Storing data for large periods of time are becoming a big worry for todays companies, these days, with advancing technology makes this task specially harder. So what are our options, if we need to store data for thousands or even millions of years?
It is hard to communicate with future generations for a number of reasons:
1. It is very tricky to find a medium that could stay intact and not become damaged for so long.
2. Aside from the latter, it is also hard to predict what language future civilizations will be using, thus, we cannot put information in a specific language if it could potentially become extinct.
Recently, ANDRA which is a French nuclear waste agency, created a disk made out of only industrial metal Sapphire that could potentially last up to 2 million years, because of its high degree of resistance to scratches and damage. One of these disks is worth around 38,000 USD because of the high sapphire content. This amount of sapphire could go on to store over 40,000 amounts of miniature pages of text so that they can be viewed by future archaeologists through a simple microscope. The sapphire disk is just one of the few ideas currently being explored by ANDRA in an attempt to bring together and unite material scientists, anthropologists and archaeologists all around the world.
