Sounds good to me,…it provides a neat explanation of the basic mechanics that could be behind the mysterious transition period. (Gravitational attraction to Dark Energy repulsion)
General Relativity seems to describe Gravity, not so much as a force, but as an effect of the deformation of space/time, caused by the local presence of large (Dense) accumulations of (Normal) matter.
Recently, The Wilkinson Microwave Anisotropy Probe (WMAP) indicated that something on the order of 73% of the total mass of the observable Universe, is composed of Dark Matter. About the only thing that can be said definitively about Dark Matter, is that (from our perspective) it does not appear to radiate in the EM spectrum.
Why?
