I read there suggestion to carve in stone, and on second view it don't look bad idea. But I suggest not just one stone, but build many hills on large piece of land and place them to form giant QR code, for example 1px=1m (resolution is not random, but it is typical for modern Earth imaging satellites, and for other Earth imaging technologies). I think, in 100 years, most probably, will exist technology to make photo (or drawing) from height and then translate it into bits and decode text. And to find it, I think will be enough to place in book geocoordinates and even most probably, Earth will be still round and even if GPS will not exist, somebody will know, how to convert GPS coordinates to what will exist. With some luck, possible that these giant pictures will notice few big information entities and place in their archives, so history will save them. Sure, here quality have not less importance than quantity, even so powerful entity as Life could disappear, so need to somehow attract attention of few, not only one. |
