Fifth Dimensional Memory and the Fortress of Solitude

In the quest to store information permanently, the University of Southampton has developed a memory chip so durable that it will last until after our sun burns out:
Using nanostructured glass, scientists from the University’s Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing. ...

Coined as the ‘Superman memory crystal’, as the glass memory has been compared to the “memory crystals” used in the Superman films, the data is recorded via self-assembled nanostructures created in fused quartz. The information encoding is realised in five dimensions: the size and orientation in addition to the three dimensional position of these nanostructures.

Professor Peter Kazansky, from the ORC, says: “It is thrilling to think that we have created the technology to preserve documents and information and store it in space for future generations. This technology can secure the last evidence of our civilisation: all we’ve learnt will not be forgotten.”

The researchers will present their research at the photonics industry's renowned SPIE Photonics West—The International Society for Optical Engineering Conference in San Francisco, USA this week. The invited paper, ‘5D Data Storage by Ultrafast Laser Writing in Glass’ will be presented on Wednesday 17 February [2016]. The team are now looking for industry partners to further develop and commercialise this ground-breaking new technology. Contact Professor Peter Kazansky to find out more.

In a related report from 17 February 2016, Engadget revealed Southampton's curious mixed impulse toward the ultra-new and ever-permanent:
Researchers at the University of Southampton's Optical Research Center announced on Tuesday that they've perfected a technique that can record data in 5 dimensions and keep it safe for billions of years. The method etches data into a thermally stable disc using femtosecond laser bursts. The storage medium itself holds up to 360 TB per disc, can withstand temperatures up to 1000 degrees C and are estimated to last up to 13.8 billion years at room temperature without degrading.

Each file is comprised of three layers of nanoscale dots. The dots' side and orientations, as well as their position within the three standard dimensions, constitute its five dimensions. These dots change the polarization of light travelling through the disc which is read using a microscope and polarizer.

... In the three years since their first demonstration, they've ... recorded the entirety of the Universal Declaration of Human Rights (UDHR), Newton's Opticks, Magna Carta and Kings James Bible.

"It is thrilling to think that we have created the technology to preserve documents and information and store it in space for future generations," Professor Peter Kazansky from the ORC said in a statement. "This technology can secure the last evidence of our civilisation: all we've learnt will not be forgotten."
To make their research accessible to the public, scientists exploit popular culture and so must not complain when the masses comprehend science with pseudoscientific labels and mystical weirdness. Tagging this memory chip with fifth dimensional capabilities shows the University of Southampton's media-savvy, and they have asked us to respond with one big "quantum wow." Anything in '5D' is incredibly popular right now; it is a pseudoscientific catch phrase, like 2016's anti-ageing creams, which claim to work by altering your DNA. Invoking the fifth dimension in a press release alludes to a gnostic vault up to a supra-spiritual existence. 5D is a loosely-grasped point of perspective, above regular three-dimensional reality and the fourth dimension of spacetime. I have previously alluded to 5D concepts herehere, here and here.

Southampton's optics researchers do not show much interest in the deeper meaning of durable memory, of what it means to preserve knowledge until after our sun burns out. If they knew anything about the Superman story, they would understand that crystallized memory implies a push beyond the normal human capacity to remember, toward the alienated superhuman, into the moral and physical challenges of permanent isolation.
