The Most Extreme Black Holes In The Universe

A black hole is a celestial object with a gravitational field so strong that nothing, not even light, can escape from it. They are formed from the collapse of massive stars, which occurs when the core of the star runs out of fuel and can no longer support the outer layers, causing the core to collapse under its own gravity.

Black holes are characterized by three main parameters: their mass, spin, and electric charge. The mass of a black hole is typically several times that of the Sun, but can range from a few times that to billions of times. The spin of a black hole is determined by the angular momentum of the matter that collapsed to form it. The electric charge of a black hole is usually zero or very close to it, as the charged matter tends to disperse before it collapses.

There are two types of black holes: stellar and supermassive. Stellar black holes are formed from the collapse of a single massive star and are typically a few times the mass of the Sun. Supermassive black holes, on the other hand, are found at the centers of galaxies and can have masses billions of times greater than that of the Sun.

Black holes are invisible, as nothing can escape their gravitational pull, but their presence can be detected by observing their effects on nearby matter. When matter falls into a black hole, it heats up and emits X-rays, which can be detected by telescopes. Black holes are important objects in astrophysics and are thought to play a crucial role in the evolution of galaxies.

Space can be a dangerous place.

Take black holes for example.

They are some of the most violent objects in our universe.

Powerful enough to tear entire stars apart.

Gravity is your secret weapon.

See, you can squeeze more mass into a smaller space.

the attraction becomes stronger. For example, to turn the Earth into a black hole,

I need to reduce the diameter to less than 1 inch.

But real black holes are much bigger

It packs a lot more mass than Earth.

Black holes can get really big.

There are three general types of black holes.

The smallest is a stellar black hole,

The shape of a giant star after it explodes

and it crashes like this

about 40 miles in diameter,

About three times the length of Manhattan. But in this small room

It has a mass equivalent to 11 suns.

In another galaxy called M33,

There is a black hole 58 miles across

It packs as much mass as 15.7 suns.

Next is an intermediate-mass black hole,

in this way.

At 1,460 miles across,

It's big enough to stretch from Florida to Maine.

and after some calculations

It contains the mass of 400 suns.

at this point

The black hole is starting to get much bigger than Earth,

but it's still nothing

Considering the sheer volume they carry. For example, this black hole.

Almost twice the size of Jupiter

Spanning an area approximately 172,000 miles wide,

But its mass is equivalent to her 47,000 Suns.

But these black holes are nothing

Compared to supermassive black holes,

Like Sagittarius A*,

Lives in the center of our Milky Way.

It covers an area about 14.6 million miles wide.

About 168 times the diameter of Jupiter

Same amount of mass inside

Than four million suns together. Well that may sound loud

But Sagittarius A* is small

compared to other supermassive black holes

take the one in the middle of our neighbor

andromeda galaxy,

516 million miles in diameter,

larger than the orbit of Jupiter,

and contains sufficient mass

140 million suns.

we finally get

Some of the largest black holes in the universe,

Still we have not reached anything

It exceeds the size of our solar system.

Let's take a look at supermassive black holes

Center of the Sombrero Galaxy.

2 billion miles in diameter,

Therefore, it will extend further than the orbit of Uranus.

It has about the same mass as 660 million suns. And the supermassive black hole at the center of Messier 87

So huge that astronomers can see it

From 55 million light years away.

that's 24 billion miles

contains the same mass as

6 1/2 billion sun.

However, this supermassive black hole is so large that

could still fit in our solar system

There is enough space.

So he should focus on one of the most massive.

of all supermassive black holes.

It's about 78 billion miles in diameter. In perspective, it's about 40% of the size

According to some estimates, our solar system.

and it is appreciated

About 21 billion times the mass of the Sun.

so you have it

Black holes could be millions of times bigger

Small like the sun or planets, or like cities.

It all depends on the mass there is.

I know it's going to be a universe,

It's not just size that matters.
