WebFeb 22, 2007 · The instability occurs if φ ″ = f ″ ( R) < 0 and if ϵ is very small, since the coefficient of the last term on the left-hand side of Eq. (6) is the square of an effective mass. As already mentioned in [14] it can be considered as an instability in the gravity sector. WebThis instability is exactly what is needed to explain the observation that the Universe is much more irregular now than at decoupling, and gravitational instability is almost universally accepted to be the primary influence leading to the formation of structures in …
