Matter and subatomic particles

It was in the cosmic dark ages that matter appeared. To get closer to the birth of the universe, we are forced to look at the other side of time and space, at the side of the infinitely small. Between 0 and 380,000 years ago, the universe is so dense that light cannot escape. It is in the Large Hadron Collider (CERN) that scientists want to see what nature is hiding from us.
