Humanity's most precious data is stored in a vault buried in a mountain in the cold, desolate, Norwegian archipelago of Svalbard.
The so-called Global Seed Vault contains millions of seed samples from nearly every country on the planet. Its mission is to store the seeds as a preventative measure against a possible global catastrophe such as a nuclear war or asteroid impact.
One of the great secrets revealed is that the vault has recently received a new neighbor - the Arctic World Archive. It contains not seeds but some of human history's most important books and documents. This leads to concerns that our world has slowly but surely begun the march toward its own destruction.
A Norwegian technology company is responsible for constructing the vault and the technology they've used guarantees that the information stored within will survive for at least 1000 years.
The Arctic World Archive contains government and research organization documents from around the world. The unique thing is that private companies and even private individuals can pay to have their information stored there until the next millennium at least.
The tech vault keepers store the data not in digital format but in analog. In other words, the data is stored on photosensitive film which they say is a much more secure alternative to anything digital.
