The Big Crunch is one of the scenarios predicted by scientists in which the Universe may end. Just like many others, it is based on Einstein's theory of general relativity. That is, if the Big Bang describes how the Universe most possibly began, the Big Crunch describes how it will end as a consequence of that beginning.  3, record 1, English, - Big%20Crunch

A theoretically deduced particle postulated as the quantum of the gravitational field, having a rest mass and charge of zero and a spin of 2.  2, record 2, English, - graviton

Record number: 2, Textual support number: 1 CONT

Many physicists assume that gravitons exist, but few think that we will ever see them. These hypothetical elementary particles are a cornerstone of theories of quantum gravity, which seek to unify Albert Einstein's general theory of relativity with quantum mechanics. But they are notoriously hard — perhaps impossible — to observe in nature.  3, record 2, English, - graviton

String theory is one of the proposed methods for producing a theory of everything, a model that describes all known particles and forces and that would supersede the standard model of physics, which can explain everything except gravity.  3, record 3, English, - string%20theory

On comprend qu'une théorie qui unifierait le modèle standard et la relativité générale, et qui expliquerait les quatre forces, constituerait dès lors une sorte de graal de la physique – on en parle même parfois comme d'une théorie du tout. Telle est précisément l'ambition de la théorie des cordes.  3, record 3, French, - th%C3%A9orie%20des%20cordes

Le gyrolaser, contrairement au gyroscope mécanique, ne comporte aucune pièce mobile, et s'affranchit donc des erreurs dues aux frottements et aux défauts des liaisons mécaniques. Ainsi son facteur d'échelle k_g est inférieur à 10^-5 contre 10^-3 pour le gyroscope classique.  2, record 5, French, - gyroscope%20non%20classique

a theory asserting that the laws of physics are identical in all inertial frames. It follows that the speed of light cannot be different in different frames, even if they are in relative motion. Thus the speed of light is a universal constant. Special relativity predicts a number of effects such as time dilation, length contraction and mass increases.  1, record 7, English, - special%20theory%20of%20relativity
