Takeaway: My brain is not designed for complex physics. But I keep reading anyway.
The premise of the book is fascinating. Physicist Michio Kaku takes science fiction ideas and objects and evaluates how they might work and how far away we are from being able to actually do what is now impossible.
Light Sabers, Warp Drives, faster than light travel, time travel, replicators are all in here. The closer Kaku is to the actual science fiction the more interesting the book is. The longer the description, the more side discussions the more I lost interest.
Kaku is a fairly good author. Much of the book was very well written and understandable. (I say this as someone that wants to understand science and frequently reads science but really does not understand it.) But it gets too detailed too often, especially about half way through the book.
