What is a Big Bang

What is a Big Bang

The soap opera with the similar name is watched by millions of TV viewers worldwide, however that, in effect, it is the Big Bang very few people reflect, the physics and astronomy is close to not everyone. Meanwhile, it is the main cosmological theory explaining origin of the Universe.

The theory of the Big Bang – sounds at the same time and romantically, and is frightening, and is trivial, and is scientific. What is this most Big Bang? How it occurred and how influenced emergence and formation of the Universe and what, after all, deserved such popularity?

Jared Leto's hero, Mutely, in the movie "Mister Nikto" reflects on this subject: "What was to the Big Bang? The fact is that was not any "to". To the Big Bang time did not exist. Time birth – result of expansion of the Universe". It is quite difficult for human mind to imagine that time could not exist that there could not be no in general nothing, and is constant in to the head spins a question: "At least the emptiness was?". But the fact is that according to the theory the Big Bang was not even emptiness.

To the Big Bang the Universe was in a so-called singular state, that is had the infinite density and temperature. About 13.7 billion years ago there was that explosion after which the Universe began to extend with an improbable speed. So quickly that from net energy the first subatomic particles which through many thousands of years turned into the first atoms – the smallest compound particles of matter began to arise. The main postulates of the theory of the Big Bang were formulated by Belgian Georges Lemetr. Strangely enough, Lemetr was at the same time both the scientist, and the priest. The basis of the theory of the Big Bang was formed by the theory of relativity which allowed to present development of the Universe from the very first timepoint, however to assume, the Universe at the initial stages how exactly developed, after all it is not possible yet. According to the theory, the Universe continues to extend constantly with a huge speed also now, but at once will extend so that will turn into a huge black hole, and then the Universe will return to a singular state again. By means of the theory of the Big Bang the scientists revealed a surprising paradox – is considered to be the Universe infinite, and, nevertheless, it of course. On the other hand, by scientists it was already proved that any infinity all the same of course. So, sooner or later the Universe will disappear again. However, it will occur only in case the average density of substance of the Universe exceeds critical, calculated in the theory. Only to calculate average density it is impossible to calculate. Whether there was a Big Bang actually? If was, how exactly it occurred and how our Universe developed? Whether waits for it the end, or it will exist eternally? And whether really the Universe is infinite? The theory gives questions much more, than answers, nevertheless, the modern science in many respects is based on it. However, there is in the world nothing more abstract, than the exact sciences which allow the person to develop and learn the world around it.
