The Monster Black Hole: TON 618

Introduction
Black Holes are one of the most mysterious objects in the Universe, or are they? Almost all galaxies have their black hole at the center, even our galaxy has. We all know our black hole at the center of our galaxy, it is called Sagittarius A*. But what if we replaced the black hole with the biggest known, TON 618?

What is TON 618?
TON 618, simply referred to TON is as well as the largest known black hole. You will take 2 weeks of crossing at the speed of light at this black hole. That is, if you didn't die. The 2nd largest black hole is as well as called J2157. It's also the fastest-growing black hole, and to stay in good shape, it gobbles up matter with a rate of about 1 mass of sun per a day. Lets explain about more things below.

What type of a black hole TON 618 is?
Because of some unusual radio emissions, it was categorized as a quasar, not inside the Milky Way but 10 billion light years away. It is incomprehensibly far away, but thanks for this safe distance. And you might ask, what is a Quasar? It's when a central galactic black hole is surrounded by a huge accretion disk. TON 618 is so bright, that it outshines the galaxy it lives in. That's 150 trillion times brighter than the Sun and as well 10,000 times brighter than all stars in the Milky Way galaxy combined, which contains 300 million stars.

How did this black hole got so big & how will it disappear?
For smaller black holes - it's simple. A star goes boom, while the core goes moob. But how about these incredible big black holes? No star can possibly result in a black hole this big. Scientists have estimated that ultramassive black holes have an upper limit to mass - 50 billion solar masses. When a black holes this big, it would consume the unstable part of the accretion disk around it, leaving only the stable part. Now here's the issue: TON 618 weights 66 billion Suns, which passes the limit of 50, and how? Our answer is the good old - we don't know. Maybe another monstrosity collided with TON 618. Everything don't last forever, not even black holes. They slowly lose mass by evaporating due to Hawking Radiation. But this is an incredibly slow process. It would take TON 618 $$10^{99}$$years to completely evaporate.

Conclusion
Will we find bigger ones? Maybe. Do they exist? Certainly yes. There is a very long way until everything in the universe decays.
