A Scientist Created Wigner Crystals to Simulate Dead Stars on Earth

via MOTHERBOARD

“Gravity crystals” aren’t just consumable items in Fortnite anymore. A scientist has figured out how to use cheap household materials to create gravity crystals to study the exotic interiors of distant dead stars right here on Earth.

To create a Wigner crystal, electrons must be confined to a space that forces them to remain close together even though they naturally repel each other. These conditions are met in white dwarf stars, which are the remnants of stars that have exploded in supernova and collapsed into super-dense spheres about the size of Earth.
