In the brane world scenarios, the reason we perceive only three spatial dimensions is that we live inside a 3-brane. There's a fundamental difference between the space dimensions on the brane and those off the brane.

Record 2 2023-10-17

English

Subject field(s)
  • Astrophysics and Cosmography
  • Space Physics
CONT

In theoretical physics, a brane ... is an object which can have any number of allowed dimensions. Branes are most popular for their presence in string theory, where it is a fundamental object, along with the string.

OBS

brane: While the designation comes from the term "membrane", the latter refers to a specific kind of brane (p-brane) and must not be used as a synonym for "brane."

  • Physique spatiale
CONT

[...] la théorie des cordes prédit l'existence d'objets étendus, appelés branes [...] dont le nombre de dimensions peut être de 0 (comme les particules), 1 (comme les cordes élémentaires), ou tout autre nombre jusqu'au nombre de dimensions spatiales lui-même.

OBS

brane : Bien que la désignation «brane» découle du terme «membrane», ce dernier désigne un type de précis de brane (p-brane) et ne constitue donc pas un synonyme de «brane».

CONT

In the original Randall-Sundrum model [the scientifics] propose a brane that sets the strength of gravity. In this gravitybrane, the strength of gravity is extremely large. As you move in a fifth dimension away from the gravitybrane, the strength of gravity drops exponentially.

[...] la création spontanée d'un monde branaire correspondrait à une histoire du temps imaginaire qui aurait la topologie d'une coquille de noix : cette histoire formerait une sphère quadridimensionnelle, comme la surface de la Terre, mais avec deux dimensions de plus.
