One thing about this project that I’m really pleased about is the fact that I read ‘A Briefer History of Time’ by Stephen Hawking and thoroughly enjoyed it. It made my head go a bit funny. It had never really occurred to me but apparently space and time began with the big bang. They’re both entirely relative. That fact in itself is pretty mad. Time moves more slowly when closer to a strong gravitational force. This is part of how a hypothetical astronaut who travelled through the universe at light speed would be younger than their twin on their return to earth.
