In 1998/99, Merab Gogberashvili published on arXiv a number of articles where he showed that if the Universe is considered as a thin shell (a mathematical synonym for "brane") expanding in 5-dimensional space then there is a possibility to obtain one scale for particle theory corresponding to the 5-dimensional cosmological constant and Universe ...
In physics, Randall–Sundrum models (also called 5-dimensional warped geometry theory) are models that describe the world in terms of a warped-geometry higher-dimensional universe, or more concretely as a 5-dimensional anti-de Sitter space where the elementary particles (except the graviton) are localized on a (3 + 1)-dimensional brane or branes.
The inflationary multiverse says that eternal cosmological inflation yields an enormous network of bubble universes, of which our universe would be one. The brane multiverse states that in M-theory, in the brane world scenario, our universe exists on one three-dimensional brane, which floats in a higher dimensional expanse potentially populated ...
The Dark Energy Spectroscopic Instrument (or DESI for short) has created the largest 3D map of the universe we’ve ever seen. DESI created the map over the course of seven months. Each month ...
The 20-year project could shed new light on how our universe expanded – and fill in a huge 'gap' in our history of the universe, scientists said. Biggest-ever 3D map of the universe unveiled ...
A point particle is a 0-brane, of dimension zero; a string, named after vibrating musical strings, is a 1-brane; a membrane, named after vibrating membranes such as drumheads, is a 2-brane. [2] The corresponding object of arbitrary dimension p is called a p-brane, a term coined by M. J. Duff et al. in 1988. [3]
Also, these surfaces can be mapped as branes. These branes can be viewed as objects with a morphism between them. In this case, the morphism will be the state of a string that stretches between brane A and brane B. Singularities are avoided because the observed consequences of "Big Crunches" never reach zero size. In fact, should the universe ...
Warped extra dimensions, such as those proposed by the Randall–Sundrum model (RS), based on warped geometry where the universe is a five-dimensional anti-de Sitter space and the elementary particles except for the graviton are localized on a (3 + 1)-dimensional brane or branes. [3]
