In collisions between nucleons or nuclei at high energy particles and their anti-particles, or matter and anti-matter, are copiously produced. We will discuss in this talk how the properties of the produced matter can be studied to shed light on the state of the universe a few microseconds after the big bang. Modern nuclear physics experiments have thus provided evidence for a phase transition in the early universe. We further demonstrate how the produced antimatter can be isolated and transformed into highly collimated particle beams. With such anti-matter beams new experiments can be performed. They include the production of anti-hydrogen, on which a series of fundamental measurements are underway.
