McDonald Observatory: Searching for Dark Energy

I note in the report "...the HETDEX "will tell us what makes up almost three-quarters of all the matter and energy in the universe. It will tell us if the laws of gravity are correct, and reveal new details about the Big Bang in which the universe was born," the HETDEX project website says." My note - the Big Bang model needs to explain the origin of many things, dark energy is an example and the origin of dark matter as well as the origin and existence of the primordial neutrinos. We have inflatons as well as magnetic monopolies and the multiverse model. There is the age of the universe using H0 constant based upon open universe vs. flat universe models, thus differences in Hubble time for the *beginning*. The Big Bang is getting very interesting :)
