An inhomogeneous cosmology describing a spacetime without symmetry is shown to be able to inflate the early universe and explain the late-time acceleration of the universe without a cosmological constant and negative pressure dark energy and avoid the coincidence problem. e-mail: [email protected]

It is generally argued that the present cosmological observations support the accelerating models of the universe, as driven by the cosmological constant or 'dark energy'. We argue here that an alternative model of the universe is possible which explains the current observations of the universe. We demonstrate this with a reinterpretation of the magnitude-redshift relation for Type Ia supernova...

In this paper, we use the result in [7] to calculate the non-Gaussianity of the racetrack models in [3, 5]. The two models give different nonGaussianities. Both of them are reasonable. PACS: 98.80.Cq, 98.80.Jk, 04.20.Gz
