From the big bang to black holes, from the origins of the universe to the multiverse, Roberto Trotta tells the story of the most important discoveries and mysteries in modern cosmology, with a twist. Setting himself a unique challenge, Trotta limits his lexicon to the thousand most common words in the English language—excluding "physics," "energy," "galaxy," or even "universe." Through the eyes of a fictional scientist (Student-People) hunting for dark matter with one of the biggest telescopes (Big-Seers) on Earth (Home-World), this London-based cosmologist explores the most important ideas about our universe (All-there-is) in language simple enough for anyone to understand.
