伦敦玛丽皇后大学物理学家科斯特亚·特拉琴科发现，宇宙基本物理常数与液体粘度之间存在关键联系，这一发现为解释生命为何能在宇宙中存在提供了新的科学视角。1研究表明，支持生命存在的物理条件不仅需要形成恒星和复杂化学物质，还需要液体具有特定的流动性质。1这项研究成果发表于《科学进展》2023年第9卷第34期。1
特拉琴科的研究显示，基本物理常数的微小变化会对液体粘度产生显著影响，进而阻碍生物学过程。1他指出"如果水像焦油一样粘稠，生命将不会以目前的形式存在或根本不存在"。1更具体地说，"血液粘度只需改变基本常数（如普朗克常数或电子电荷）的百分之几，就会变得过厚或过薄，无法维持身体功能"。1这意味着使生命能够存在的物理条件精密而脆弱。后续研究进一步探索了基本物理常数对血液等复杂生物流体的影响，相关成果发表于《欧洲物理学期刊E》2025年1月第48卷第1期。1
值得注意的是，这些生命友好的物理条件在生命细胞出现前数十亿年就已存在。1这提示宇宙的物理规律从根本上便与生命的可能性相适应。
Physicist Kostya Trachenko from Queen Mary University of London has identified a crucial connection between the universe's fundamental physical constants and the viscosity of liquids, offering new insight into why physical laws appear fine-tuned for life's existence 1. The research reveals that even minute variations in these constants—such as Planck's constant or electron charge—could render liquids either too thick or too thin to sustain biological processes 1.
According to Trachenko, "If water were as viscous as tar, life would not exist in its current form, or at all" 1. He further explained that blood viscosity would become either too thick or too thin to maintain bodily function with only a small percentage change in fundamental constants like Planck's constant or electron charge 1. The findings suggest that supporting life requires not only the formation of stars and complex chemistry, but also liquids with precisely calibrated flow properties 1. These life-friendly conditions existed billions of years before cellular life emerged 1.
The initial research was published in Science Advances in September 2023, Volume 9, Issue 34 1. Subsequent investigation into how fundamental constants affect complex biological fluids like blood appeared in the European Physical Journal E in January 2025, Volume 48, Issue 1 1.
