Dark matter theoretically represents 85 percent of the total mass of the universe. However, it has not yet been proven in practice.
Only the DAMA/LIBRA experiment claims to have discovered dark matter, but this result is controversial. A new experiment, COSINUS, aims to confirm the existence of dark matter. It is located in the Laboratori Nazionali del Gran Sasso, the largest underground laboratory in the world. It aims to clarify whether DAMA-LIBRA actually detected dark matter and to achieve significantly higher accuracy than other experiments have done so far. The theory behind the experiment: If dark matter exists, then it must have a strong gravitational pull on the universe's planets. The results of the experiment will be published in The Astrophysical Journal.
