Our universe is very big. And so much has increased.
That we will never even imagine it. And this is also a huge challenge for us. In this great universe, our earth is smaller than a small particle. There is too much light on the Kanhi in such a vast universe. So somewhere very dark is there. The temperature is up to crores of degrees Celsius somewhere. So somewhere very cold too. It is too cold that no idea can be made. It's cold so much. Which is much more cold than ice. And in such an enormous and vast universe, there are also very powerful planets or stars from our sun. And in this universe there are very cold planets also from snow and life is possible in many places in the universe. Something like this is there. On which we can not think of living our life. Because that place is so dangerous that we will never die before reaching the place, and we can never go anywhere beyond that place.
When we talk about the universe,
we must know that the universe is of two types. One is the visible universe and an invisible universe scene that is the universe. Which we can see. And whose surgeon is the primary raw material of Big Bang. The planet, stars, meteors, galaxy, nebulae, black body, light, speed, time, gravity etc. invisible universe is called that place. Which is in place outside our universe. And he never sees us. That place is called Invisible Universe. What is in the unknown invisible universe outside of the boundaries of Brahmin on our part. They do not know anyone. Light years are used to measure such a large extent of the invisible universe. And light is the thing to measure the distance of the universe.

The way we measure the distance on the earth in kilometers or miles.
Similarly, the light year is used to measure the distance of the universe. And the distance covered in 1 year determines the light year. He is called a light year. According to this, we cut a distance of 9.5 billion billion kilometers in 1 year, according to which it cuts the distance of approximately 3 lakh kilometers in a second. And this 9.5 thousand billion kilometers is said to be a light year. Born from the Big Bang, the universe is in the distance of 93 billion light.
You must be thinking
of this fact that when our universe is 13.5 billion years old, then why is its expansion so high? How can it expand 93 billion light years, but if we give you complete information about it, then this post will be very big and you will not understand it well. So we will definitely tell you about it in a separate post. But our visual universe spreads into the expanses of 93 billion light years in what is in the invisible universe. No one has been able to find it till date and we have not been able to find any kind of information till date. So in this post we are giving you information about the origin of our visual universe here only. Later in the separate post about the invisible universe,

I will give you the informationIn 1927 Georges Lemaitre uncovered a paper published in Belgium. In the case of an expanded universe, a solution of common relativity equations was provided without knowledge, in 1922 Russian Alexander Friedman had done his compounds without compound. But Friedman was primarily interested in an ideal class of mathematics (including extending extensiveness and contracting) and did not move the prospect forward. That these can actually be described in the physical universe. In contrast, Lemaitre saw the problem of cosmology completely physically. And it felt that their solution predicted the expansion of the real universe of galaxies. The suggestion was started.
The composition of the universe -
Georges Lemaître created an equation named Friedmann Lemaitre Robertson Walker, based on Albert Einstein & # 39; s Theory of General Relativity. According to them, the origin of the universe was from a primary atom and the universe was formed with a great explosion. And if the substances of the universe began to move away from each other, the theories of Lemaitre were mocked in the early days. The most reprehensible scientist of this theory of Lemaitre was Fred Hoyle.

According to the theory
of Hoyle, the objects of the universe are not going away from each other. Rather, new substances are being installed between them. Which is called black matter. He revealed the Fred Hoyle model theory and lamited the theory of Lemaître as Big Bang Idea, for a long time the scientists of the world were divided between these two principles. But as time passed. Well by the way scientific experiments proved this. The key to Lemaître's Big Bang theory is that he was denying his earlier words. He later understood this very easily. In 1965, the discovery of cosmic microwave background gave Lemaître's Big Bang theory the most recognized theory of status. Today, Lemaître's Big Bang theory is considered to be the most recognized theory of the universe.
According to the Big Bang Theory,
about 13.5 billion years ago all the atoms of the universe were atom and others. All those nearby were in one place, all the visible universes which we are seeing today. She was located in a small point. And at that time, according to the Big Bang theory, about 13.5 billion years ago, all the atoms of the universe were atom and others. All of those nearby were in one place. Suppose all the visible universe is what we are seeing today. She was located in a small point. And at that time that point would have been very dense and very hot. There are no rules of physics on this condition. There was no existence of space and time even in this state. There was an explosion suddenly due to some unknown reason. By which the universe was born. And the universe began to expand.

All the objects of the universe
began to move away from each other and this explosion would be called the Big Bang and would be extremely hot. This is the situation. Where no rules of physics work, in this state there was no existence of space and time. There was a sudden explosion for some reason in that situation. By which the universe was formed. And the universe began to be formed. All the substances of the universe started moving away from each other. This explosion is called the Big Bang. Now this question will surely come to your mind.
When that powerful explosion happened then how much heat would be in the universe or how much temperature it would be at that time. At that time the temperature of the universe was 141,679,000,000,000,000,000,000,000,000,000,000,000 how much temperature was in the universe at that time. It is also almost impossible to calculate. And after this so powerful explosion, less than 1 micro second is called blank time. In such a short time the temperature of the universe fell down very quickly and 1 micro was the second, then the universe reached 10,000 billion.
When the universe exploded then At that time,
everything was in the darkness. At that time there was no light of any kind. But you must be thinking this. That was why there was no light when such an explosion occurred. Because the Brahmand was in plasma state and the universe was not any molecule. And that was why there was no light, and in the same way it continued for 3.80 million years in the Dark Universe. And in this darkness only the protons and neutrons were formed in the universe, and by meeting protons and neutrons, the first molecule in the universe arose which was hydrogen. And hydrogen has great importance in the creation of the universe. Because the presence of hydrogen and hydrogen due to gravity began to form helium molecules. And then the universe got its first star i.e. sun and in this way gradually the stars became more and more stars in the universe. And in this way, the first light in the universe happened and the darkness was over in this way. And about 4 million years after the Big Bang, there was light in the universe.

And in this way
gradually after the cosmic matter emerged from the Big Bang in the universe and other comets, meteors, planets and celestial bodies began to form, for about 8 billion years, these molecules were created and ended in the universe. And in a similar way, our Sun and the Solar System were built around 4.5 billion years ago today. In which our earth was involved, along with the Sun, Earth was also formed 4.5 billion years ago. And when the earth was created for the first time, it was not at all exactly like today's time. It was a very hot fire. And at that time if it was seen then it could not be estimated. That life will ever be possible even on this. And he used to rotate very fast on his own axis. And at that time the day used to be just 8 hours. And there was no way to see the water on earth.
But there was steam in the air on the earth.
And many elements like H2O were present. The way the universe was formed and after that its temperature dropped very rapidly, similarly the gradual declines in the earth's temperature and the vapor in the air over the earth began to rain and it would last for millions of years. Hui. Due to this rain the river started becoming a reservoir and ocean. And after that, slowly, about 3.5 billion years ago, life began to flourish with the presence of hydrogen oxygen and carbon in water. And on earth became its monozygous organisms which were paramysium and amoeba. And due to these small bacteria, they gradually started making multi-cellular bacteria. And gradually the creatures on earth are full of animals. And life began to grow on earth.
