In cosmology, there is still no clear answer to the question, which affects the age, shape and size of the universe, and there is no consensus about its limbs.Because if the universe is finite, it should either be compressed or expanded.In the event that it is endless, many assumptions are meaningless.
Even in 1744 the astronomer JFCheseaux first doubted that the universe is infinite, because if the number of stars has no borders, why not shining sky and why is it dark?In 1823, G. Olbes argued the existence of boundaries of the universe so that the light coming to Earth from distant stars should become weaker due to the absorption of a substance that is in their path.But in this case itself, this substance must be heated to glow and no worse than any star.This assumption was confirmed by modern science, which claims that the vacuum is "nothing", but at the same time it has a real physical properties.Of course, the vacuum absorption of the photon energy leads to an increase in its temperature, resulting in the fact that the vacuum becomes a secondary radiation source.Therefore, if the actual size of the universe is infinite, the light of the stars that have reached the limit of distance, have such a strong red shift that begins to merge with the background (secondary) radiation vacuum.
At the same time, we can say that the size of the universe observed by mankind, of course, as finite speed of light itself.Distance 24 is the boundary Gigaparseksa cosmic light horizon.However, due to the fact that the expansion rate increases, the end of the universe is located 93 billions of light years.
most important result of cosmology was the fact that the universe's expansion.It was obtained by observations of the red shift, and then to quantify, in accordance with the law of Hubble.This led scientists to conclude that the Big Bang theory finds its confirmation.According to NASA, which were obtained by WMAP, the age of the universe, from the Big Bang, 13.7 billion years equals.However, this result is only possible if it is assumed that the model which is the basis of the analysis is correct.The use of other methods of valuation are obtained completely different data.
Touching upon the structure of the universe, it can not be said about its form.So far not found that the three-dimensional shape that would best represent its image.This complexity stems from the fact that so far it is not known whether the universe is flat.The second aspect is related to the fact that it is for certain is known about its multiple connections.Accordingly, if the size of the universe is limited space, you can move in a straight line in any direction you can be in the starting point.
As we can see, technological progress has not reached the level to accurately respond to questions relating to age, equipment and dimensions of the universe.Until now, many theories in cosmology have not been confirmed, but not refuted.
