Zero Gravity

Zero gravity, often referred to as microgravity, occurs when objects in space experience free fall, creating the sensation of weightlessness. In this state, both astronauts and their spacecraft fall toward Earth at the same rate, resulting in an absence of gravitational effects on their bodies. This environment allows for unique scientific experiments and observations, as the behavior of fluids, flames, and biological systems differ from those on Earth. It's important to note that gravity still exists in space; it's just that everything is falling together, which creates the feeling of floating or being in "zero gravity."
