As a result, the scientific method was abandoned and their technological development ground to a halt. However, gravity technology by itself had no application other than transportation, and was such a bizarre discovery that their scientific theorems couldn't accommodate it. This enabled them to engage in of wars of conquest not only on a planetary but a galactic scale. The Roxolani's method of manipulating gravity is absurdly simple, and they were thus able to begin utilizing aircraft, spacecraft, and even faster than light travel during their Age of Sail. When they are interrogated, the truth becomes evident. The battle is short, and most of the invaders are killed. Humans retaliate with automatic weapons and missiles. But as they begin their assault, things take a turn for the absurd - the Roxolani attack with flintlock weapons and black powder explosives. Humanity is awed by the invaders, as the maneuverability granted by that technology suggests the rest of their civilization is equally impressive. The Roxolani anticipate a simple and rewarding campaign, as they can detect no use of gravity manipulation, the cornerstone of their civilization.

During a routine journey of conquest, they happen upon Earth. The story is told through limited third person point of view, with most of the story concerning a single Roxolani captain. The Road Not Taken is a short story by Harry Turtledove, set in 2039, in which he presents a fictitious account of a first encounter between humanity and an alien race, the Roxolani.
