Can Black Holes Grow In Size? (Yes, But There Is…)

Black holes are one of the scariest and most beautiful things in the universe. Even light can’t escape them and because of that scientists don’t exactly know what would happen if you fall into them.

Some suggest that you’ll come out of a totally different place in the universe, some say that you will be transferred to another galaxy, and others believe that you will die instantly due to extreme pressure and force.

Now, black holes are filled in the universe, in fact, in our own milky way galaxy, it is estimated that more than 100 million black holes are present.

Can Black Holes Grow In Size?

Yes, but it depends. If a black is consuming a lot of material, like stars, planets, and gases, it will grow in size, but if it isn’t eating something, then it will shrink.

Black holes shrink as well, due to Hawking Radiation. According to the late physicist Stephen Hawking, black holes release tiny amounts of energy every second and because of that, they will one day simply vanish.

However, even a black hole with one solar mass would take around 1067 years to evaporate. You can’t even imagine how insane this number is.

Our universe is just 1.4×1010 years old, it is still very very very less than 1067 years. Hawking Radiation is painfully slow!

Biggest Black Holes In The Universe

Let’s look at some of the largest black holes ever discovered. You would be amazed!

1: Phoenix A* Black Hole (Mass: 100 Billion Suns)

This phenom is 100 billion times heavier than the sun. And, its even horizon is crazy big, it is around 3,900 Au. One Au is equal to 147 Million KM or 93 Million Miles.

2: TON 618 (Mass: 66 Billion Suns)

The blue dot above is not just a normal star, it is TON 618. Its galaxy is not visible, it has outshined its entire galaxy.

It used to be the largest, and I’m sure you may have heard about it before because many people have talked about this giant black hole.

This black is insanely luminous, it is 140 trillion times more luminous than our sun. Even though it is 10 billion light years away from us, but it shines like a star in our galaxy.

When it was discovered, scientists thought that is in fact a star of our galaxy, but little do they know, it is a monster!

3: 4C +74.13 (Mass: 51 Billion Suns)

4C +74.13 is a galaxy cluster present 2.6 billion light-years away, at the center of this cluster a massive monster can be located. This monstrous black hole is around 51 billion times heavier than the sun.

4: Holmberg 15A (Mass: 40 Billion Suns)

Holmberg 15A is another ultra-massive galaxy, it is around 700 million light-years from Earth, and it was discovered way back in 1937 by Erik Holmberg.

The beast gained popularity as it was reported to have the largest core ever observed in a galaxy, spanning some 15,000 light-years.
