I like the proverbial "outside the box" thinking, and you don't get much more outside the box than this interpretation of patterns found in the cosmic background radiation. The beauty of science is that it is a well-constructed box we're trying to get outside of, and it is logical plausible thinking that gets us there. The math behind theories like this involves tensors and the like that my courses in partial differential equations touched on so many years ago, and that I was forced to play with on a graduate level in fluid dynamics somewhat later, but still also so many years ago. I neither remember any of it, nor knew it well at the time. Amazing stuff, this theoretical physics. Science does have all the answers. We just don't have all the science.
