The Edge of Knowledge: Unsolved Mysteries of the Cosmos

Three of the most important words in science are “I don’t know.” Not knowing implies a Universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last five hundred years, yet many fundamental mysteries of existence persist:  How did our Universe begin? How big is the Universe? Is time travel possible? What’s at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it?

From the review by RXTT’s Book Journey

“I hope that this book receives a very wide readership, for it is as equally valuable to a young scientist as it is to a layperson interested in big ideas.Our world bounces back and forth from close-minded totalitarian fundamentalism to wide-open progressive ideals.It is very easy for a society to lose ground, to lose hard-earned knowledge and wisdom, because someone, or something, claims to know all the answers.Beware of anyone telling you to stop asking questions.RUN AWAY from anyone telling there are no new answers out there and we already know all we need to know.They are Liars and con-artists and only seek to control you so they can line their pockets.Find those among us who are kind, who seek new answers and new questions, who understand that, for all we know as humans, our knowledge is dwarfed by the vast amounts we do not know.Lawrence M. Krauss has crafted an amazing book, one that not only tells us what we know and how, but informs us of what we have yet to find out. I highly recommend it.”
