That has profound implications for the role of God as Creator?

What does "that" refer to?
Does it refer to "the universe is completely self-contained, with no singularities or boundaries,and completely described by a unified theory"?

Context:

When we combine quantum mechanics with general relativity, there seems to be a new possibility that did not arise before: that space and time together might form a finite, four-dimensional space without singularities or boundaries, like the surface of the earth but with more dimensions. It seems that this idea could explain many of the observed features of the universe, such as its large-scale uniformity and also the smaller-scale departures from homogeneity, like galaxies, stars, and even human beings. It could even account for the arrow of time that we observe. But if the universe is completely self-contained, with no singularities or boundaries,and completely described by a unified theory, that has profound implications for the role of God as Creator.
