Our improbable universe a physicist considers how we got here.

"Our Improbable Universe will show you why "ordinary existence" is really extraordinary. From the most practical point of view, we really are "star children": the iron in the blood in our veins originated in a stellar explosion billions of years ago. How likely is it that all the myriad conditions for life would come together so precisely? Without positing or denying the existence of a Creator behind it all, the answer to that question is humbling and fascinating. Along the way, Dr. Michael Mallary summarizes the latest findings in cosmology - including string theory, high energy physics, and relativity."--BOOK JACKET.
