Talk:The universe's energy can't come from nothing (Talk.Origins)

I am concerned about the bounds of the integration used in this article. Can you please identify why you were justified in using the range from infinity to r₀ rather than integrating in the opposite direction?? I don't see any reason to integrate in reverse and the fact that you are doing this would apply a third minus sign that will result in a negative energy. In calculus integration is done from the lower bound to the higher bound. I have never encountered a situation where the assumption is that you are to integrate as you have done here.

If integration is performed as expected with the lower bound being r₀ then the result is a negative energy. And this whole article needs to be re-written and its conclusion corrected.
