Professor Stephen Hawking left an enduring legacy, not only in the scientific journals, but in the hearts and minds of everyday people throughout the world. Despiteliving most of his life with a rare form of motor neurone disease that left him unable to communicate without specialist aid, Hawking's landmark books, such as A Brief History of Time and The Theory of Everything, became bestsellers across the globe (and perhaps even spacetime?).
The great scientist's final book, Brief Answers to the Big Questions, features some of his lasting thoughts about the biggest questions still left unanswered about the Universe. To celebrate the release of the paperback, PhD student Josh Kirklin has set some fiendishly difficult puzzles based upon the big questions for you to solve.
Answer these riddles below and find out if you're smart enough to rub shoulders with one of the most brilliant minds of a generation.
