“You stop, and you turn back into stars. Mum says everyone’s made of stars. Is that true?’ ‘Yes,’ he said, and liked Anna even more than before. ‘All matter is forged by nuclear fusion reactions in the hearts of stars. They take hydrogen atoms, which are the littlest bits of the stuff the world is made of, and they bolt them together into bigger and bigger atoms – helium, oxygen, carbon, everything. All the atoms that make you. You’re star dust.’ She looked pleased with that. ‘And then when my atoms have finished being me, they go off back to the stars?’ ‘Some of them will be rain, some will be earth, some will float away and light up when the solar wind comes, and that makes the aurora. And like you say, some of them will find their way back into a star.”
