A world model in which our space-time is the result of a 3-brane moving through a space-time of higher dimension, with all interactions except gravity being confined to the 3-brane.
- ‘Cosmologists have picked up on this idea, and when they talk about the structure of the universe, you'll hear them talking about multi-dimensional ‘brane worlds’.’
- ‘The meeting gave an overview of the state of the art in brane world gravity, in a form accessible to non-experts and the many graduate students present.’
- ‘If the brane-world picture is correct, near the space of our planet a vast section of brane worlds exist.’
- ‘She leads us on to superstring theory and ‘brane worlds’, which picture particles as tiny vibrating filaments and the universe itself as a giant wobbly sheet.’
- ‘The force of gravity, which is free to pass between brane worlds, is far too feeble to interact strongly enough to produce the kind of localized effects often reported in paraphysics.’
