The Cosmic Cocktail: Three Parts Dark Matter

Boring and repetitive. This is a poorly written book. I must have seen the phrase “dark energy is 70%” at least a dozen times. Chapter 9, which is supposed to discuss dark energy, never really gets around to defining it; Wikipedia can do it in one sentence. Also, why does the author constantly refer to her ex-fiance as “my ex-fiance”? Really, who cares?
