(PhysOrg.com) -- "In many ways, the standard model of cosmology works very well," Jose Cembranos tells PhysOrg. "However, there are very basic features that we just do not know. We have dark energy and dark matter. They dictate the evolution of late time cosmology. They both together constitute more than 95 percent of the energy content of the present Universe." If this is the case, why do we trust the standard model? It can`t explain such a large portion of the universe.
