It is the cosmic dark age that the matter appeared. Before Big Bang there 13.7 billion years there was nothing, space did not exist, the time either, it was nothingness. The WMAP telescope showed us a picture of the Universe, just 380,000 years after the Big Bang, but we're still not able to attend her birth.
Between 0 and 380 000 years, the universe is so dense that light can not escape. This period will always remain invisible. To get closer to the birth of the universe, we are forced to go across time and space on the side of the infinitely small. It is in the Large Hadron Collider (CERN) that scientists want to see what nature we seek.
This machine to reproduce the Big Bang, centralizes all hopes of particle physicists. In this machine, protons are accelerated to the speed of light and 800 million collisions per second are produced to analyze interactions. The LHC could lead to unexpected phenomena such as generating the dimensions of parallel worlds.
