G-theory and its reduction to F(R)-gravity in FRW universe

Abstract

A new theory, named G(General)-theory in 14 dimensions, has been proposed that is reduced to [Formula: see text]-gravity and produces the metric of FRW universe in four dimensions. In this theory, the Universe is born in six stages. First, there is nothing in the world. Then, two strings, one with positive energy and one with negative energy in 14th, dimension are created such that the sum over their energies is zero. These strings are excited and for flowing their energies, other dimensions are produced. Second, these strings decay to G0-branes. Third, these branes join each other and construct Gp-branes which tensor fields live on. The rank of these fields can change from zero to p for [Formula: see text] and from zero to six for [Formula: see text]. Four, by compacting Gp-branes on three circles, supersymmetry is born which contains the equal number of degrees of freedom for fermions and bosons. Six, by reducing G-theory to four dimensions, FRW universe is emerges and initial tensor fields produce the predicted shape of [Formula: see text]-gravity.
