If all of you have a desire in the universe , then many such questions must have come in your mind that what is the universe and what is it made of. At the same time, we also try to know what is in the universe . There are so many mysteries that scientists do not even have the answer to.
In this article today we will know everything from the beginning to the end of the universe . As well as his unsolved mysteries, so let's start .

Universe (Universe in Hindi)
All that exists is the universe . If we say in the language of science, then the universe is made up of all the things present in space . Our earth, moon, planets, galaxies, solar system, black holes, stars are all part of them. Along with this you get to know about space.
space
The word space is used for the place where there is empty space of the universe . For example, the space between our Earth and Mars is called space. But this space is not really empty. In this, many substances like excessive dust and gas keep circling . You must know that both space and the universe are different. Because the universe is an object made up of everything, where space is the place of the universe . Let us now know how the universe was born .
How The Universe Was Born
Till now scientists do not have any such technology to go back in time to find out how the universe was born, but there is some theory developed by scientists from which we can know how the universe was born .
The most popular theory in this is Big Bang Theory . When there was nothing in the universe, or it can be said that this universe was not there. There was no existence of time and space then.
About 13.6 billion years ago, there was a point that was very hot and dense and very energetic. There was a very loud explosion in it and our beloved universe was born , then with this both time and space came into existence. Then the energy of that point started spreading all around and gradually our universe started to form. So now let us know further how the universe was formed after this .
How The Universe Formed
When our universe started expanding completely, it was so hot that it was impossible for anything to exist. There was energy all around. Then 1 second after the Big Bang , particles like protons and neutrons came into existence. Even if we were present at that time, we would not have been able to see anything, because the particles of light did not exist at that time. Without which it would have been impossible to see anything. Then in the next 3 minutes, the particles of light were born.
Similarly, as the universe cooled down, so did different types of particles . In the next 380,000 years , it cooled so much that a single atom was formed. It contains both electrons and protons . After 400 million years , again these particles joined together to form the first star . In this way many stars were formed and all of them together formed the galaxy . Friends, many planets were also created. About 9 billion years after the birth of the universe , our solar systemwas born. In which our own earth is built and we are living on it. So now we know what the universe is made of.
What did the Universe Consist Of?
About 30 years ago, scientists used to think that the universe is made up of only ordinary matter, but in reality there was no such thing, but some such things existed in the universe which we could not see . What were they, let's know next.
Ordinary Matter
Ordinary matter that we see around us. Of whom we are made. From whom this earth was made. Our Moon, all the planets, galaxies and whatever we see in the universe are made of Ordinary Matter . Its quantity in the universe is only 4.6% .
Dark Matter
The particle that is not visible to us in the universe is dark matter . During the year 1930 , a scientist named Fritz Zwicky was doing an exercise of the motion of the Galaxy Cluster . They observed that the speed of the Galaxy cluster that was closer to the center and the speed of the Galaxy on the outer edges of the cluster was almost the same, but this was absolutely impossible. The mass of this galaxy was not so much that the gravitational force generated by it could keep the galaxy at the edges connected.
By this time, the stars of those galaxies should have been thrown out of this group, but this was not happening. This meant that there is some invisible substance which is generating so much gravitational force and is binding these entire galaxies , but we did not know anything about this matter and neither we were able to see it. For this reason it was named Dark Matter . Its quantity in our universe is 26.4% .
Dark Energy
According to the law of gravitational force , everything in the universe, molecules , atoms, planets and galaxies generates the gravitational force . Due to which all the things generate a pull towards each other .
In the year 1929 , due to the research done on a supernova living in a Galaxy , we came to know that our universe is expanding day by day . One thing is absolutely certain from this that due to the force of gravity , the speed of its spread will slow down over time, which was completely natural. Because the universe was expanding towards the Baharo and the gravitational force was being generated inward, but then in the year 1998 , two teams of scientists separately tested the supernova of the Galaxy . In this test that supernovaHe was farther than he should have been. From this the scientists came to know that today the speed of expansion of the universe is more than in the past. This meant that our cosmic speed was increasing continuously , but how could this happen? It should have slowed down because of the force of gravity . It means that there is definitely some mysterious force which is spreading our universe .
At that time , no scientist could understand this secret of the universe , that is why it was named Dark Energy to solve that thing. Its quantity in the universe is 69% . So finally understood that our lovely universe is made up of all the things . Would you like to know what is the size of our universe , so let us also know this.
What is the size of the universe
We did not know, what is the size of the universe , but from its density we can guess, if the value of the density of the universe is more than 1, then its shape will be like the shape of a closed sphere . Exactly like our earth. This means that our universe will not have any edge or edge. But it won't be the end either. Because if the value of density is less than 1 then we will see it spreading outwards. If the value of density is 1 then the size of the universe will be flat. It will always spread and there will be no limit to it.
We are aware of some questions. (Question about universe in hindi)
Q-1 How old is our universe?
Our universe is 13.6 billion years old. Which is the time from Big Bang till today.Q-2 How will this universe end?
After a while the speed of expansion of the universe will slow down completely and due to the force of gravity it will again merge into one point.By the way, there are many possibilities of the end of the universe, which you can know here (must read it once)
1. Great contraction
2. Great expansion
3. Great cooling
4. Others tooQ-3 When and how did the universe begin?
The universe began with the Big Bang event about 13.6 billion years ago.Q-4 Which is the largest galaxy of the universe?
The largest galaxy in the universe is ic 1101. The number of stars inside it is believed to be 1,000 billion. Which is about 3 times more massive than our galaxy
Now it is the turn of the unsolved mysteries of the universe . Such secrets which we do not know but are very curious to know.
Mystery of universe
The question of what is outside the universe is no less than a mystery. Our universe spans over 96 billion years . Even as far as we have access. We have not been able to see what is ahead of it, nor do we know whether the universe is in front of it or any empty space. If some theories are to be believed, there is another universe outside space . That is, Multiverse, if this is true, then in reality you do not know how big this universe will be .
Parallel Universe
Till now we have not found any proof of existence of parallel universe . But if we follow the rules of maths and science, it is possible. Such a universe which is similar to our universe but other events are happening there. Like if you are a doctor in this universe , you will be an engineer in that universe . This is a wonderful thing.
aliens in the universe
It is as simple as it is difficult to answer this, there are more than 100 billion galaxies in our universe and there are 200-400 billion stars in each of them. These stars have many planets.
Who is called Tara (who is star)
When an object has its own energy and its own light, then we can call it a star , the Sun is a star but the Moon is not a star . Because the sun has its own energy and its own light, but the moon has neither its own light nor energy , the moon is visible to us from the light of the sun, after all you must have known from the earth what a star is.

So is it not possible that there should be no life on any of these many planets ? There must be aliens in such a vast universe, this information was given to us by a scientist through Fermi Paradox .

What Was There Before In The Universe?
The answer is not possible yet. Because whatever you are seeing was created before birth. Before the universe there was neither time nor space . So it's almost impossible to know. It is believed that there must have been a universe before us . Which was joined by one point and then this new universe of ours was born due to the explosion of Big Bang , now you would like to know about the strange things of the universe .Strange Things Of The Universe
Very strange things have come in our universe and one of them is Antimatter , so let's know further.
Antimatter _
Just like there is white color against black. In the same way the particle has an antimatter . The electronegativity of the proton residing in the center of the particle is positive (+) and the electron residing around this center is negative (-) . But when it comes to antimatter , it is the opposite. The electronegativity of the proton in the center becomes negative (-) and the electron moving around becomes positive (+).
There is a lot of energy in this antimatter . With about 10 grams of this quantity, we can also send the vehicle to Mars . But the problem in this is that its quantity in the universe is almost negligible. Now the other strange thing which is there are black holes .
Black Hole
The black holes that are there are no less than a mystery. It is the demon of the universe who completely swallows everything that comes in its way. Even light is not allowed to pass through. Because their gravitational force is very high. That's why we can't see them. When a growing star dies, a black hole is born. We have not yet been able to find out what happens at its center. If I tell you that if you check the mass of a teaspoon of a black hole, it will be found to be equal to the weight of 10 elephants.
So this was just some amazing information related to the universe , so give me permission and how did you like this information , definitely tell in the comment, share it with your friends on social media like WhatsApp , Facebook from which they can also get this information.
