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.
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.
The Zero Gravity Research Facility at the NASA Glenn Research Center, in Cleveland, Ohio, is a unique facility designed to perform tests in a reduced gravity environment. It has successfully supported research for United States crewed spacecraft programs and numerous uncrewed projects.
Anti-gravity (also known as non-gravitational field) is the phenomenon of creating a place or object that is free from the force of gravity. It does not refer to either the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift ...
Since dust can not settle in zero gravity, small pieces of dead skin or metal can get in the eye, causing irritation and increasing the risk of infection. [88] Long spaceflights can also alter a space traveler's eye movements (particularly the vestibulo-ocular reflex). [89]
In fact, it can be enjoyable to have zero gravity in the cockpit. To produce 0g, the aircraft has to follow a ballistic flight path, which is essentially an upside down parabola. This is the only method to simulate zero gravity for humans on earth. In helicopters. In contrast, low-g conditions can be disastrous for helicopters.
The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero: its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity. [1]
Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.
