Where did the universe come from?

Theories and hypotheses about the origin of the universe -a huge number, they are all different and all as one answer the question: "Where did the universe come from?". The most interesting thing is that by considering one theory, analyzing it, you become its supporter, until you turn to the study of another theory, which, in turn, convinces you of your own rightness - and so on without end. Perhaps people will not soon be able to find the right answer to the question of where the universe came from.

If we take the oldest theory of originThe universe, then, in accordance with the undeniable for many sources - the Bible - the world was created by the Creator approximately in 5508 before the birth of Christ. This theological hypothesis of the origin of the world is fairly well known, but it is held mainly by clergymen and especially religious people. Scientists who question everything and everything, including the existence of God, naturally have a different idea of ​​the origin of the world.

If you look at the explanatory dictionary, the Universe -it is a system of the universe, which includes all the cosmic space and the celestial bodies that are in it. An alternative definition of the universe is the "cluster of stars and galaxies".

The most common scientific hypothesis, explaining where the universe came from, is the theory of the "Big Bang".

In accordance with it, approximately 20 billion. years ago the whole universe was substituting a very small substance, the size of which is less than a grain of sand. However, despite the tiny dimensions, the density of this substance was enormous: about 1100 g / cm3. Of course, there were no stars, no planets, no galaxies to which we were accustomed, but it was an embryo that could potentially create all this diversity of celestial bodies. This substance can be compared to a small seed, from which a powerful and branching tree subsequently grows.

It is because of the high density of the original substance that an explosion occurred that divided this smallest particle into billions of smaller particles - the universe subsequently emerged from them.

There is another hypothesis about a large explosion,responding to the question of where the universe came from. In principle, the essence of these two theories is almost identical, except that in this hypothesis, instead of the substance from which the universe appeared, a physical vacuum appears. That is, the whole world was due to an explosion in a vacuum environment.

Vacuum in Latin means "emptiness", butThe meaning of this concept is much broader: a vacuum is not a void in the conventional sense of the word, but a state in which all things are hidden and potentially contained. Vacuum has the property of changing its structure - just as water turns into ice or steam. In the process of changing this structure, an explosion occurred, which caused the birth of the universe.

In addition to theological and scientific hypotheses,explaining where the universe came from, there is also a scientific-philosophical point of view on this problem. She considers the possibility of creating the universe in principle a sort of higher intelligent principle. Such a theory implies that the world did not always exist: it has its own starting point, even more - the entire universe is constantly evolving and growing.

This conclusion was reached by scientists studying the composition andthe glow of stars. So, in the 30s of the XX century, when studying the Milky Way, it was found that the light emitted by the stars is shifted to the red region of the spectrum. The farther the distance from us to the star, the more this shift is more pronounced. It is this observation that gave scientists information that the universe is constantly expanding.

The second scientific fact, which confirmed the developmentThe universe became the "death" of the stars. Based on the chemical composition of the star, its body consists of hydrogen, which constantly participates in various reactions, turning into heavier elements. When hydrogen is depleted, the star "dies". According to some theories, all the planets of our system can be the result of "death" of stars.

This discovery gave grounds for one more conclusion: since the decomposition of hydrogen is a natural and irreversible process, the Universe naturally and gradually moves to its end.
