What happened in the early moments of the Big Bang in the universe has been repeated at the CERN research center in Geneva. Therefore, in the history of the Universe they have receded more than anyone, until the first microseconds of the Big Bang.
If the cosmos really started with the Big Bang, we know that in the first microseconds exploited the Universe was a soup of basic elements, quark and gluons. All of them functioned at an energy density 20 times higher than that in the nucleus of the atom. In other words, the Universe was totally dense and incomparable in the first moments of birth, and it does not resemble what physicists had seen so far in nature or in particle accelerators. More than 350 physicists from all over the world have been able to see the matter in the CERN laboratories in Geneva, unlike what happened so far.
Since 1986, international scientific teams have worked on the formation of a quark/gluon plasma, announced by the theory (but never detected so far). In fact, quarkas remain "glued" to each other by gluons, that is, particles without mass or load and transporters of violent interaction of quarks. However, quarks are found within larger particles (protons or neutrons). Quark and gluon plasma, therefore, lasted very little time (only in a few microseconds) and was the predecessor of nuclear matter.
In order to obtain this original soup, a high energy ray of accelerated lead atoms (33 teraelectronvolts) has been needed. This beam collides in seven detectors. By colliding with very high energy heavy cores, there have been 100,000 times the temperature of the center of the Sun, freeing itself from it in an enormous energy density. In this situation, the forces that finally keep the quarkas within more complex particles have been overcome. After overcoming the barrier, quarks and their companions have been able to float freely for a time (only 10-24 seconds). Then, as the medium has cooled, they return to the inside of the matter.
With the creation of this original soup of gluon and quark there has been a new unknown dimension of matter. The new particle accelerator of the National Laboratory of Broohkaven, which will open in Long Island, New York, or the new hadron accelerator to be released at the CERN in 2005, will try to decipher this unknown territory.
