Memory of Mankind

Several motivations underlie the project. The primary ambition of MOM is to preserve an image of our era, created by numerous participants all over the planet. MOM will also contain information which our society is obliged to forward to the future, e.g. descriptions of nuclear waste repositories. MOM collaborates with the NEA and SKB. Although the most obvious ambition and often described in the media is the concern about preserving our knowledge, this is not the primary goal of MOM. Serving as a time capsule MOM is both: in a time frame of millennia it is the story about us, and in a time frame of decades it is a backup. In times where global warming, nuclear danger and biological warfare threaten the existence of civilization, saving the core knowledge and culture acquired over centuries is a backup measure.[2] In case of a collapse, the MOM project could help survivors to rebuild civilization. Linked to this, another reason is of political order: facing the lack of reactivity of authorities concerning global warming, the MOM project is a reminder of what can happen. Roman and Greek civilizations whose histories have been reconstructed by the small percentage of texts and artifacts which survived until our days are examples that have inspired the MOM project. Finally, it's a critique of our digital civilization—according to Kunze, maybe nothing of the 21st century will last in the future, since most of our interactions are now virtual. The "accuracy versus bullshit" is one of the main themes of the MOM project, worried about loss of information, the project can only aim to save a fragment of the information produced until today, but this fragment has to be representative.[3]

MOM's containers in the salt mine

Collecting content is inevitably subject to bias. In order to take this into account, the content is split into three sections and as much meta information as necessary is added to any contribution in order to enable future finders to apply source criticism. The collecting process is not centralized, subject to every country/region/entity.

The three sections are:

• Individual content: content uploaded by individuals, accompanied with a declaration of why this particular text is worthy of preservation. Each individual content is marked as "private content" in the overall MOM index;
• General content: content collected automatically to avoid bias. e.g. collecting the daily editorials of newspapers worldwide, randomly selected Facebook profiles, weekly/monthly magazines of different topics (with the "meta information": numbers of readers; reason for selection of the respective magazine; description of the target group). The language-deciphering tool ("pictionary”) is also part of this section;
• Specific content: in this section MOM is used as a "medium". Outside institutions bring content to MOM and use the storage and the medium (ceramic microfilm). e.g.: nuclear industry (information about waste repositories). Universities use MOM for awards.[4]

The Hallstatt salt mine is the oldest salt mine continuously exploited by humans. Several factors contribute to its suitability for the MOM archives. As well as the depth and relative stability of the mine, the salt absorbs moisture and desiccates the air, and has a natural plasticity that helps to seal cracks and fractures keeping the caverns watertight.[5]

Ceramic tablets in their containers

Sumerian clay tablets greatly inspired MOM's tablets. These modern variants are made of a ceramic material that is capable of preserving the information that they contain, as they are less vulnerable to corrosion, biological degradation, and ordinary weathering and wear for a longer time than other materials which have been used to record information- it resists up to 1200 °C (2200 °F), chemicals, water, radiation, magnetism and pressure and can "only be destroyed by a hammer" (even if a tablet breaks, information will not disappear). The goal is to have the most durable support available, able to carry the message over a long span of time (one million years). The tablets measure 20x20 cm, one type carries images and text with a 300 dpi resolution, the other type is "ceramic microfilm" and carries up to 5 Million characters. It is a requirement that the information be analogue and recognizable as data to future finders.

Variations of languages over time and even the hypothesis of an alien intelligence discovering the MOM archives has been anticipated. Again, the creators of MOM take inspiration from historical methods. They designed their own "Rosetta Stone", translated in several languages with the appropriate character set and number system, an astronomical time indicating “2013” (via extremely rare events of simultaneous transits of Mercury and Venus) and thousands of images depicting concrete situations with the corresponding words, completed by the theoretical volumes of the main languages, e.g. phrases, grammar, thesaurus, orthography.[6]

Obverse (left) and reverse (right) of the token given to the participants of the MOM project

A token (a disc 6,5 cm in diameter) will be given to all participants of the MOM project. On its limited surface the token indicates a spot on our planet with a precision of some ten meters. The front-side depicts the outline of Europe, pointing to Hallstatt. The backside shows the position of the entrance to the MOM relative to the shape of the Hallstatt Lake. In addition there is a hint to the salt mineral (a cubic structure). Due to the design of MOM and the token the archive can only be retrieved by a society with a similar technical and physical understanding of the world as we have had since the late 1980s. This is intended to ensure that techniques to decode the content are available to future finders. An "Ariadne's thread" in the form of ceramic tablets with mathematical indications of the direction and depth will be placed in the entrance tunnel, including "gaps", which are also mathematically indicated, in order to avoid accidental recovery by an immature society. An instruction for a ceremonial and passing rite is attached to this token: the owners are supposed to gather every 50 years to commemorate and decide whether Humanity still knows the content of MOM and if extensions are needed. The token should be transmitted to the descendants of the owners.[7] Unlike other time capsules which predefine opening dates (not considering if at that point an appropriate addressee will exist), MOM's token defines the culture rather than the date of the opening by ensuring a pre-mature society would be unable to interpret the token.

Memory of Mankind distinguishes itself by asking for contributions from both public and private entities, be they companies or common people). Contributions can be financial or simply content to be stored. Cooking recipes and personal stories are examples of contributions that may be stored. In exchange for a contribution the contributor receives one of the ceramic tokens.

MOM is a global project: in order to enable citizens of every country to represent themselves the costs for tablets vary based on the gross national income per capita ranking table of the World Bank.[8]
