What is time? How did it begin, and where will it end? Is time travel possible? How does the universe expand, and where do black holes come from? Junior Chicken and Alexis, the Quantum Cat, examine these and other extraordinary concepts, explaining the substance of Stephen Hawking's A Brief History of Time in terms that "even a chicken can understand." This humorous graphic novel–style exploration of cosmology and quantum physics will amuse and enlighten curious folk of all ages. Author John Gribbin received his PhD in astrophysics from the University of Cambridge and has written more than 120 popular science books, many of them science fiction. He swears on Einstein's socks that every word in this book — fantastic as it seems — is true. Artist Kate Charlesworth's extensive and diverse career in illustration includes a cartoon strip for New Scientist, "Life, the Universe and (Almost) Everything."
