Watch live the lecture of the well-known physicist and popularizer, prof. Peter Kulhánek! A story about the relationship between cosmology and the physics of elementary particles, about how accelerators make the Little Bang and prepare the primordial matter from which the universe was formed 14 billion years ago. The quark-gluon plasma was first prepared at CERN in 2000, and research into the properties of this germ soup is one of the greatest adventures in contemporary science. At CERN, you can observe how the first neutrons and protons were created, as well as how the four forces of nature appeared in the universe.
