‘We are all time-travellers, journeying together into the future. Be brave. Be determined. Let's work together to make that future a place we want to visit.' Based on Stephen Hawking's 2018 Earth Day address, this picture book asks children everywhere to look up and wonder at the world around them - just as Professor Hawking did throughout his life. Includes questions and answers on some big science topics, explained for young readers by Professor Hawking's daughter, Lucy.
