The theoretical process by which an object approaching a black hole is progressively broken down into a long thin string of particles by increasing gravitational forces, especially the vast difference in gravitational strength at either end of the object.  3, record 1, English, - spaghettification

NASA's event horizon postcard warns travelers about visiting a black hole with a nod to "spaghettification, "also called the noodle effect. The closer an object gets to a black hole, the stronger its gravitational pull becomes.  4, record 1, English, - spaghettification

L'effet de lentille est dit fort lorsque la lumière est amplifiée et que plusieurs images de la source sont visibles, ou que l'image est tellement déformée que la source apparaît sous forme d'arcs lumineux. Lorsque la déviation est moins importante et l'image de la source seulement légèrement déformée, on parle d'effet de lentille gravitationnelle faible. L'intensité de l'effet dépend de la densité de masse : il est fort au cœur d'un amas de galaxies, et faible en périphérie.  1, record 2, French, - effet%20de%20lentille%20gravitationnelle%20faible

Les effets de lentille gravitationnelle sont utiles à plus d'un titre. Ils révèlent des objets trop peu lumineux pour être détectés par d'autres moyens, et permettent d'estimer la masse de l'objet constituant la lentille.  1, record 3, French, - effet%20de%20lentille%20gravitationnelle

Record number: 4, Textual support number: 1 OBS

The inner, visible part of the halo, which has roughly the same diameter as the galactic disk, is occupied by Population II objects, including globular clusters and old, individual stars. Beyond this is a much larger region, called the dark halo or extended halo, containing large amounts of dark matter, the presence of which is revealed by its gravitational effect on the galaxy's rotation. The nature of galactic dark matter is still undetermined but the most popular theory, supported by some recent observations, is that the dark halo is home to vast numbers of small, unseen bodies known as MACHOs.  3, record 4, English, - galactic%20halo

Le halo galactique est une région de l'espace entourant les galaxies spirales, et notamment notre Galaxie, la Voie lactée. On pense que le halo galactique est principalement constitué d'étoiles, de gaz et de matière noire. Dans une galaxie elliptique, il n'y a pas de transition nette entre le corps de la galaxie et le halo.  2, record 4, French, - halo%20galactique

GyroTorque Operating Principle. Gyroscopic reaction torque is generated when precessing a spinning rotor. A very common form of gyroscopic reaction is experienced when riding a bicycle, where the front wheel exhibits the properties of a gyroscopic rotor. If, as is too often the case, an off-balance torque is created by gravitational force, the rider intuitively counters the gravitational torque by turning the handle bar, which, in effect, amounts to precessing the rotor-like front wheel. The faster the bicycle is travelling, the greater is the spin of the front wheel and, hence, the smaller is the precession required to counter the off-balance torque. The operational advantages of GyroTorque result from a novel technique of generation and rectification of gyroscopic reaction torque from a rotor as it is applied to an input-independent output shaft.  1, record 5, English, - gyroscopic%20reaction%20torque

Cosmic travellers riding through the ether in their spacecraft might be as misled by mirages as thirsty nomads crossing the desert on camels. The microlensing that makes stars seem brighter has a big brother of an illusion : the so-called gravitational lensing of one entire galaxy's light by another one lying in the way. Rather than just brightening the resulting image, this effect distorts it. That turns out to be extremely useful for seeing dark matter.  1, record 7, English, - gravitational%20lensing
