The Search for Dark Matter

The video explores the search for dark matter, an invisible substance believed to make up 85% of the universe's mass. Scientists work in deep mines across Europe and America to detect these elusive particles, which rarely interact with other matter. The video details the use of liquid xenon detectors shielded by lead to capture scintillation, a flash of light indicating a particle interaction. Despite challenges, the discovery of dark matter would be a monumental breakthrough in understanding the universe's structure and the forces holding galaxies together.
