. Dropping the assumption of flatnessand using priors from the HST Key Project and Big-Bang nucleosynthesis only,we find a negative deceleration parameter q0 at 94.3%confidence from thetomographic lensing analysis, providing independent evidence of the accelerated expansion of the Universe.For a flat...

There is compelling evidence, nowadays, that the present expansion of the Universe is accelerated. In Einstein gravity this acceleration is explained by invoking some exotic energy component with a huge negative pressure. More general gravity theories simply modify the Einsteinu2013Hilbert action in ad...
We pre- sent new geometric equations relating brightness dimming and redshift, and employ them to fully explain the erroneous reasoning and erroneous conclu- sions of Perlmutter, Schmidt, Riess and the 2011 Nobel Prize Committee re- garding "accelerated expansion" of the Universe. We demonstrate ...

We explore the viability of a bulk viscous matter-dominated Universe to explain the present accelerated expansion of the Universe. The model is composed by two fluids: a radiation component and a pressureless fluid with bulk viscosity of the form zeta = zeta_0 + zeta_1 H where zeta_0 and ...
