These essays were very thought provoking and easy to understand. Sometimes astronomy and physics is too abstract for me to conceptualize but Alan Lightman does a good job of explaining the way of things and tying theories and ideas together. I especially enjoyed "the Accidental Universe" and "the Gargantuan Universe," which focus more on theories related to space. The other essays have a more spiritual or philosophical approach, which I enjoyed too, but not as much. All in all, an easy and fun read.
