Phoenix A* vs. TON 618: Which One is Really The Biggest? | Black Hole Masses Phenomenon

🌟 Explaining the Black Hole Masses Phenomenon (or How to Determine the Real Mass of Black Hole?) + Solar System vs. Phoenix A* vs. TON 618 Size Comparison

📖 A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.

❓ So, how did I calculate, even if very approximately, but seemingly impossible (the real mass of black holes), if humanity does not have such information... or does it have?

🌐 We know that Phoenix A* is 100B SolarMass (SM), and TON 618 is 66B SM. But both of these masses are not relevant today. Like, we see space objects like they were thousands or billions years ago (depending on how far away the observed object is). Physics cannot “live” separately from time. It means that the data that we now have on hand doesn't correspond to the characteristics at the current moment of existing the black hole (for itself, not for the observer from the Earth!)

_________________________________

1⃣ PHOENIX A*
▫️ Look, we have Phoenix A*, which is 100B SM. It took 5.86 billion years (source: Wiki) for light to travel to reach the Earth, so we see it as it was 5.86 billion years ago
▫️ We also know that Phoenix A* grows by 60 SM per year (source: Wiki). Anyways, that's 5.86 billion years ago information, today's one may be way different, depending on how dense the cosmic environment the black hole has been in over the past 5.86 billion years.
▫️ We're doing some calculations...
🔹 5.86B years × 60 SM = 351.6B SM
🔹 100B SM + 351.6B SM = 451.6B SM
▶ *Phoenix A*: 451.6B SM*

2⃣ TON 618
▫️ TON 618 is 66B SM. It took 10.8 billion years (source: Wiki) for light to travel from TON 618 to Earth, so we see it as it was 10.8B years ago
▫️ Unfortunately, I didn't find any information about black hole's growing rate (or there's still no information about it..? If you find something, say to me!), so let's estimate: 50 SM per year (It’s OK to estimate and guess, based on the information that we have now (Phoenix A*: 60 SM per year), as long as it doesn’t violate the laws of physics and existence).
▫️ Some calculations...
🔹 10.8B years × 50 SM = 540B SM
🔹 540B SM + 66B SM = 606B SM
▶ *TON 618: 606 billion SM*

_________________________________

⚠ Naturally, all calculations are *VERY approximate.* It's based on the data that humanity has now, it's nearly impossible to accurately determine the current physical characteristics of the black holes, since this is influenced by a huge number of factors: changes in the density of the space environment, matter around, which need to be constantly monitored, changes recorded, etc., and maybe something else... But I think I got the point across..?

Bro explained better then all the other teachers in my school

For those saying Phoenix a is the “biggest” black hole the mass of Phoenix A was calculated using a model which links the star density profile of the galaxy to the adiabatic (without the transfer of heat) growth of the supermassive black hole at the core. This model is very new and doesn’t have a lot of strong backing in the scientific community yet, and this application of adiabatic growth has a limit which Phoenix A may approach. The reason the mass can’t be conventionally measured is because it is to far away for us to have good measurements of the dynamics of nearby star’s (phoenix a is~8 gigalightyears away), and doesn’t appear the way other quasar’s do. Ton 618 has a characteristic brightness which we can use to approximately determine it’s mass, despite it being much further away. so it might not actually not be the biggest. Be grateful that I wrote this,
So there is a chance that ton 618 or Phoenix a eats a galaxy, because ton 618 is larger now, and Phoenix a is too, ask questions in the reply’s anyways, if we were to look at Phoenix a with a telescope, we would look back in time and how many light years away it is, then that’s how much we look back in time (we won’t see things in space how they are now) and it would take that long to get the light to reach us, so the universe is growing too so there may be bigger black holes out here that we never discovered yet.

Phoenix A before: I am the biggest black hole
Ton 618 in 2023:Are you sure?

[akshajkatiyar]

Ton 618 grabbing the crown again for the largest black hole.

[mexicann]

Now let’s just pray and hope that Ton-618 makes a massive comeback 😂😂

[Egg]

Bro doing perfectly maths then i could💀💀

[glitch]

Sigma edit now: 🤡
Space edit forever: 🍹🗿💡📚

[cwareal]

welp thanks for doing the size comparison

[bertoxonline]

respect this guy for the solution that he maked🫡

[randompeople]

man i really love your content, keep it up.

You should make an short about J1144 size in 2023. It’s bigger than both of those.




So basically, this black hole (actually it’s a quasar) is known as J1144. It has the mass about 2.4 Billion solar masses
But since it’s 9.6 billion light years away from earth
That’s not it’s true mass

It’s growing at about one earth mass per second

Now let’s divide one solar mass by one earth mass that is 333, 000

Now let’s divide the amount of seconds in a year, which is 31, 556, 952 (on average)

So now let’s divide this number by 333, 000


That comes out to about 94.7


So this black hole is growing at 94.7 solar masses per year


Let’s times that by 9.6 billion

That comes out to about 909, 120, 000, 000 SM in 2023


I almost forgot to add the extra 2.4 billion solar masses




So, in total that is about 912, 520, 000, 000 SM in 2023 most likely





And also again, I almost forgot to say this thing is also a quasar which technically still a black hole, but it’s still growing

[Duran]

Your explaining the solar systems and universe and black holes and others better than my scientist teacher i already give you some likes and some subscribe

[kaosijdsowowd]

I LOVED THIS! Ma boy is still top 1! I always new TON618 is technically correctly bigger than Phoenix A*

[greens]

I’m subscribing just for how weel you explained this 👏👏👏👏👏

[BlenderKnowledge]

What name do you guys think sounds better of those 2 black holes?.

I personally think Ton 618 sounds really good. It sounds really heavy.

[klatikw]

So theoretically, TON 618 is still the biggest black hole ever, now. *What if they merged?*

[TidalVC]

So thats why TON 618 is the hardest impossible level in Geometry Dash

[БЗДУНЯРА]

WE STRAIGHT FLYING WITH THIS 🗣🗣🗣🗣🗣🗣🗣🗣🔥🔥🔥🔥🔥

[WaltuhPinkman]

Finally someone who will actually explain how big they are. And not someone who makes video and just writes what the biggest is, and then puts some cringe music in.
