How old is the Universe? How was it born? What is dark matter? Are the laws of physics universal? Is there life on Mars? Are there other universes? Without equations, this little course presents the 50 key ideas for understanding the Universe. Across 4 pages each, enriched with historical anecdotes and clear little diagrams, every section can be read independently of the others and requires no prior knowledge of mathematics.
