The researchers of the university of Southampton have developed the process of laser writing in 5 dimensions on nanostructured glass.
An incomprehensible process for the common mortal but whose application makes us dizzy.
By registering a piece of information every millionth of billionth of a second, the English university can store 360 Terabytes of information.
And this, almost eternally (the disc resists for 13,8 billion years at 190°C).
In short, humanity fits into a pocket forever.
Somewhat humbling.
