Hydrogen is the most common element in the universe. It determines the properties of stars and planets and is crucial for life on Earth—not least because of its role in climate-neutral energy supply. Generations of scientists in physics and chemistry have researched hydrogen very intensively, both in experiments and with the help of computer simulations. Despite its very simple structure—a hydrogen atom consists of only one electron and one proton—many properties have still not been conclusively clarified.
