The energy of the relativistic particles of the radio sources is so great that it must also have a gravitational origin. This must be in the same gas cloud that, earlier, powered the field and through which the field lines pass, as otherwise the particles would not be injected into the field.... Furthermore, the particle acceleration mechanism must be electromagnetic rather than by stellar explosions.... A model which appears to satisfy the requirements is the magnetic rotator or spinning plasma cloud with an oblique or orthogonal magnetic field. 1, record 1, English, - magnetic%20rotator

Comment la nature a-t-elle «construit» un rotateur capable d'inonder si longtemps l'Univers de flots d'énergie tellement puissants [...]? L'axe du champ magnétique du rotateur-magnétoïde ne coïncide pas avec son axe de rotation (ils forment un certain angle) [...]. Pénétrant dans la zone du rayonnement du dipôle magnétique de la super-étoile, [le plasma] devient accéléré jusqu'à des vitesse proches de celle de la lumière et, freiné dans le champ magnétique, commence à émettre des ondes électromagnétiques d'une puissance fantastique. 2, record 1, French, - rotateur

In an orbiting spacecraft, zero gravity is experienced as weightlessness. 7, record 2, English, - weightlessness
Record number: 2, Textual support number: 1 OBS
A condition of apparent absence of an acceleration field. This may be experienced during unopposed acceleration at that rate imposed by the gravitational field(e. g. free fall in a vacuum or within a closed vessel), when the gravitational force is countered by an equal and opposite force(as in orbital flight) or during flight at escape velocity. Partial simulation is commonly conducted by immersion in a liquid of specific gravity close to that of the body. 6, record 2, English, - weightlessness

L'impesanteur, dans le domaine de l'astronautique comme dans tout autre, est l'état d'un corps tel que l'ensemble des forces gravitationnelles et inertielles auxquelles il est soumis possède une résultante et un moment résultant nuls. L'impesanteur [...] est donc le phénomène ressenti en l'absence de pesanteur. L'impesanteur n'est donc pas provoquée par l'éloignement de la Terre ou de tout autre corps céleste attractif : l'accélération due à la gravité à une hauteur de 100 km par exemple n'est que de 4 % moindre qu'à la surface de la Terre. En réalité, l'impesanteur est ressentie lorsque l'accélération subie égale la gravité, ce qui recouvre aussi le cas où le champ de gravité serait nul, ce qui n'arrive pas puisque l'influence de la gravité est partout dans l'Univers. 8, record 2, French, - impesanteur

Se define ingravidez como el estado en el que un cuerpo tiene peso nulo. El motivo por el cual el peso se hace nulo es que la fuerza gravitatoria sea contrarrestada por la fuerza centrífuga (en un sistema de referencia solidario con el cuerpo) o por alguna fuerza de igual intensidad que el peso, pero que actúe en la dirección opuesta. 1, record 2, Spanish, - ingravidez

An incoming photon of energy... entering an atomic cluster will join a partner of Opposite Parity... from one of the outermost rings of particles. The partner will be taken for a "plunge". It is compressed "in steps", while spiraling together at a gradually increasing velocity, under the influence of the gravitational field acceleration. The kernel gains energy from the gravitational field. 1, record 3, English, - gravitational%20field%20acceleration

[...] Considérons : un véhicule habité So, de masse Mo, de centre d'inertie Go; un astronaute S de masse P, de centre d'inertie G à proximité immédiate de So (dedans ou dehors). On suppose qu'à un instant initial to, S et So ont même vitesse absolue et ne sont pas en interaction. On note ro(t) et r(t) = ro(t) + R(t) les rayons vecteurs des 2 mobiles. F est l'accélération du champ de gravitation au rayon ro(t). 1, record 3, French, - acc%C3%A9l%C3%A9ration%20du%20champ%20de%20gravitation
