I'm not in much of a hurry, and I have a very limited science background, so I wasn't sure if this would be the book for me. How wrong I was. Astrophysics for People in a Hurry helped expand my knowledge beyond our galaxy and into the universe (or universes) beyond. The author takes you to the end of time -- or is it the beginning? There is also the possibility that there really is no time at all; it's just a human construct to get the flight schedules on time. So it makes sense sometimes to not be in a hurry -- unless a bear is chasing you. The big bang theory is explained, as are the possible big bang theories to come. My writing is confusing because I'm a novice at astrophysics. But trust me, Neil DeGrasse Tyson will give you all the expertise you need in this universe, as well as the duplicate you in a parallel dimension. Happy space travels!
