“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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
