This is a no-nonsense look at the Big Bang theory with a large dose of current scientific theory and a small dose of modern philosophy.

I like how Krauss doesn’t pull his punches concerning either, yet he still manages to present his opinions with a wry sense of humor. Despite being a cutting-edge theoretical physicist, he doesn’t talk down to the reader; a layperson, as well as a scientist (me), can enjoy it. And I did!

This fine book addresses questions such as “How did the universe originate?" "Are there other universes (the Multiverse)?" "Why, after all, is there a universe?"

So, no energy was required to produce it: the universe can have been created out of Nothing! To understand how this would be possible, the author takes us to the wonders of quantum mechanics, which allow the universe to be created as a vacuum fluctuation in a space with more… show more.
