Outline
● Cosmic Microwave Background Radiation● Einstein – Strauss - de Sitter vakuola model● Refraction of light at the matching hypersurface● Meszáros – Molnár model of temperature
fluctuations● Results and Concluding remarks
Temperature Fluctuations of CMBR
● Last Scattering Surface (z=1600)● Sachs-Wolfe effect● Voids, Clusters (z=2)● Rees-Sciama effect
Einstein-Strauss-de Sitter vakuola model
● Dust filled homogeneous and isotropic universe.
● Extract a sphere of mass M● Replace by Schwarzchild-de Sitter black hole
spacetime of the same mass.● Synchronize the cosmic time with the proper
time of observers co-moving with matching hypersurface.
Einstein-Strauss-de Sitter vakuola model
Schwarzchild-de Sitter:
Friedmanian geometry:
Einstein-Strauss-de Sitter vakuola model
Synchronization of proper time of radial geodesics and cosmic time T.
