In zero gravity or microgravity environments, a gyroscope behaves differently than on Earth. On Earth, gravity provides a reference for the gyroscope to maintain stability, but in space, where there's no constant gravitational pull, gyroscopes rely on other principles. In microgravity, a gyroscope can still maintain its angular momentum. It will continue to spin and resist changes in its orientation, demonstrating the conservation of angular momentum. However, without a consistent gravitational

Gunpowder was first invented in China and began as a simple experiment with fire and minerals. Between the 900s and 1000s, it was used in warfare through fire arrows and explosive bombs. By the 1100s, this same invention powered fire lances—early guns—and rockets against invading forces like the Jurchens. This single discovery completely transformed the way wars were fought. Through trade routes and the Mongol expansions, gunpowder technology spread beyond China, eventually reaching Europe and r
