“Modern cosmology is full of mind-bending ideas. Carlos Calle’s new book takes you through a whirlwind tour of the best of them, from strings and branes to the wave function of the universe. It’s a spirited, accessible introduction, and you’ll never look at the universe the same way again.”

Dr. Sean Carroll, theoretical physicist at California Institute of Technology and author of From Eternity to Hear

“In this excellent book, NASA physicist Carlos Calle tackles the question of whether the universe requires a supernatural ”designer” or whether our cosmological theories can explain the wondrous reality around us.

Marcus Chown, New Scientist, 16 May 2009

In his new book, Calle lays out the cosmological models based on M-theory, which suggest that our particular universe may be one of an unimaginable number of universes, each with its own set of physical laws. According to one of the most promising models, the big bang may not be the moment of creation but the bridge to a past filled with endless cycles of universe creation and destruction.
