When Martin Kunze was 13, he wrote his name, number and address on a piece of paper and put it in a bottle, which he buried in the sand on a beach in the Mediterranean. He thought a beautiful girl would find it the next year and call him.

No one called for over three decades.

But then, three years ago, a dog-walking retiree found the note, had it translated and called Kunze’s  parents to say he’d found the bottle. Kunze, who is now 50, was amazed that someone took the time and effort to call. He believed that the person reached out because he was was looking for some “communication through time, some kind of contact,” according to GQ. 

Six years ago, Kunze began a project he calls the Memory of Mankind, which is basically an enormous time capsule meant to survive for thousands of years. The first tablet in the capsule, which is within a massive salt mine, addresses creatures a million years from now—whoever or whatever they may be—explaining that here lies “a preservation project” meant to protect knowledge about “our present civilization from oblivion and collective amnesia,” writes GQ.
