Scientists make stunning discovery that could help explain why life exists

Key Points:

• Scientists led by Kostya Trachenko discovered that fundamental physical constants must allow liquids to flow in ways that support life, linking the laws of physics to biological viability.
• Their study shows that small changes in constants like the Planck constant or electron charge could drastically alter fluid viscosity, disrupting essential processes such as nutrient transport and diffusion in cells.
• This research suggests that the range of physical constants compatible with liquid-based life is narrow, implying life’s existence depends on finely tuned universal parameters beyond just star and element formation.
• Follow-up work revealed that blood viscosity, despite its complexity, aligns closely with theoretical values derived from fundamental constants, highlighting intricate molecular and quantum effects in biological fluids.
• The findings raise profound questions about why physical constants have life-supporting values and propose that multiple fine-tuning requirements or evolutionary principles might explain the universe’s suitability for life.
