In minds of inhabitants the Universe and space are the words synonyms meaning a certain space outside the atmosphere. Such opinion is not deprived of a basis, but it not precisely. The Universe and space – concepts essentially different, united only by essence.
If to speak about the Universe, then it is correct to tell that it is set of everything that surrounds us and ourselves are people - including. The huge ocean and small points of planets, people and galaxies invisible to an eye, ugly molecules of viruses and microscopes, them studying – all this the Universe.
In the ancient time meant the whole world by the word "space", in the Middle Ages there was a concept of "microcosm" which was essence of the person, his inner world.
It is more difficult to give exact definition to space. For descriptive reasons it is possible to resort to east parable. Once the little small fish asked the wise sea queen: "What such Sea? All about it speak, but nobody can show me" what that answered: "You were born in the Sea, is surrounded with it and when you die, will be dissolved in it". Same it is possible to tell also about Space. Our house — Earth is surrounded with an immense scope of Space.
Primacy of life
The Universe and space conduct continued fight in minds of scientists that from them more initially. About emergence of life were speculated by people from time immemorial. The most known of hypotheses have a great number of the adherents arguing the point of view. One of the assumptions says that the Universe arose from emptiness as a result of a Big Bang. At present it represents constantly extending matter and galaxies depart from each other further and further.
Theories
The theory of the pulsing Universe says that the thought of emergence of life because of explosion covers only the certain site of time. According to this theory, space existed always and is life which interacts in itself and constantly develops. Our Universe is only one of space components, it is possible that only its small part.
There is an idea of space, as about chaos, meanwhile as the Universe an organized system, perhaps, having structure.
The Universe and space attract to themselves inquisitive minds of scientists at the state level. Billions of dollars are spent for studying the world surrounding us, research centers are under construction, more and more advanced aircraft are under construction. In spite of the fact that field of activity still remains huge, some success after all is achieved. Today each school student, unlike the medieval boy, knows that Earth round. What is taught at school now had to be defended at the price of the life in recent times as it was made by Copernicus.
