What A Black Hole It Is!

Strange. It's the first word you guys think when you know that there's a hole colored black in space, isn't it? Yeah, black hole it is. But what is a black hole? And where do black holes come from?

Black holes are soo strong

Nothing can escape from a black hole because its gravity is so strong–not even light. Gravity is a force that pulls one thing to another. Gravity is the force that holds you down on Earth. When you jump up, Earth’s gravity pulls you right back down. Earth’s gravity also makes the Moon orbit (go around) Earth.

The more matter (stuff) that is packed in a star, planet, moon, or other object, the stronger is its gravity. Gravity makes an object with more matter pull an object with less matter toward it. The Sun has a lot more matter than Earth. The Sun’s gravity pulls on Earth. It makes Earth orbit the Sun.

Matter is packed very tightly in some things and loosely in others. The matter that makes up an iron ball is packed much tighter than the matter that makes up a bag of feathers. A scientist would say that an iron ball is much denser than a bag of feathers.

A black hole is denser than anything you could imagine. A black hole could have a million times more stuff than our Sun. All of this stuff would be packed into an area smaller than a city. The force of gravity from so much stuff packed into such a small area is awesome.

Where do black holes come from?

Astronomers and physicists think black holes come from dying stars. A dying star burns out and stops shining. All the stuff that makes up the star starts falling in on itself. The star gets denser and denser. If the star is big enough and has enough matter, it could get dense enough to become a black hole.

Let me clarify with the details.

1. A star begins its life as a cloud of dust and gas known as nebula.

2. If the dust and gas of a nebula get close enough together, gravity pulls them into a giant spinning ball.

3. As the ball spins, it gets hotter and more tightly packed, leading to the birth of a protostar. Eventually, nuclear fusion–in which two atoms fuse together to form another type of atoms–begins. Here, hydrogen atoms fuse together to form helium. Nuclear fusion releases huge amounts of energy that fuels a star throughout its life.

4. A protostar becomes a star when it reaches a temperature of 18 million degrees Fahrenheit (10 million degrees Celcius). Then, the star begins to shine.

5. A star turns into a red giant when its hydrogen fuel begins to run out. The star's core shrinks and the outer layers expand, cool, and become less bright. A red giant glows with a red color.

6. A red giant can change into the next step depending on its size. A small to medium sized star–one that is up to eight times the mass of the Sun–becomes a white dwarf. It forms when the star uses up its fuel and collapses. A white dwarf is very dense–a spoonful of its core can weigh as much as a dump truck. White dwarfs continue to glow because of energy trapped in their core.

While a very massive star–one that is more than eight times the mass of the Sun–becomes a supernova. It occurs when the star uses up its fuel and collapses under its own weight. This collapse leads to an explosion that sends a shock wave through space. The supernova may completely destroy the star, or it may leave the core of the star intact.

7. A supernova can change again depending on its size too. The core of a star that has undergone a supernova forms a neutron star. The atoms in the star condense and collapse until two of the particles that compose atoms, protons and electrons, fuse to form neutrons, another type of atomic particle. Neutron stars have the highest density of any type of star–a teaspoonful of the star's crust would weigh ten billion tons on the surface of the Earth.

And when an extremely massive star undergoes a supernova, the remaining core shrinks and eventually collapses completely. The collapsed core forms a black hole, which has such a strong pull of gravity that nothing can escape it, not even light.


Imagination

Phew. How dark it is! Now, look at this.

Imagine you are an astronaut. Then you are given a task to go to space to complete a mission. When you're in space, and you're taking the full control of the spacecraft where you're in it, you suddenly get amnesia and forget every button in the pilot cabin. Nobody can control the spacecraft except you. You then press any button and unintentionally press the light-speed button. The spacecraft blast off with that speed till the spacecraft stops, as though it goes darker and darker. But you think of a 'how can a spacecraft with speed of light stopped'-thought. The only answer is black hole. And when you're sucked up to that blackened entity, what do you think you're going to?

a. To the death
b. To a dark world without light
c. To another dimension of world
d. To another place on Earth with different time/era
e. To another world containing non-human creatures a.k.a aliens
f. To another life-enabled planet besides Earth which also contains humans
g. Your own answer, is to …
