Life's Flow: New Fine-Tuning Hypothesis Links Constants to Cellular Fluid Dynamics
A Queen Mary University of London team proposes that the Universe’s fundamental constants lie in a narrow range that keeps liquids—like water and blood—flowing in a way compatible with life. Even small changes could drastically alter viscosity and diffusion, potentially preventing cellular processes and life as we know it. Building on earlier work linking viscosity to physical limits, the study adds a biology-focused angle to the fine-tuning discussion, suggesting a possible second layer of tuning that governs whether life can emerge. While theoretical and speculative, follow-up work is exploring how cellular liquid motion could constrain constants and reflect deeper connections between physics and biology.
