Brane Universes Tested by Supernovae
We discuss observational constrains coming from supernovae Ia imposed on the behavior of the Randall-Sundrum models. It is interesting that brane models predict brighter galaxies for such redshifts which is in agreement with the measurement of the z = 1.7 supernova. We also demonstrate that the fit to supernovae data can also be obtained, if we admit the “super-negative” dark energy p = −(4/3)ϱ on the brane, where the dark energy in a way mimics the influence of the cosmological constant.
