Today, I learned that:
Scientists at the Optoelectronics Research Centre of the University of Southampton, on England’s Southern coast, have made a major step forward in the development of digital data storage that is capable of surviving for billions of years. Using nanostructured glass, they have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing.
The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1000 °C and virtually unlimited lifetime at room temperature (13,8 billion years at 190 °C ) opening a new era of eternal data archiving. This very stable and safe form of portable memory, could be highly used to store massive quantities of information, such as those found in national archives, museums and libraries.

Two examples of eternal 5D storage, King James Bible and the Universal Declaration of Human Rights. Copyright and photos by the University of Southampton 2016
In 2013, they demonstrated a 300 kbyte digital copy of a text file recorded in 5D, and now other documents such as the Universal Declaration of Human Rights (UDHR), Newton’s Opticks, Magna Carta and Kings James Bible, have also been saved.
Further information about this amazing storage technology can be found in reference # 1, below.
That’s what I learned in school !
