Abstract:Using a new kind of 5D Ricci-flat canonical metric, we obtain by a static foliation an effective 4D Schwarzschild -de Sitter hypersurface. We examine some particular initial conditions that could be responsible for the inflationary expansion of the early universe, which could be driven by the explosion of a white hole (WH). The zeroth-order spectrum outside the WH describes quantum fluctuations, which for a scale invariant power spectrum, can be expressed in terms of the cosmological constant, or the square ma… Show more
