From Fluid to Universe

    The universe was once a super hot fluid shortly after his birth, according to the first results of experiments reconstruct Big Bang conditions or the big bang.Scientists working at the world's biggest particle that is the Large Hadron Collider at CERN near Geneva, Switzerland found that exotic soup temperature over 10 degrees
Celsius trillion created shortly after the birth of the universe.



Hot and sticky material known as quark-gluon plasma is like a hot liquid, according to the results of their findings.It provides the perfect environment for the first particles and atoms to form which then generates the stars and galaxies around us today. Similarly, as quoted from the Telegraph (20.11.10).The findings were surprising to physicists because of these findings refute the accepted view of what happened immediately after the creation of the universe is that the Big Bang that spew superheated gas that clump together to form matter."In the first events of the universe, the material is actually like a very dense liquid," explained Dr. David Evans, who is a particle physicist at the University of Birmingham which is the lead investigator in the experiment."These findings tell us about the early evolution of the universe will inevitably have implications for the present form."We must do more analysis and give more thought to understand this, but these results are truly amazing."The results are the first results issued by a multinational group of more than 1,000 researchers working in the experiments with the Large Hadron Collider that began two weeks ago.They used a particle accelerator to smash atoms together lead a known as the ALICE detector to create a "mini big bang" that are thought to mimic the conditions that exist within fractions of a second after the universe was created.Balls are very small fire that is created in the 27.3 mile long particle accelerator is buried deep as 5.2 km below the hills of Alpine foothills around the border of Switzerland and France, reaching more than 10 trillion degrees centigrade for seperseikian seconds.At this temperature the atoms and particles that build it melted into the basic constituent parts known as quarks and gluons.In general, physicists believe that the high temperatures generated after the Big Bang, the energy that normally binds quarks and gluons together to weaken significantly the yield of material that is similar to the gas.Previous research five years ago at the Relativistic Heavy Ion Collider in Upton, New York has created a four trillion-degree temperatures and showed that the temperature of the quark-gluon plasma is similar to the fluid, but many suspect that when the temperature increases, the plasma will be similar to gas.However, recent findings indicate that CERN is not the real thing and the results are expected to change the conventional thinking in physics when scientists try to figure out why the quark-gluon plasma is not as predictable.Dr. Evans said: "These theories suggest that the energy that holds quarks began to weaken at a temperature just after the Big Bang and the quarks would move freely like a gas."We found that the strong energy that holds quarks still keeping most of its strength even at high temperatures. Quarks still interact with each other beyond our expectations."These results will help us understand more about the mysterious period before the protons and neutrons formed in the early universe."Professor Brian Cox is a particle physicist at the University of Manchester and presenter of the series Wonders of the Universe BBC which will soon be broadcast to say that the discovery opens up many questions about the way the early universe.He said: "They use different metaphors to explain how apparently because of its shape will not be like any liquid that we used to know.""They talked about the strength of the interaction between quarks and how these particles behave together. These particles should interact more strongly than expected and therefore it is like a liquid."These experiments provide new energy to our rules and therefore saw the unexpected nature of a lot of fun. Discovery is very exciting."
