What is the Universe?
The universe is formed by a huge number of galaxies with their planets, stars, plasma, gas, dust. It includes absolutely everything that exists, both identified, and not identified until that moment. If we talk from the point of view of modern science, the existence of something outside the universe is considered meaningless. In practice, the Universe is usually understood as a particle of the material world, which is accessible to study with the help of natural science methods.
What is it - the universe
- Multidimensional. It should be noted that the existing multidimensionality of the Universe, in the form discussed by cosmologists, can manifest itself only within the framework of very high-energy factors - black holes, big bangs, bursters.
- Expanding. Expansion of the universe was launched simultaneously with the Big Bang. This state of her, for a two-dimensional situation, illustrated the surface of an inflatable rubber ball with dots that are applied to it — extragalactic objects.
It is possible to find out what the Universe is in books, on the Internet, and in scientific publications, but it is impossible to reveal the full objective concept of this word.
Generally speaking, what the Universe is, we can say that this is the world where we live. And not a city, a house, a country, but a world in the general sense of the word - a space that includes everything from crumbs on the floor to the furthest star, the existence of which we don’t know. We walk only on an insignificant, downright microscopic particle of the Universe, which is called the Earth. Compared to its size, and it is infinite, even our Galaxy is just a tiny speck of dust. Scientists assume that even such a distance is nothing in the Universe, because it is infinite, no matter how difficult it would be to understand. However, they say that someday all the matter of the whole Universe will gather in a single point.
