In this follow-up to Dr. Maggie's Grand Tour of the Solar System, Dr. Maggie Alderin-Pocock answers some of kids' most pressing questions about the universe: What would happen if I fell into a black hole? Can I play soccer on Mars? Are there rainbows on other planets? It's everything children ages 8-12 could possibly want to know about the universe. The questions are grouped into loose thematic chapters, focusing on space and physics - broad subject areas such as "The Universe," "Our Solar System," and "Humans in Space" with the scope to cover a variety of topics such as stars, planets, other cosmic bodies, space-time, space exploration, alien life, spacecraft, and notable discoveries. Each chapter contains a selection of "big" questions - such as "What is a black hole?" - which can be unpacked with smaller sub-questions ("How are black holes made?" "Are they all the same size?"). This allows the reader to explore the science in more detail. The questions are also interspersed with very specific, quirky questions - like "What would happen to me if I fell into a black hole?" - with Dr. Maggie's signature, personal, conversational tone.
