The shape, device and dimensions of the universe

In cosmology, there is still no clear answer to the question that affects the age, shape and size of the universe, and there is also no consensus on its finiteness. Since if the universe is finite, then it must either contract or expand. In the event that it is infinite, many assumptions lose their meaning.

Back in 1744, the astronomer Zh. F. Shezot first doubted that the Universe Is infinite: if the number of stars has no boundaries, then why does not the sky sparkle and why is it dark? In 1823, G. Olbes argued the existence of the boundaries of the universe in that light traveling to the Earth from distant stars should become weaker because of the absorption by the substance that is in their path. But in this case, this substance itself must be heated and glowing no worse than any star. This assumption has been confirmed in modern science, which argues that the vacuum is "nothing", but at the same time it has real physical properties. Of course, vacuum absorption of the energy of photons leads to an increase in its temperature, which results in the fact that the vacuum becomes a secondary source of radiation. Therefore, if the dimensions of the universe are really infinite, then the light of stars that have reached the limiting distance has such a strong red shift that it begins to merge with the background (secondary) radiation of the vacuum.

At the same time, we can say that the size of the universe observed by mankind is finite, since the speed of light itself is finite . The distance of 24 Gigaparksex is the boundary of the light cosmic horizon. However, due to the fact that the speed of expansion of the universe increases, the end of the universe is at a distance of 93 billion light years.

The most important result of cosmology was the fact of the expansion of the universe. It was obtained by observing the redshift and then quantified according to Hubble's law. This led scientists to the conclusion that the Big Bang theory finds its confirmation. According to NASA, Which were obtained with the help of WMAP, the age of the universe, starting from the moment of the Big Bang, is 13.7 billion years. However, this result is possible only if we assume that the model that underlies the analysis is correct. Using other estimation methods, completely different data are obtained.

Touching the structure of the universe, we can not say about its form. Until now, not found that three-dimensional figure, which would best represent her image. This complexity is due to the fact that until now it is not exactly known whether the flat universe is flat. The second aspect is related to the fact that it is not known for certain about its multiple connectivity. Accordingly, if the dimensions of the universe are spatially limited, then when moving along a straight line and in any direction, you can end up at the starting point.

As we can see, technological progress has not yet reached the level to accurately answer questions about the age, structure and dimensions of the universe. So far, many theories in cosmology have not been confirmed, but they have not been refuted either.
