I just found this via twitter:
Alan Guth on the BICEP2 Results - also indicates universe zero energy state-http://www.mit.edu/newsoffice/2014/3-q-alan-guth-on-new-insights-into-the-big-bang.html-The energy of a gravitational field is negative. As the patch expands at constant density, more and more energy, in the form of matter, is created. But at the same time, more and more negative energy appears in the form of the gravitational field that is filling the region. The total energy remains constant, as it must, and therefore remains very small. -It is possible that the total energy of the entire universe is exactly zero, with the positive energy of matter completely canceled by the negative energy of gravity. I often say that the universe is the ultimate free lunch, since it actually requires no energy to produce a universe.
