Query: IF YOU WANT TO LEARN ABOUT ASTRONOMY AND COSMOLOGY DO NOT BUY THIS BOOK

I am a professional astronomer. I can tell you that there are serious problems with Jerome Drexler's theory and I agree strongly with the review given by JMK. For anyone interested in Cosmology, Dark Matter and Dark Energy, there are much better books out there, books that pain a picture of a more generally accepted theory.
