“Sky Rains Diamonds” explores the intriguing possibility of diamond formation within the ice giants Uranus and Neptune. It delves into the extreme conditions present within these planets, where immense pressure breaks down hydrocarbon molecules, freeing carbon atoms that then form diamond structures. These diamonds, heavier than the surrounding material, then “rain” down towards the planet's core. This process could significantly impact the planet’s thermal evolution and magnetic field generation, challenging our understanding of planetary interiors and geochemistry.
The book begins by establishing a foundation in planetary science, detailing the internal structure and atmospheric composition of Uranus and Neptune. It progresses to explore the experimental and theoretical research, including diamond anvil cell experiments and computer simulations, used to simulate the extreme pressures within these ice giants.
The book uniquely connects material science, astrophysics, and geochemistry to build a comprehensive argument, making it valuable for science enthusiasts seeking to expand their knowledge of planetary evolution and the novel carbon cycle occurring in these extreme environments.
