Now for the answer to question you probably weren't asking today: How does zero gravity affect the flight of a boomerang?
The Japanese Space Agency, JAXA, released this video showing that that answer is "not much." As Universe Today pointed out, while microgravity had little effect on the "roomerang," it isn't the same as space, which has zero gravity and is a hard vacuum besides. Aerodynamics are useless there. JAXA on the same mission released a fleet of paper airplanes to see how that they might fare during a descent through Earth's atmosphere.
