‘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 Professor Hawking’s 2018 Earth Day address, this inspiring picture asks children everywhere to look up and wonder at the world around them – just as Professor Hawking did his whole life. Including questions and answers to some big science topics, perfectly explained for young readers by Professor Hawking’s daughter, Lucy, and beautifully illustrated by Xin Li, this is the perfect read for curious minds.
