Sapphire Memory Disk: Everlasting

sapphire memory
Why does anybody need an everlasting memory disk? To communicate with the future civilizations. The long-term, lasting approximately over million years, solution is offered to be made of two thin disks of industrial grade gemstone sapphire, about eight inches across. A single disk is estimated to store 40,000 pages of pictures and/or text, before the disks are molecularly fused together. The prototype disks costing an estimated $30 thousand will be submerged in acid to simulate ageing and test durability. How did this come to life? A French nuclear waste management company ANDRA created the Euroscience Open Forum to gather experts and interested parties from a variety of fields talk about what we might do to ensure the communication of important information to the future. That’s one of the first answers.
