More Description

Recent discoveries in cosmologyâ¬cosmic inflation, primordial â¬Sripplesâ¬ý in spacetime, the accelerating expansion of the universe, dark energy, the possible existence of multiple universesâ¬have led to a bizarre new worldview that (to paraphrase Niels Bohr) may be just crazy enough to be true. Fortunately, the new cosmological advances also lead to testable predictions, and we may soon witness the confirmation of some of these predictions by fresh astronomical findings. The authorâ¬s own scientific work has been closely tied to the emergence of the new worldview, from the original ideas to the most recent developments. In this book, he gives an exciting, first-hand account of the birth of the new cosmology, and its fascinatingâ¬and at times disturbingâ¬implications.
