"The combination of a worldwide shift to GM crops and rising global temperatures led to a series of global disasters, destroying many natural resources and causing a permanent environmental imbalance. Earth’s leaders make the choice to outsource all food production to off-world corporately owned farm planets, known as ‘flatlands’." — Luke Sanger on the album Onyx Pyramid
The music, Sanger writes, is a kind of fictional soundtrack for a landscape of offworld megafarms, where a human skeleton crew has been reporting “auditory hallucinations” amplified by the effects of an artificial atmosphere. Audio scifi.
Several Low-Earth-Orbit (LEO) networks were proposed, but only one got off the ground: the Iridium system. The original Iridium proposal called for a "constellation" of 77 satellites, which gave the plan its name: the element iridium has atomic number 77, meaning that an iridium atom has 77 orbiting electrons. Before the satellites were launched, the constellation was scaled back to 66 active satellites, but no one wanted to change the name to Dysprosium.
I'd like to call the more general phenomenon that this is a specific instance of "ghost knowledge": It is knowledge that is present somewhere in the epistemic community, and is perhaps readily accessible to some central member of that community, but it is not really written down anywhere and it's not clear how to access it. Roughly what makes something ghost knowledge is two things:
It is readily discoverable if you have trusted access to expert members of the community.
It is almost completely inaccessible if you are not.
In this sense, most knowledge is ghost, particularly if you take an expansive view of what counts as an epistemic community.
