We describe the universe as a local, inhomogeneous spherical bubble embedded in a flat matter dominated FLRW universe. Generalized exact Friedmann equations describe the expansion of the universe and an early universe inflationary de Sitter solution is obtained. A non-perturbative expression for the deceleration parameter q is derived that can possibly describe the acceleration of the universe without dark energy, due to the effects associated with very long wave length super-horizon… Expand

Cosmic acceleration driven by mirage inhomogeneities
A cosmological model based on an inhomogeneous D3-brane moving in an AdS5 × S5 bulk is introduced. Although there are no special points in the bulk, the brane universe has a centre and is isotropicExpand
Backreaction of inhomogeneities can mimic dark energy
In the standard approach to cosmology, the evolution and observations associated with an inhomogeneous universe with density p(x) are modeled by employing a homogeneous cosmological model of densityExpand
One-loop corrections to the curvature perturbation from inflation
An estimate of the one-loop correction to the power spectrum of the primordial curvature perturbation is given, assuming it is generated during a phase of single-field, slow-roll inflation. The loopExpand
Swiss cheese and a cheesy CMB
It has been argued that the Swiss-Cheese cosmology can mimic Dark Energy, when it comes to the observed luminosity distance-redshift relation. Besides the fact that this effect tends to disappear onExpand
