About Space
According to nayvyznanishoyu today cosmological model, the universe arose as a result of the so-called Big Bang. Before the Big Bang there was no space and time. Only after the Big Bang the universe began to expand, creating the space and time in the four-dimension, which is called "space - time". Since from a scientific point of view it makes no sense to ask the question that came to the universe in the same sense no need to ask what was beyond, because "limits" existed. ultravent The universe is expanding is not in space, it expands with space. The period conventionally called the Big Bang time from "zero" to several hundred seconds. Modern scientific knowledge does not allow to penetrate the moment began the Big Bang, and catch that split second, which was to "zero". The known laws of physics can not explain what happened in the period between the start of the Big Bang and instantly through 10-43 seconds after the start (this incredibly small fraction of a second, a fraction of the unit displayed in the numerator ultravent and unit with 43 zeros in the denominator, call time Planck) are, however, not able to create and theory of the beginning of the Big Bang. At the moment 10-43 seconds the universe was infinitely small, hot and dense. The next negligibly small fraction of a second it has changed - expanded from infinitesimal size to the size of a grapefruit release of energy and elementary particles - quarks and antiquarks.
By the time when the universe lived ten thousand of a second, formed of quarks, protons and neutrons. After a second after the beginning of the Big Bang the temperature dropped to 10 billion degrees; in a universe dominated by radiation and light particles such as electrons and their antiparticles (positrons). A little more than a minute after the start of the Big Bang, protons and neutrons began to connect with each other, forming a helium nucleus consisting of two protons and two neutrons. Most of the helium nuclei that exist to this day in the universe formed in the first quarter of an hour after the start of the Big Bang. And only 300-500 thousand years when the universe rozshyryvshys, cooled to a temperature of 3000 degrees Kelvin, electrons were connected ultravent with the nuclei of hydrogen ultravent and helium atoms forming the first, there was a "thinning" the cloud space and the universe first became transparent to light.
In 2003, using a running NASA (US National Aeronautics Department and Space) space probe, equipped with special equipment, we measured the temperature of the microwave background (relic) radiation to within a millionth of a degree. The results of these measurements revealed that the universe is 13.7 billion years old and that the formation of the first generation of stars began 200 million years after the Big Bang.
Studying clusters and super-clusters of galaxies to create a model of the universe on a large scale, that determine how matter is distributed in a very large space. In this sense, the most significant result obtained cosmology in the last 50 years is that the universe seems to consist of large hollow bubbles that intersect with one another, as a result they resemble a sponge. In this context, clusters and super-clusters of galaxies are distributed ultravent along the walls of bubbles forming fibrous ultravent structure length of tens of millions of light years. These bubbles are cavities that contain dark matter. Studying the dynamics of motion of galaxies (their mutual removal caused by the expansion of the universe) showed that the direction of the constellation Sagittarius, perhaps there is a huge concentration of matter, the so-called big point of attraction that their gravity attracts even the local super-clusters of galaxies.
The most common in the universe is the lightest elements - hydrogen and helium. Sun, stars, ultravent interstellar gas in the number of atoms up to 99 percent of them. The share of all others, including the most complex "heavy" elements account for less than 1 percent. 76.5 percent by weight hydrogen accounts for 21.5 per cent - into helium, 0.3 percent - in neon, 0.82 percent - in the oxygen, 0.34 percent - carbon, 0.12 percent - in nitrogen, 0.12 percent - in iron, 0.07 percent ultravent - on silicon, 0.06 percent - magnesium, 0.04 percent - for sulfur. Balance - 0.13 percent ultravent - accounts for all other elements. Thus, the most common chemical element in the universe is hydrogen. Invisible to the naked eye, this gas can be detected by radio telescopes ultravent radio waves released by the length of 21 centimeters. Hydrogen filling almost the entire interstellar space, but it is incredibly sparse: just one atom at 10 or even 100 cubic centimeters. However, since the vast interstellar space, large and total gas. Some hydrogen clouds "hot", they have a temperature of 7,500 degrees, in rare cases, the hydrogen temperature reaches ultravent millions of degrees. There are so
