High-Gravity Worlds: The Planets That Crush You

Crystals are not alive, yet they grow, form complex structures, and even conduct electricity. Could life emerge from crystals rather than carbon-based molecules? Eexplore the intriguing possibility of crystal-based lifeforms, the challenges they would face, and the conditions where they might thrive. We journey to five exotic worlds—Vulcan, Ribbon World, Longenacht, Telluride, and Tempest—each offering unique environments where crystalline life might take hold. Could such life develop naturally, or might humanity one day engineer it? Join us as we dive into the cutting-edge science and speculative possibilities of crystalline biology.
