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 ...
The Big Bang model does not fully explain the origin of the universe. It does not describe how energy, time, and space were caused, but rather it describes the emergence of the present universe from an ultra-dense and high-temperature initial state.
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]
The model is a braneworld theory developed while trying to solve the hierarchy problem of the Standard Model.It involves a finite five-dimensional bulk that is extremely warped and contains two branes: the Planckbrane (where gravity is a relatively strong force; also called "Gravitybrane") and the Tevbrane (our home with the Standard Model particles; also called "Weakbrane").
He joined the Hong Kong University of Science and Technology in 2011 and was the Director of HKUST Jockey Club Institute for Advanced Study during 2011-2016. [3] Together with Gia Dvali, he suggested the idea of brane inflation in 1998 in which inflation arises because of the weak forces supersymmetry allows between identical branes. [4]
Chapter 13, "The Universe on a Brane", expands on ideas from chapter 12, particularly on M-theory, of which string theory is a branch. This chapter is devoted to speculations on space and time. The insights of a number of physicists, including Edward Witten and Paul Dirac, are presented. The focus of the chapter becomes gravity and its ...
The word brane comes from the word "membrane" which refers to a two-dimensional brane. [27] Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics. They have mass and can have other attributes such as charge. A p-brane sweeps out a (p+1)-dimensional volume in spacetime called its worldvolume.
The simulated multiverse implies that technological leaps suggest that the universe is just a simulation. The ultimate multiverse is the ultimate theory, saying the principle of fecundity asserts that every possible universe is a real universe, thereby obviating the question of why one possibility – ours – is special. These universes ...
