What is a Black hole? Mysteries and facts of black hole


 The universe is everything that exists planets,stars,galaxies,and space between them.Universe was formed 13.4 billion years ago with a single large explosion called BIG BANG.There after many changes have been occured since the formation of universe.4.5 billion years ago with dust,and rocky particles earth and other stars,planets,asteroids etc are formed.No one knows how big the universe is and what does it contains. According to many scientists we just know about 5% of matter in our universe,rest of that is mystery or filled with dark matter.There are many interesting things and some scary things.Black hole is a part in it.

Many of us know about black hole,but doesn't know completely about it.so in this post we try to investigate about the black hole.So this is the list of topics which we are going to discuss:

1.What is black hole? 

2.Types of Black holes?

3.singularity and event horizon?

4.what is inside black hole?

5.How does black hole work?

6.Is black hole connected to multiverse?

7.Will our sun become a black hole? 

8.what happens if we fall into a black hole?

9.is there any Black holes near to our earth?

1.What is Black hole?

What is a Black hole? Mysteries and facts of black hole

A Black hole is Possibly the strangest and mysterious object in the universe. It is one of the most mysterious thing that ever had seen and invented.It is a region of space where the matter and everything is collapsed in on itself.No one has ever seen it,but we can see black hole by a huge telescope.

Every thing which comes near to it will be attracted towards it .This results in a huge amount of mass being concentrated or compressed in a very small area.Black holes continuosly release a jet of radition.All this things happens because of gravity. The gravitational pull of black hole is so strong that nothing can escape from it not even light which travles at a speed of 300000000 meter per second!All the matter that fall into a black hole piles up to a single point in the centre,called singularity.

There may be as many as 1000 billion black holes in our univerese alone which aren't discovered till now. Every hour a 1 to 5 black holes are created!


2.Types of Black holes?

What is a Black hole? Mysteries and facts of black hole

Black holes are divided into 4 types depending on their energy and size.Black holes come in many sizes.Some are just few times more massive than our sun.Others found at the center of galaxies,may be millions of times more massive. Some has low gravitational pull but some black holes has million of tons of gravitational pull. Let us know about them.

Super massive black holes

What is a Black hole? Mysteries and facts of black hole


This black holes are the most powerful black holes and the heaviest black holes ever.According to many scientists, Most of the galaxies including our milky way,andromeda etc are believed to contain a super massive black holes at their center and it has been proved by scientists. This super massive black holes will easily pull anything within a 0.00001 seconds or lesser than that!Many theories have been proposed on the formation of super massive black holes.

The most popular theories are ,at beginning these black holes are very small and then grow gradually by pulling everything nearby it.another theory is when a lot of material is squeezed togethet in the center of a newly forming galaxies. These black holes normally weigh about a trillions of solar masses!

Stellar mass black holes

What is a Black hole? Mysteries and facts of black hole

Stellar mass black holes are the 3rd heaviest black holes.Stellar mass black holes are formed by the gravitational collapse of a star as a hyper nova explosion or gamma ray burst.These black holes are also known as Collapsors. Stellar mass black holes has a mass of more than 10 solar masses( solar mass is a used calculate mass of celestial objects and it is equal to the mass of sun and 1 solar mass= 2×10000000000000000000000000000000 kg or 2× 10'30).

Intermediate-mass black hole

What is a Black hole? Mysteries and facts of black hole

These black holes are also one of the heaviest black holes with a mass range of 100 to 1000000 solar masses! There are many proofs for this IMBH.The strongest proof for IMBH comes from a low luminosity active galactic nuclei.The region which is near to this IMBH is totally dark.10 IMBH evidences have been recorded  while they are releasing x-rays.

Miiniature or mini black holes

What is a Black hole? Mysteries and facts of black hole

These are the smallest black holes in the black hole family.These black holes are popularly known as Quantum mechanical black holes or mini black holes. Quantum mechanical effects play an important role in this micro black holes. this black holes were invented by stephen hawking. These black holes are weak and can easily evaporate when compared to others.The radiation released by this black holes couldn't damage our earth.


3.singularity and Event horizon

What is a Black hole? Mysteries and facts of black hole

Singularity and the event horizon are the most important things in the black hole and one of the mysterious things in the universe.The theories of Science and time doesn't work here  Totally science and time goes crazy in this.
It is very hard to understand about this but let me explain you in a simple way
Gravitational Singularity or singularity   is the centre part of the black hole and a one dimensional point,where trillions of kilograms of mass is stored in a negligible small  size!

This happens because of gravity, density,space and time curves becomes infinity.In the singularity the time stops for the person who fell into black hole.

While the Event Horizon  is the boundary region of the space surrounding the black hole from which nothing can escape.This event horizon is the reason for which we cant see the singularity. science cant work after crossing this event horizon.In 1974 the event horizon was first invented.

4.What is inside a black hole?

What is a Black hole? Mysteries and facts of black hole

Well its the most mysterious question in the world.The things which are happening in the black hole are completely beyond our science and ideas.We just know 0.1% about the black hole in which we already know  two things in the black hole which are singularity and event horizon.But remaining 99.9% is totally mystery and covered with darkness.There are number of theories based on what is inside a black hole,But no one knows the perfect answer.
Some of the famous theories are like it is connected to a multiverse or it is operated by aliens etc.There are many thing which are collapsed into it but no one knows where does that matter is.If the matter is crushed or highly compressed there should remain some particles but there are no particles near a black hole .One of the main reason for which we cant see it is darkness or dark matter.Everything which is pulled by black holes is no more matter.

5.How does black hole work?

What is a Black hole? Mysteries and facts of black hole

Do you know about how black hole works?Most of us doesn't know about it.We know that how black hole forms.But After Formation of Black holes It keep expanding by pulling everything nearby by it.Black holes and Humans has similar qualities like when we are kids we had More energy and used to play all the day same like that black holes are very powerful when it is formed but after it starts getting weaker just like humans.Black holes are 100000x more gravity than on our earth.It takes a million and billions of years for a black hole to end.Black holes can produce a deeper sounds. Stephen hawking, the scientist who worked on Black holes wrote a book on black holes. 

6.Is blackhole connected to multiverse?

What is a Black hole? Mysteries and facts of black hole

The most mysterious question about black hole is its connection to the multiverse.As we dont know what is inside a black hole, many questions raised in the scientists minds and also in your mind. Apart from them,the most acceptable reason is multiverse.Blackhole is completely black in colour. No one has ever went inside to it.According to great scientists theories, and in some movies the black holes connects to the many universes.
Black hole quickly and easily attract the things.at that your speed can be at 1000000m/s which is quite near to light speed.So at that speed you can travel long distances in a short period of time.That means you can travel from one universe to other universe. 

7.will our sun turn into a blackhole?

What is a Black hole? Mysteries and facts of black hole



The most worried thing about our sun is that turning into a black hole.Many researches have been done on this question. Atlast in the late 1990's scientists had given a clarity about that.A star has different life cycle.let us know them

1.stellar nebula <Average star <Red giant < planetary nebula <white dwarf

2.stellar nebula <massive star < Red supergiant < supernova < neutron star or black hole.

Now,guess ourn sun's life cycle.

If you guessed the 1st option then you are right.

Approximately 4.5 billion years ago our sun was formed.

According to scientists, our sun is about to live for 14 billion years.as i mentioned above life cycles,now our sun is a average star.In between 6 to 9.5 billion years our sun starts getting warmer and warmer.It starts running out of fuel.After 5.5 billion years from right now,our sun will become a red giant sun.The people who living at that time can't bear the amount of heat.

After 1 billion year of getting warmer,our sun will turn as a planetary nebula.In planetary nebula stage,our sun will lose its outer layer and gas.

Then our sun starts getting smaller and smaller.

After 9.5 billion years from right now,our sun will become a white dwarf.Our sun and earth will be in the same size.our sun will cool down.It will be the last days for our sun.

So,now i think you got the point.
Our sun will become a white dwarf instead of black hole.


8.what happens if we fell into a blackhole?

What is a Black hole? Mysteries and facts of black hole

If you fell into a black hole, it would be a hell for you.You can't imagine that situation. When you get closer to a black hole.

What is a Black hole? Mysteries and facts of black hole

 First you doesnt feel anything like weird.By getting closer to it, you body starts stretching .When you get to close to it,then you will be stretched 100 times greater than your actual height.You will be seen as red in colour for other crewmates.The gravity will crush you.And then,atlast you will be disappeared.You will be died.These is no chance to escape from it.

9. Is there any Black holes near to our earth?


1.HR 6819

What is a Black hole? Mysteries and facts of black hole

This was the nearest black hole ever discovered  from our earth.This was discovered in the early 2020.This was discovered in the telescopium constellation. Its about 1000 light years from our earth. The coolest part from this black hole is that,we can see it through our naked eyes in the southern hemisphere. Firstly it was discovered with a 2.2m telescope.This black hole is also called as dark hole,because its totally dark and hiding behing a planet.

2.A0620-00, or V616 Monocerotis

What is a Black hole? Mysteries and facts of black hole

This black hole was discovered in 1975.This black hole is about 3500 light years away from the earth.This black hole is about 6.6 solar masses.
It was observed through x ray outbursted in 1975,but it initially outbursted in 1917.

There are many other black holes near to our earth.But we wont be affected with them.

Black hole is completely dark,so its not possible to find all black holes near to us.We just found few of them There are many black holes near to us.But we cant see them.

In this articles, we learned about what is black hole and some other main and important details. We wilk bring the latest updates about black hole in our blog.If you want to get notified just add your email in new letter option and hit the subscribe button.

I worked 3 days to write this article.I wanted to give you detailed information about black hole. For my hardwork,just share this to you friends So that they can know about it.I would feel more happy if you enter a comment about this article.
Have a nice day and be science master.
