theories and hypotheses about the origin of the universe - a great many, they are all different and all as one answer to the question: "How did the universe?".Most interesting is that, considering one theory, analyzing it, you become a supporter until turning to the study of another theory, which, in turn, convinces their own right - and so on without end.Probably people will not soon be able to find the correct answer to the question of where did the universe.
If you take the most ancient theory of the origin of the universe, then, according to the undisputed source for many - the Bible - the world was created by the Creator about the year 5508 before Christ.This theological hypothesis of the origin of the world quite well known, but its hold, mainly members of the clergy and especially believers.Scientists also that cast doubt on everything, including the existence of God, of course, have a different view of the origin of the world.
If you look in the dictionary, then the universe - the universe is a system that includes all the space, and there are celestial bodies.An alternative definition of the universe - "a cluster of stars and galaxies."
most widespread scientific hypothesis to explain where it came from the universe, is the theory of "Big Bang".
According to it about 20 billion. Years ago the entire universe prepend a very little substance, smaller than a grain of sand.However, despite the tiny size, the density of this material was enormous: about 1100 g / cm3.Of course, in the matter it had no stars, no planets, no galaxies, to which we are accustomed, but the it represented a fetus, potentially able to create all this diversity of celestial bodies.This substance can be likened to a small seed from which later grows powerful and green tree.
Because of the high density of the original substance, an explosion occurred, which divided the tiny particles billions of smaller particles - have subsequently arisen, and the universe.
There is another hypothesis of the Big Bang, to answer the question, where did the universe.In principle, these two theories are almost identical, except that in this hypothesis instead of the substance, from which emerged the universe appears the physical vacuum.That is, the whole world was due to the explosion in the vacuum environment.
vacuum in Latin means "emptiness", but this concept is much broader: a vacuum - it is not a void in the conventional sense, but a condition in which the hidden and potentially contains all things.The vacuum has the ability to change its structure - just as the water turns to ice or steam.In the process of change of such a structure and an explosion that resulted in the birth of the universe.
addition to theological and scientific hypotheses to explain where it came from the universe, there is a scientific and philosophical point of view on this issue.It considers the possibility of establishing some higher universe reasonable basis.This theory assumes that the world has not always existed: it has its own starting point, even more so - the whole universe is constantly evolving and growing.
This is the conclusion scientists studying composition and shining stars.Thus, in the 30s of the twentieth century in the study of the Milky Way, it was found that the light emitted by stars is shifted to the red region of the spectrum.The farther the distance from us to the stars, so this bias is more pronounced.It is this observation has given scientists the information that the universe is constantly expanding.
second scientific fact, confirmed the development of the universe, was the "death" of the stars.Based on the chemical composition of the star, its body consists of hydrogen, which is always involved in various reactions, turning into heavier elements.When the hydrogen is exhausted, the star of "dying."According to some theories, all the planets of our system may be the result of "death" of the stars.
This discovery was the basis for a further withdrawal: since the collapse of hydrogen - a natural and irreversible process, the universe naturally and gradually moving towards its end.
