Classification

• Space Station: any inhabited or manned immobile artificially constructed facility
• Space Structure (aka Space Infrastructure): any artificially constructed unmanned structure used to support other activities, defend a place, or aid navigation

Slingshots

A metallic "T"-shaped structure (viewed from above) built by an ancient, unknown race. The horizontal top ranges from a few hundred feet up to ~1,000 feet long and 40–100 feet wide; the vertical leg runs 800–3,000 feet long and 80–300 feet wide.

Ships entering the vicinity of the horizontal leg are "grabbed" by an energy beam that maneuvers them to the T's crosspoint, where a brief spherical energy field surrounds them (a few seconds to about a minute) before flinging them along the vertical leg at 3 to 50 times the ship's maximum rated speed, with no reported damage. Each Slingshot flings a ship to a specific, often distant location (hundreds of millions of miles away) — sometimes another Slingshot. Patterns of up to 5 linked Slingshots have been found. Hundreds of Slingshots have been discovered in known space; "interim" Slingshots (destinations for another Slingshot) aren't always observable in normal space, sometimes shimmering in and out of existence. Ships using a Slingshot sometimes appear as pulses of light while traveling.

Stargates

Also built by an ancient, unknown race — but a different one from the Slingshots' builders. Differences in appearance, purpose, and engineering suggest no connection between the two builder races.

Oyster Shells

Metallic, hollow containers built by yet another ancient, unknown race, roughly 2–5 meters long, 0.9–2 meters high (most 0.9–1.1 meters), 2–4 meters wide, with a shell about 4 centimeters thick. Some have been blasted open by asteroid impacts or weapons fire; others appear to have opened spontaneously; some are found only as scattered debris; others have clearly been opened by someone else already.

Contents vary: sometimes nothing; sometimes a small cube (~1 inch per side) or larger cubes (up to 4.4 inches per side); sometimes many cubes; electronic devices (some still active); electromechanical devices. Many shells bear interior writing that has never been successfully translated, despite many attempts. The function of the cubes and devices remains entirely unknown.

Open Questions

• No confirmed connection has been established between the Slingshot, Stargate, or Oyster Shell builder races — whether they are 1, 2, or 3 distinct unknown civilizations is not resolved
• The Oyster Shells' writing, cubes, and devices remain entirely unexplained — deliberately left as an open mystery
