Darell School in Kew had a remarkable visitor last week. Lucy Hawking is the author of children's books including George and the Blue Moon and has written others with her father, Professor Stephen Hawking.
After a special science assembly, she toured the whole school looking at the range of its science teaching and bravely volunteered to answer any questions the Darell children could think of.
These included: "When a person goes into a black hole, do they really turn into spaghetti?", "Which planet could we move to if Earth gets too polluted?", and, from year two, "When will the universe end?"
Happily, the answer to the last one, says Lucy Hawking, is: not for another five billion years, meaning that Easter at least is safe.
