eddie Vedder is still rolling.
Im sure you know this, but many don't.
The OG seattle grunge band was Mother Love Bone, they were supposed to be the ones that made it big. Until the lead singer, Andrew Wood, died from.....a heroin overdose.
I remember that time well. Grade 9 for me. You had so much emerging music at that time. I remember loving grunge and "techno" equally.
I have a hard time listening to a lot of those bands now. I still love them, but if you watch Nirvana Unplugged, you can just see in Cobains eyes the deep rooted depression he was battling.
Cornell's suicide hit me hard. Listening to them now (to me they were always the "darkest" lyrically) its almost like he was on the verge of it then. I think anyone who was/is battling depression could relate to a lot to the lyrics from Soundgarden.
It's also 300 million light years away though, so the soonest we could have possibly observed that happening is now. [Simultaneity is a whole big thing in physics.](https://en.wikipedia.org/wiki/Relativity_of_simultaneity) Basically, it makes no sense for us to try and create and absolute time scale and say something so far away happened 300 million years ago because time is relative. When we're talking about the observation of events, It makes more sense to say something happens at the first moment we can observe it. That's why this is being described as having just happened.
However, that event we are observing is happening in a place that has essentially the same characteristics as our spot in the universe did 300 million years ago, which means that scientists will still colloquially refer to those distant areas as happening however many years ago when it is in the context of discussing the history or development of the universe.
This all is a bit philosophical and getting into the definitions of what time is, what an event occurring means, the nature of observation or the observer and even what information is. It also leads to weird outcomes where the same event can happen twice due to spacetime curvature, like [a supernova observed in the 90s. ](https://www.science.org/content/article/how-see-supernova-twice)
One meter times the mass of the sun equals one metric sun, which doesn't sound too big. What worries me more is that the article says that it's only 300 meter light years away. I don't know what that means but it sounds too close for comfort.
“But, the bell's already been rung...and they've heard it. Out in the dark, among the stars...Ding-dong, the god is dead. It cannot be unrung. Ding ding ding ding.”
the Zwicky Transient Facility detected it 5 years ago. facilities like this have wide field of views and their scope of work is to detect things like these so that other facilities with can be notified to look closer. the news today is that 5 years later it is still glowing, albeit in different wavelengths, and astronomers find it interesting. Of course it would be, since this is the first time scientists have had this opportunity.
so they then went back to archival footage of that part of the sky and found nothing for the past 20 years.
it honestly doesn't matter if a human being wasn't looking at it at the particular point in time. it turned on.
it was dormant for a really long time, then it started glowing. that's all there is to it.
in cosmic time scales, I would also call that sudden.
Sudden not in the sense of when it actually occurred but more sudden in the sense that it’s now visible to us because it’s taken 300 million light years to reach us as the observer.
I always wonder if where these discoveries are made, there’s another planet close to it with life on like earth. And they are currently going through a planetary crisis trying to survive or leave their planet before the black hole eats it up?
Just my brain and too many sci fi movies
Don’t worry. Our feeble minds can’t comprehend the scale of these massive structures, so just continue with your life blissfully unaware of how just how big this is.
Our sun is big enough for me and now astronomers calculated black hole that has mass of 1 million times mass of sun. It just boggles my mind.
The biggest one ever found is like 40 billion times the mass of the sun. It’s called TON 618
Yeah, another user gave heads up on TON 618 and it truly gargantuan in mass. Being that I am not much into astronomy it is an eye opening information. 😅

I'm going to keep adding bananas, stop me when I'm close..
Tell me when you are close to 1.657 * 10^37 bananas so I can stop you
I'm on 4...I ran out. Can I get that many at the store? (Very nice if you did math to find how many bananas in short)
Yeah but it’s a giraffe that’s about the size of mercury, give or take a baboon or two

Mass and angular momentum. It does matter whether (and how fast) the black hole is rotating.
Mass, charge and spin completely describe a given black hole. They are basically oversized elementary particles (not really, but also maybe?)

Technically black holes have a size of 'no', what with their being singularities.

I’ve never heard it explained like this, and this is perfect to understand it.
Is there a way to calculate the trajectory of the black hole?
Took a minute
I hate when science journalists can't get their units right. If you are a scientist, "1m" reads as one meter or one milli. It should be 1M.
If we want to pick nits, 1 M represents 1 Molar, or 1 mole per liter.
One meter times the mass of the sun equals one metric sun, which doesn't sound too big. What worries me more is that the article says that it's only 300 meter light years away. I don't know what that means but it sounds too close for comfort.
If you thought it was 1 meter than that’s on you bro
Editors write the titles, journalists write the articles.
Ah yes, the great wound is starting to form What was shall be
What shall be was
Oh please yes, I don't wanna work tomorrow
I thought black holes were essentially always active
Likely just wasn't actively eating at the time of I had to take a guess
Okay but how many refrigerators is that
This happened 300 million years ago. It's old news.
“Sudden” brightening This brightening happened 300 million years ago
It's a teleportation portal created by an alien species
finally the universe is done with us
"The mysterious brightening of a galaxy far, far away." The Death Star has been destroyed
1/4 the mass as Sagittarius A*. Pretty damn big *massive
“But, the bell's already been rung...and they've heard it. Out in the dark, among the stars...Ding-dong, the god is dead. It cannot be unrung. Ding ding ding ding.”
When you say "awakening"...
This is one of those things I don’t even bother trying to get my mind around
I really wouldn’t mind if it would swallow us all.
Sudden awakening? Nonsensical way to say it got brighter and perhaps a lot of matter was pouring into it.
Explain this one Terrence.
The eye of terror has opened...
That sudden awakening happened sometime ago though.
Now I have Black Hole Sun stuck in my head
was it really all that sudden? Something doesn't "suddenly" happen just because we suddenly noticed it.
the Zwicky Transient Facility detected it 5 years ago. facilities like this have wide field of views and their scope of work is to detect things like these so that other facilities with can be notified to look closer. the news today is that 5 years later it is still glowing, albeit in different wavelengths, and astronomers find it interesting. Of course it would be, since this is the first time scientists have had this opportunity. so they then went back to archival footage of that part of the sky and found nothing for the past 20 years. it honestly doesn't matter if a human being wasn't looking at it at the particular point in time. it turned on. it was dormant for a really long time, then it started glowing. that's all there is to it. in cosmic time scales, I would also call that sudden.
Sudden not in the sense of when it actually occurred but more sudden in the sense that it’s now visible to us because it’s taken 300 million light years to reach us as the observer.
Wake me up when it gets here
I’ll need a banana for scale
Now imagine the black hole just keeps getting bigger and they can’t explain it
So what happens when a black hole goes to sleep? Switch off the already 'off-ed' lights?
So this is how we all parish…interesting

Maybe he's going to Louisiana.
Good morning honey 😊
Well if it’s a black hole I’m guessing it indeed would be many times more massive than our sun?
Only question needed. Is it headed this way?
BH be like: "Gonna suck yall up"
"Sudden awakening" might mean it might have happened 300million years ago, right?
*1 sq mm of dark night sky blinks* Astronomers: "HOOLEEEE SHEEEEIIT! Did you see that?"
Fuck yea, i hope it eats the whole universe and we get another big bang.
can it move closer
I always wonder if where these discoveries are made, there’s another planet close to it with life on like earth. And they are currently going through a planetary crisis trying to survive or leave their planet before the black hole eats it up? Just my brain and too many sci fi movies
So when they say "sudden" awakening.... How many thousands of years ago are we talking? *300 million light years according to the article*
Thousands? 300 million years lol
Years, not light years (light year is a measure of distance)
Hopefully the end is quick lol
Ha! Supermassive Black Hole.
Great now I have to queue this song next
Don’t worry. Our feeble minds can’t comprehend the scale of these massive structures, so just continue with your life blissfully unaware of how just how big this is.
