In the magnificent plan "Memory Of Mankind" which preserves the memory of mankind in the rock of salt, personal memory can be preserved

The modern society and the world are also instantaneous in the history of the earth of tens of thousands to hundreds of millions of years, memories and records are lost one after another after the times have passed. In addition to the flow of the times, the project of preserving the "now" of human beings that can be lost even by natural disasters and wars, etc. for thousands of years by storing them deep inside hard rock salt "Memory Of Mankind"(MOM: memory of mankind) is being advanced.

Man Of Mankind is a scenic spot in central Austria,HallstattIn the old rock salt salt pit outside of the town, we have a modern memorySave in readable stateIt is a project to try. The mountain is adjacent to the town that is also registered as a UNESCO World Heritage Site, and tunnels for preservation using galleries dug from the hillside are made.

A tunnel leading to the tunnel for storage.


There is a space for storage at the end of the tunnel, and it is a mechanism to save tablets (boards) for storage made from clay (mud) by a special manufacturing method.


In the movie described about the MOM project, it is possible to see the aim and the inside of the tunnel a little.

MOM Memory of Mankind, greatest time capsule ever - YouTube


About 30 years after about 1000 years from now, how much memory of the society we are living now is left?


Although computers have developed technologies and various storage equipment has been developed, the storage period is considered to be around 50 years even if it is long from 5 years. In other words, it is difficult to reliably store information until 1000 years, regardless of which existing technology is present.


As time goes by, the shape of storage device will change. "I can not do anything when I combine a floppy disk that everybody used with a smartphone at once," Dr. Martin Stürzlinger who is involved in the MOM project.


Furthermore, storing the data is not "free". Even though I thought that "I am saving data to the cloud service so it's okay ..."


If contracts or services themselves are terminated somehow, that data may be lost.


Also, the way information is stored changes. In the past, photographs were common as they recorded the landscape of families.


However, since the beginning of the 21st century, many things are saved in the form of photograph "data", and many things are not left as shapes.


"Our time has benefited from information more than ever, but at the same time there is a possibility that it will be an era that leaves little information in posterity. In fact, in the first era of this 21st century, It may be "a dark 21st century" where little records are left behind, "said Lioba Theis, Professor of History and Culture at the University of Vienna.


For example, what will be the "ruins" that will be left as "records in the early 21st century" after 1000 years? It is probably "tomb" or ...


It may be characters written in the "monument" built in some places.


Or it may be a manufacturer's logo engraved on a ceramic pipe.


However, these alone do not preserve the "era" very much. For that reason, efforts like MOM (Memory Of Mankind) will become necessary.


In MOM, we save the tablet that recorded the information in the rock salt pit as mentioned at the beginning. The rock salt layer made of huge amount of salt is a very strong formation and it has a function to keep the humidity in the air properly, so it is suitable for preserving things. In addition, since the rock salt layer is covered with soil of mountains of hundreds of millions of tons, it seems that there are features that are not easily affected by changes in the environment.


A box stacked in a cabinet with rock salt. Inside of this, tablet carved information is kept.


This tablet is classified as "Level 1" and it is used to store general information. It is a special porcelain board with a size of 20 cm × 20 cm × 7 mm and can withstand the high temperature of 1,300 ° C.


It is possible to record information of 50,000 characters on one tablet as follows. Characters are actually carved on the surface of the board and everyone can read information visually. Unlike digital data etc. which require dedicated equipment, it is one of MOM's concepts that anyone can obtain information at anytime with a tablet.


Furthermore, it is possible to print not only letters but also photos. With print quality of 300 dpi, color printing with four colors is possible, and after printing it is protected against ruggedness with a transparent protective film.


In this way, it is possible to leave images and descriptive texts. However, it seems that you can not handle data such as music and movies.


Furthermore, the "Level 2" tablet for storing scientific documents is as thin as 20 cm × 20 cm × 1 mm, and the material is "Ceramic Microfilm" used. It is possible to store as many as 500,000 characters per sheet, and it seems that it is designed to store information in a readable state by enlarging it by 10 times.

"Memory Of Mankind physically backs up human memory," says Martin Kunze who launched the MOM project. "MOM is an effort to protect humankind's memories from the influence of magnetic force, electricity, heat and water, radiation, natural disasters, human destruction etc."


"MOM has our stories, memories, knowledge in salt rocks in the suburbs of Hallstatt ... ...."


"We are going to keep it for hundreds of thousands of years."


Andreas Murray, who is in charge of the Tourist Board near Lake Town in Hallstatt, says, "Customs and traditions are very important in our identity. To describe and preserve these are now It is one of the important puzzles to explain the era, MOM is a way to preserve the present era for future generations, "he says about the significance of MOM's efforts.


In addition, 50 "tokens" showing the location of MOM by map are made and distributed to people concerned scattered around the world certified by MOM. By doing this, even if the current civilization ceases, it is thought that future civilizers will be informed of the existence of MOM and old memories can be conveyed.


MOM is a project being advanced by academic institutions, newspaper companies, libraries, etc. Actually, people in general can save their own memories. The MOM website can purchase the right to store the tablet at 294 euros (about 34,000 yen), and the tablet design can be laid out freely by oneself. As the plan for yourself and the plan for presenting to someone is prepared, it seems to be used for the purpose of permanently preserving important memories of families, important pets, friends and so on.
