Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [1] or, incorrectly, zero gravity. Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.
The Reduced Gravity Walking Simulator, or Lunar Landing Walking Simulator, was a facility developed by NASA in the early 1960s to study human locomotion under simulated lunar gravity conditions. Located at NASA's Langley Research Center in Virginia, it was designed to prepare astronauts for the Moon landing during the Apollo program .
Reduced-gravity aircraft training avoids neutral-buoyancy training's drag problem (trainees are surrounded by air rather than water), but instead faces a severe time limitation: periods of sustained weightlessness are limited to around 25 seconds, interspersed with periods of acceleration of around 2 g as the aircraft pulls out of its dive and ...
Portable, lightweight and durable, these dreamy loungers will change your chill-out game for good.
The reverse Trendelenburg position, similarly, places the body supine on an incline but with the head now being elevated. The Trendelenburg position is used in surgery, especially of the abdomen and genitourinary system. It allows better access to the pelvic organs as gravity pulls the intra-abdominal organs away from the pelvis.
This take on the woman-on-top position offers the same benefits and control as the regular cowgirl position. To perform the reverse cowgirl, you’ll set up the same way, but instead of sitting ...

Surface tension dominance: Without the overwhelming force of gravity, surface tension becomes a dominant force in fluid behavior, significantly affecting liquid spreading and containment. [11] Particle suspension: In low-gravity environments, particles in fluids remain suspended for extended periods, as sedimentation and buoyancy effects are ...
