Scientists at University of Southampton have developed a 5D optical data storage crystal, sometimes called an “eternity crystal.” Using femtosecond lasers, data is written into nanostructures within quartz glass, allowing information to be stored in five dimensions. The crystal can theoretically store up to 360 terabytes of data and withstand extreme temperatures, radiation, and time—remaining readable for billions of years under stable conditions.

Scientists at the University of Southampton have developed a 5D optical data storage glass disc capable of storing up to 360 terabytes of data while remaining stable for billions of years. Data is written using ultrafast lasers that create nanoscale structures inside quartz glass. The disc is resistant to heat, radiation, pressure, and electromagnetic interference—making it ideal for preserving humanity’s most important records, from scientific data to cultural archives.
