Do Christians disagree with the first law of thermodynamics?
Clearly, at the moment of the big bang, the first law of thermo dynamics was violated, if you can talk about physical laws as if they were applicable at time t=0. The cyclic universe is the only hypothesis under which energy could in any way be eternal, and, given current observations, that is not at present considered a tenable hypothesis. Other than that, most of her post is gobbledygook.
