Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques.
After many years of preparations, CERN has approved a new experiment: the Search for Hidden Particles (SHiP). Physicist Alexey Boyarsky was involved from the start. "We know there is physics that's missing and we aim to find ...
