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.
