🌌 Why Space Feels Cold Among So Many Suns: The Quiet Physics of Cosmic Warmth
From section: 🔥 How heat moves: conduction, convection, and radiation… Convection transports energy through the bulk motion of a fluid. Under gravity, buoyancy can cause warmer, less dense fluid to rise while cooler, denser fluid sinks, creating natural convection. …

The Cosmic Recipe: Understanding the Physical Criteria for Star Formation 🌟
From section: 💫 The dance of rotation… The infalling matter cannot simply collapse radially into a point. Much of it flattens into a rotating circumstellar disk around the growing protostar, where gravity, pressure, magnetic fields, turbulence, and orbital motion continue their negotiation.
