5D Crystals Can Store Data Virtually Forever, Scientists Say

Researchers at the University of Southampton have recently announced that they are able to store and retrieve huge amounts of five dimensional data on quartz crystals.
The technology has immediately received a cool nickname: the "Superman memory crystal" - after the "memory crystals" used as storing devices in the Superman films.
I. How does it work?
“…the data is recorded via self-assembled nanostructures created in fused quartz, which is able to store vast quantities of data for over a million years,” explains a press release. “The information encoding is realized in five dimensions: the size and orientation in addition to the three dimensional position of these nanostructures.” [1]
That sounds complicated, but what it basically means is that, using ultra-fast lasers, we can now encode a piece of quartz with 5D information in the form of nanostructured dots separated by only one millionth of a meter.
The storage allows unprecedented parameters including 360 TB/disc data capacity, thermal stability up to 1000°C and practically unlimited lifetime.
The Mysterious Ancient Crystal Skulls of Mesoamerica

These mysterious crystal skulls reunite all the needed features (solid, beautiful, numerous and awe inspiring) for them to survive long enough for their possible message to be decoded by an advanced species.
"Recent electron microscope analyses of skulls by the British Museum and the Smithsonian Institution revealed markings that could only have been made with modern carving implements." 
Interesting times await us just around the corner, so - who knows?! - maybe one day, soon, I will be able to report to you that an ancient crystal skull has been discovered to contain the real history of our planet and its inhabitants.
