MICROGRAVITY: Space Effects On Humans- S5E7 [4k Documentary]

Microgravity, also known as zero gravity or zero-G, is a condition in which objects appear to be weightless and float freely. It occurs when the gravitational forces acting on an object are in balance, resulting in the sensation of weightlessness. Microgravity can be found in a number of different environments, including in orbit around Earth or other celestial bodies, in free fall, and inside aircraft that fly parabolic trajectories. It is commonly experienced by astronauts during spaceflight, as they orbit Earth in a spacecraft that is in free fall around the planet. Microgravity has a number of unique effects on the human body and other objects. It can cause changes in fluid balance, bone density, and muscle mass, and can also affect the behavior of fluids and gases. Microgravity also has a number of scientific and engineering applications, including the study of materials science, fluid dynamics, and biological systems. #planets #universe #documentary #zerogravity
