A Brief History of Time: From the Big Bang to Black Holes

Interesting but much too complicated for me to go through as an audio book!

While relatively short, and written in terms and descriptively that laymen are able to understand, I admit that at the end I retained little of what I learned (and convinced myself I grasped) on the way through.
Certainly at the start with the space time, elementary particles, black holes and even event horizons as I read I was able to nod along agreeing it made sense, but once we got into unification theory and string theory I expect I just looked more and more puzzled as I read.
This, of course, is my problem, and not a problem with the book, which was - as might be expected from Stephen Hawking - well organised, thorough and followed a logical progression.
As I read for entertainment and not necessary is a study mode, I can brush my lack of retaining detail of the book under the rug and move on relatively easily.
4 stars.

It took me a lot of time to finish it, but it's definitely worth the reading.
Hawking is targeting “average people” by simplifying cosmetics problems about existing, time and the boundaries of the universe(more like the gate of the knowledge of the mode of action of our universe).
A true scientific master piece to have on the shelf.
