Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. [1] Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of ...
2022: The Mandalorian is shown on a rotating ring with artificial gravity in the Book of Boba Fett. 2022: The season 3 premiere of For All Mankind, an Apple TV+ original series, depicts a space hotel with a rotating wheel for gravity generation which becomes important to the storyline after the rotating mechanism malfunctions.
An O'Neill cylinder (also called an O'Neill colony) is a space settlement concept proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. [ 1 ] O'Neill proposed the colonization of space for the 21st century, using materials extracted from the Moon and later from asteroids. [ 2 ]
Diagram regarding the confirmation of gravitomagnetism by Gravity Probe B. Gravitoelectromagnetism, abbreviated GEM, refers to a set of formal analogies between the equations for electromagnetism and relativistic gravitation; specifically: between Maxwell's field equations and an approximation, valid under certain conditions, to the Einstein field equations for general relativity.
Because of physicists’ inability to square quantum theory with general relativity, this has led some to question whether gravity even acts like the other fundamental forces and if the graviton ...
Space travel under constant acceleration. Space travel under constant acceleration is a hypothetical method of space travel that involves the use of a propulsion system that generates a constant acceleration rather than the short, impulsive thrusts produced by traditional chemical rockets. For the first half of the journey the propulsion system ...
Efficiency measures. Propulsive maneuvers. v. t. e. Celestial mechanics is the branch of astronomy that deals with the motions of objects in outer space. Historically, celestial mechanics applies principles of physics (classical mechanics) to astronomical objects, such as stars and planets, to produce ephemeris data.
GRACE and GRACE-FO. The Gravity Recovery and Climate Experiment (GRACE) was a joint mission of NASA and the German Aerospace Center (DLR). Twin satellites took detailed measurements of Earth's gravity field anomalies from its launch in March 2002 to the end of its science mission in October 2017. The two satellites were sometimes called Tom and ...
