cosmogony
The origins and beginnings of the universe continue to be a great mystery for researchers and scientists alike. How did the stars, the earth and other planets form? How is it going in a tight time system? And what is the relationship that makes the planets float in this form in a vacuum that we know only a few information, and where all these materials that worked on the creation of planets and the earth and the air we breathe, all these questions took place in the minds of many of the old and current scientists, Scientific missions into space to study space materials Perhaps the tip of the thread that leads to the discovery of the origin of the universe may be found
Big Bang Theory
This theory states that the whole universe was a large block of heat and material molten and consisting of atoms of hydrogen and helium, lithium, and with the passage of time exploded these materials, leading to the formation of many objects blown away from the center of the explosion, and when cooled objects volatiles led to the formation of planets and stars in its current form, as the result of other elements, such as following the explosion known such as hydrogen, helium and oxygen gases, and is known as the physical laws, there is a strong attraction between objects and thus the celestial objects like moons orbiting the planet has a stronger attraction like Earth, and as a result of his Its laws consisted of various galaxies, which we do not know them except the Milky Way, the Big Bang passed through several stages as follows
The first stage
This stage is called zero absolute, that is, the time does not exist, and therefore the known physical laws do not apply to this situation, and then the universe Is a tiny atom that is much smaller than the diameter of the nucleus of the atom
The second phase
It begins with the formation of time by one second, when the temperature of the universe is estimated at 10 32, which is much higher than the temperature of the sun much, and it is known that the atom is governed by many threads such as nuclear bond, To the amount of 10 cm
third level
It is a period of two to three minutes. At that time, photons and electrons formed. As a result of the universe's inflation, the temperature began to drop to 10 billion degrees Celsius, at which temperature the helium is formed
The fourth stage
Its duration was estimated from 3 to 100 million years. In this period, the hydrogen atoms began to appear and formed as a result of the temperature cooler that allows the formation of this element. The neutral atoms and the known gases
level five
Is considered after the third stage to the present time, and at this stage formed stars and asteroids, and based on the theory of expansion began to expand the universe and away from each other, forming the current solar groups and galaxies
