How to Build a Time Machine

Step inside the world of time travel with a curious middle-grade explorer who tackles the big ideas of gravity, black holes, and wormholes through simple experiments and projects. The book explains how scientists measure time and how the bends in space-time might one day allow us to move through moments. As each activity raises new questions, readers learn to build a miniature black-hole model and test the limits of what we know about the universe. This guide blends clear explanations with hands-on challenges, turning abstract concepts into something you can see and feel.
