O’Neill cylinder

O’Neill was inspired by the papers written by his students. He began to work out the details of a program to build self-supporting space habitats in free space.Among the details was how to provide the inhabitants of a space colony with an Earth-like environment. His students had designed giant pressurized structures, spun up to approximate Earth gravity by centrifugal force . With the population of the colony living on the inner surface of a sphere or cylinder, these structures resembled “inside-out planets”. He found that pairing counter-rotating cylinders would eliminate the need to spin them using rockets.This configuration has since been known as the O’Neill cylinder.

Internal view of the O’Neill cylinder
“One of my earliest Space Colony paintings was based on the giant ‘Model 3’ cylindrical habitats envisioned by Gerard O’Neill. I imagined the clouds forming at an ‘altitude‘ around the rotation axis. At this time the scene is bathed in the ruddy light of all the sunrises and sunsets on Earth at that moment as the colony briefly enters the Earths shadow, out at the L5 Lagrangian point where stable locations are easily maintained. Oil on canvas panel disposition unknown. “

In 1994, Egyptologist and linguist Daniel Jackson, Ph.D., is invited by Catherine Langford to translate Egyptian hieroglyphs on cover stones, also known as casing stones, that her father had unearthed in Giza, Egypt, in 1928. Jackson is taken to a U.S. Air Force installation and told by its commander, Special Operations Colonel Jack O’Neil, that the project is classified information. Jackson determines that the hieroglyphs refer to a “stargate” which uses constellations as spatial coordinates. On this revelation, Jackson is shown that the base has this Stargate, also discovered by Langford’s father. They use Jackson’s coordinates to align the Stargate’s metal ring with markings along its outside, and once all seven are locked in, a wormhole opens, connecting the Stargate with a distant planet. Jackson joins O’Neil and his team, consisting of Reilly, Porro, Freeman, Brown, Ferretti, and Kawalsky, as they pass through the wormhole.
