what is big bang:

When the universe started? From whence came the universe ? For many years these questions have become a reason for scientists to lose sleep. In 1991, an interesting comment was made by author Fay Weldon in this regard by scandalous astronomers in an irritating (!) Magazine - 'Who cares about half a second after the big bang' or even a little back, 'What about half a second before '? What was true Generally speaking, there is nothing to say about the 'half-second' of the answer to the answer.

The joke is, if we have to answer this question, we have to come up with another question, how do we know that the existence of the universe was not for an infinite period of time? Most scientists reject the idea of ​​an eternal universe, due to the second formula of thermodynamics. In the words of the white word, Entropy is increasing in time with each process. Applying this formula to know the nature of the universe, it was found that our current universe continued to embrace a transition of final chaos through one-way. But if the universe had existed for a long time, then infinity would not have existed as of now. In addition, the Sun and Sun-like stars are constantly absorbing the energy stored in the universe, and in one-way process, If the universe remains in existence for a period of time, then this specific amount of energy will be exhausted. But in reality it is not.

As a direct proof of the origin of the origin of Brahmand, the three major observational causes of the original Bangabandhu are said to be that the main and the first thing is that our universe is continuously being integrated. The second is the existence of a common thermodynamic radiation spreading all over the universe, which in turn explains the depletion of superheated heat produced at the time of the Big Bang. And the third is the comparative mass of chemical elements and compounds spread in the universe that have been created by nuclear reactions at the highly concentrated phase in the aftermath of the Big Bang.

But along with these there are a few other small-and-a-half-quota questions. What caused the original explosion? Where is the blast? Where is the end of our universe? Why the Big Bang has not turned into a black hole? Questions might seem quite suitable for the Big Bang. But the truth is that these questions show an image of a big mistake about the Big Bang. So first of all, what is the significance of the universe's expansion? It does not necessarily mean that the galaxies are running away from each other due to the speed received from an explosion; Rather, the spaces between galaxies are being expanded.

And the place that can be compressed or expanded in such a way is a major conclusion of many experimental Einstein's general relativity theory. According to this decision, space span is not an indefinite fixed field, but a region influenced by gravity. This type of space geometry is called curvature. And curvature occurs when space and time are curved simultaneously by gravitational effects.

A very simple but small example may be when a balloon is blown with blowing, which has numerous foil or tint on it. When the balloon is in the flower, the distance between the stumps on the balloon continues to grow. In this case, we can assume that the drafts are as galaxies. But it should be remembered that in this example, the surface of the balloon is not just the size of the inner space of the balloon, in our expanding universe. So now if we look at the opposite, from the hollow balloon (at this stage the balloon should be in round rotation), step by step to its initial closeness, then the picture of the beginning of the universe may be slightly understood.

But this is the most important and complex aspect of the Big Bang theory. The key point of relativity theory is that space and time are part of the universe. These are not the backgrounds of any explanation where the universe itself is going on. So the origin of our mysterious universe certainly means the origin of space and time. Still, where can we find a source of origin? Then you have to do it again to relativity. He says that space and time can take some special forms. They are called Singularities and can be called 'Ekkata' in Bengal. As the existence of the same loneliness in the center of the black hole Another example might be that the situation at the time of the Big Bang was about the precocious condition of space. The idea is that as much as the time goes on, the universe will gradually shrink and the curvature of the space can be infinite with a single face, That would stop coming to a point to be straightforward. And just starting from this point is the beginning of time and place. Whenever this idea was accepted, there was no other meaning than what happened before the Big Bang;

Since the beginning of time, there was nothing before the Big Bang to the Big Bang. But there are some who do not keep this as some of those who make mistakes as a spaceship. But it's a terrible mistake. Since there was no place before the blast. Just so much that I have not written anything about what I wrote about it ... Then I started the famous legend of George Gamo's Big Bang ...

big bang:

The universe is a special theory of creation. According to this theory, the universe was created due to the explosion of a huge body at a time before 1500 billion years ago. In 1927, Georges Lemaître, the scientist of Belgium, first published this theory. It is well to be said that George Lamieter published this theory, but George Gaumo expanded this theory. According to Lemetre, in the beginning of creation, all the objects in the universe are accumulated in intercostration and become a large atom. The atom exploded after the universe was created. Edwin Hubble supports and explains this doctrine. Observe the Hubble observation that space galaxies are moving away from each other in a fixed speed. According to him, the galaxy was created due to the Big Bang in the beginning and the behavior of these movements supported the Big-Bank.

In this way, the existence of radiation that is due to the explosion can not be proved at first. As a result, there is a conflict among scientists about the matter. Arno Penzias in 1964. And two scientists, Robert Wilson, prove the existence of radiation. As a result, the idea of ​​Big Bang is well-established. So far this theory is considered to be true in the creation of the universe.

According to Big Bang theory, the mystery of creation of the universe -
Initially, space objects were spread in distortion. However, scientists can not explain how these original substances were created and how they were arranged. According to Big Bang theory - these scattered objects come to each other approximately 1500 billion years ago and gradually form an egg. Scientists named it Supper Atom. Note that no time and space existed at this time. The dense insertion of the fibers inside the amplitude of its infinite density led to its temperature - 10 ^ 18 degrees in the case of any measurable scale. The events that took place in the second one after the Big Bang were chronologically downgraded -

1 to 10.43 seconds : according to quantum sources, Big Bang's combination of 10.43 seconds [this time was called Planck epoch], there were four natural force coordinates. These balls are: strong nuclear force, weak nuclear force, power-magnetic force and gravitational force. All of them were created by a very large force.

Plank-10.35 seconds from the time of the end: The gravitational force, separated from the other three balls after the Planck expired . As a result of the gravitational power, the giant reached the highest contraction level. Then, in the case of concentration, the object was 5'10 + 93 grams per cubic centimeter per cylinder. The temperature of this time was 10 ^ 32 Kelvin. During the 10.35 seconds, this temperature stood at about 10 ^ 27 Kelvin. During this time, quark and lepton particles were created. It was created at the same time - some objects and antiparticles. After the collision between the object and its enigma, both types of objects are destroyed. As a result, only the quark and lepton remained.

10.35 to 10.10 seconds : In the next 10.10 seconds, the temperature dropped to 10 ^ 16 kelvin. When this temperature drops further, the weak nuclear force and the power-magnetic force separate. At this time, the quarks formed by the force of the vigorous force created photons, protons and neutrons. After 1 second: after 1 second the temperature drops to 10 ^ 10 kelvin. But the atomic mass was not possible at this temperature.

It is believed that the particles formed from 3 seconds to 100,000 years of Big Bang have become cool. Hydrogen and helium atoms are formed in this condition, combined with existing electrons, protons, and neutrons. In addition to these two substances, there were plenty of electron plasma with the electron plasma. All the huge gathering of the gathering was moving away from the center of the Big Bang at a speed of speed. At this time these particles were very hot. By the gradual they were cooling down and due to their inner intestines - they came closer. As a result, a large number of sub-components were able to form separate groups. The process of forming this separate group was created by the Galaxy (Galaxy). Our solar system is also inside this galaxy. This galaxy is called Milky Way.

When we look at the sky in the sky, it seems that the universe is so beautiful and how many variations are spreading in it. Everything in this universe is beautiful but its beauty will be increased if science is discovered within it.
