Query: This Has Nothing To Do WIth FTL Travel

I thought this might be another FTL travel speculation book when I picked it up. I was very dissapointed to learn the book has almost nothing to say about FTL travel at all. Instead this is an attempt to convey a theory other than inflation to explain how the universe got from the big bang to the state we see today.The first half of the book is a good recap of the theories os inflation and general and special relativity. This part of the book is well written, concrete, and easy to follow. The second half of the book is very dissapointing. It starts to get very squishy in a hurry. After reading it I had no idea what the theory was or what it stood for, other than being a direct frontal assault on Einstein's work. The second half of the book is filled with rants about other scientists, journal editors, and university administrators, but there is very little science.I think that without a catchy title, this book would never have been printed at all.
