word "universe" is known to all from early childhood.That's it, we remember when raising his head and holding his breath, looking at the vast sky filled with stars sparks.We ask ourselves: "How infinite universe?Does it have a specific spatial boundaries, finally, is it possible to find the place in which the center of the universe? »
What is the universe
By this term is understood the diversity of the stars that can be seen not only by the naked eye, butand using optical devices such as a telescope.It comprises a set of galaxies.Since we can not yet see the universe completely, and its borders are inaccessible to our eyes.It may well be that it is infinite and all.It is also impossible to determine for sure its shape.Most often, it is presented in the form of a disk, but it may well turn out to be spherical and oval.And no less controversy arises around the question of where the center of the universe.
Where is the center of the universe
There are various theories to explain this concept.So, we can recall the theory of relativity: according to her center of the universe can be considered any point with respect to which the measurements are made.Over the years the human view on this issue has undergone major changes.It was once thought that it was the Earth - the center of the universe and all creation.According to the ancients, it was to have a flat shape and build on four elephants which in turn stand on a turtle.Later adopted the heliocentric model in which the center of the universe in the sun.And only then, when scientists realized that the Sun is just one of the stars of heaven, and not very big ideas about the center of the universe have come to the mind what we have today.
notion of the center of the universe in the Big Bang theory
so-called "Big Bang Theory" has been proposed throughout the astronomical community with Fred Hoyle - known physicist - as the explanation of the origin of the universe.Today, it is perhaps the most popular in various circles.According to this theory, the space, which now holds our universe was the result of a very fast, resembling an explosion, expansion of negligible initial volume.On the one hand, all human notions, such a model should not only have a well-defined borders, but also the center, which is located in the place from which, in fact, started the expansion.But there is a matter that people living in a limited three-dimensional space, it is simply impossible to imagine.So the point is that the astronomical center of the space may be in another, reach us measurement.
Research telescope «Hubble»
Recently in the media there were reports that the orbital telescope "Hubble" has made a series of pictures of the nucleus of our universe.And there was found a city in the center of the universe, from which the fan run up the galaxy.More to explore it is not yet possible, because it is located too far away.
Wherever point astronomical center of our universe, we do not can not only achieve it, but even just to see.
