  2. Weightlessness - Wikipedia

    en.wikipedia.org/wiki/Weightlessness

    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.

  3. Neutral buoyancy simulation as a training aid - Wikipedia

    en.wikipedia.org/wiki/Neutral_buoyancy...

    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 ...

    Zero Gravity "G-FORCE ONE" aircraft People in the reduced-gravity aircraft. As of August 2022, the price of a flight for a single passenger starts at US$8,200. [12] The unique Weightless Weddings Experience is also included in the list of services [13] Noah and Erin Fulmor were the first couple to get married in weightlessness. [14]

    Incredible Adventures is a Florida company established in 1995, offering private zero-gravity flight training in Tampa, Florida; About the NASA Reduced Gravity Research Program; Vegitel ltd is a Russian company that offers zero-gravity flights in an IL-76 MDK wide-body aircraft; Virtual tour of the Airbus A-300 Zero-G.

  6. Proper acceleration - Wikipedia

    en.wikipedia.org/wiki/Proper_acceleration

    This state is also known as "zero gravity" ("zero-g") or "free-fall," and it produces a sensation of weightlessness. Proper acceleration reduces to coordinate acceleration in an inertial coordinate system in flat spacetime (i.e. in the absence of gravity), provided the magnitude of the object's proper-velocity [ 3 ] (momentum per unit mass) is ...

  7. Wonders of the Universe - Wikipedia

    en.wikipedia.org/wiki/Wonders_of_the_Universe

    This episode documents how gravity has a profound effect across the universe, and Cox seeks out a non-space zero-gravity experience to highlight his point. From the formation of galaxies and stars to the patterns of uplift and erosion seen on Earth, gravity is centrally important.

  8. Air time (rides) - Wikipedia

    en.wikipedia.org/wiki/Air_time_(rides)

    Zero-G (where the net vertical G-force is 0) is achieved when the downward acceleration of the train is equal to that due to gravity; where the downward acceleration is greater, negative Gs arise. [citation needed] The zero-gravity roll is a roll specifically designed to create the effect of weightlessness and thereby produce air time.

  9. Astronaut training - Wikipedia

    en.wikipedia.org/wiki/Astronaut_training

    These efforts of simulating micro-gravity serve a similar purpose of creating an increasingly immersive environment for astronaut training. In fact, this is a developing trend for the entire VR industry. The ultimate scene VR experience that we are imagining will eventually be marked by the elimination between the real and the virtual world.
