Current Events: Large Hadron Collider (LHC) generates a 'mini-Big Bang'

For several years now Scientists have been working on an enormous machine at the Franco-Swiss border this machine is the.. Large Hadron Collider. The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator, intended to collide opposing particle beams of either protons at an energy of 7 TeV (1.12 microjoules) per particle, or lead nuclei at an energy of 574 TeV (92.0 microjoules) per nucleus.
However during this current event I won't be talking about what the Hadron Collider is because last year i did that for current events, so during this current event I am going to be writing about an experiment that was recently done using the Hadron Collider.
The experiment ended up creating temperature's that were a MILLION times HOTTER than the CENTER OF THE SUN! So until now the worlds highest energy particle accelerator has be trying to collide protons and uncover the mystery of the universe formation which is what this whole experiment was about.
Scientists say that these collision might help spy the Higgs boson particle and and maybe some signs of some new physical laws. However over the next for weeks the LHC (Large Hadron Collider) is going to be concentrating on analysing the data from the lead collisions. By doing this they are hoping to learn more about the Plasma that the universe was made of a millionth of a second after the big bang (assuming that's how the world was created 13.7 billion years ago.)
To do all of this/ figure this out scientists have constructed several experiments with the LHC. One of these experiment is called ALICE. This particular experiment has been designed to smash lead ions together. One of the scientists working on ALICE David Evans (University of Birmingham, UK. Say that "The collision obtained were able to generate the highest temperates and densities ever recorded, produced in an experiment.
Because the temperatures created we a million times hotter than the center of the sun, and these temperature's even protons and neutrons (made up of the nuclei of atom) will melt which will result in a hot soups of dense quarks and gluon's (quark-gluon plasma. plasma is believed to have existed just after the Big Bang. After the LHC finishes colliding lead ions, it will go back to smashing together protons once again.
