center-of-gravity travel
1center-of-gravity travel — The fore and aft movement of the center of gravity in the course of flight as a result of the consumption of fuel and the release of armaments and other stores. See center of gravity envelope …
2Center of population — with a mean distance of convert|5000|km|sigfig=1|sp=us. Its antipodal point is correspondingly the farthest point from everyone on earth, and is located in the South Pacific near 15000|km|sp=us.In demographics, the center of population of a… …
3center of pressure — An aerodynamically determined point at which wind force on the side of a vehicle is assumed to be concentrated for analytical purposes. It is a function of the shape and aerodynamic drag (resistance) of an automobile s body shell, determines the… …
4Travel to the Earth's center — Travel to the Earth s center, though not currently considered scientifically possible, is a popular theme in science fiction. Some subterranean fiction involves travel to the Earth s center, either finding a Hollow Earth or the Earth s molten… …

6Gravity model of migration — The Gravity model of migration, which is derived from Newton s law of gravity, is used to predict the degree of interaction between two places. Newton s law states that: Any two bodies attract one another with a force that is proportional to the… …
7Time travel — This article details time travel itself. For other uses, see Time Traveler. Time travel is the concept of moving between different moments in time in a manner analogous to moving between different points in space, either sending objects (or in… …
8Artificial gravity — is a simulation of gravity in outer space or free fall. Artificial gravity is desirable for long term space travel for ease of mobility and to avoid the adverse health effects of weightlessness.MethodsArtificial gravity could be created in… …
9Interstellar travel — Montage of fusion powered rocket concepts from 1987–2004, which could form the basis for an interstellar vehicle. Included are: VISTA (Lawrence Livermore National Laboratories,1987), Discovery II (NASA/GRC, 2002), Human Outer Planet Exploration… …
10United States gravity control propulsion research (1955 - 1974) — American interest in gravity control propulsion research intensified during the early 1950s. Literature from that period used the terms anti gravity, anti gravitation, baricentric, counterbary, electrogravitics, G projects, gravitics, gravity… …
