Black Holes: The Key to Understanding the Universe by Brian Cox, Jeff Forshaw

4.5

this was incredibly well done. so so informative and far reaching but never felt like it was doing too much. 
however this is definitely not a book for beginners! there is some maths (not too complex) but the physics like penrose diagrams and the holographic principle are HARD. having an understanding of relativity made the first third or so much easier, but the last third was mind boggling at times to say the least. i do prefer this over too much simplicity, but it was definitely a lot and some of the stuff remains very confusing.
