Zero gravity

Origin

Long before rockets pierced the heavens, scientists pondered the theoretical state of "zero gravity," a realm where the familiar pull of Earth vanished. But it wasn't until the mid-20th century, with the pioneering leaps of space exploration, that the phrase soared into public consciousness. As Sputnik orbited and Yuri Gagarin became the first human to experience genuine weightlessness, the world watched in awe. These early space voyages, where astronauts floated freely inside their capsules, transformed "zero gravity" from a scientific abstraction into a tangible, awe-inspiring reality, forever linking the term to humanity's audacious journey beyond its home planet.
