School Library Journal - 04/01/2026 Gr 3–5—Readers who are curious about what will happen in the future of scientific pursuits will find plenty of possibilities in this series. Each book takes a premise, such as "Could we time travel?" and explores what is known so far and what may happen someday. Captivating images are balanced with text that explains how theories have been refined over time as science gathers more data and develops better tools. Sidebars compare the human brain to artificial intelligence or spotlight theorists like Stephen Hawking. After reviewing what is already known and what is being investigated or theorized, a final "what if" asks readers to consider the implications of future developments. A glossary, a list of suggested books and online resources, and an index round out each book. VERDICT The perfect books to hand to readers who are always asking what comes next. - Copyright 2026 Publishers Weekly, Library Journal and/or School Library Journal used with permission.
