Researchers at Queen Mary University of London have proposed a striking idea that links the deepest laws of physics to the existence of life itself. Their work suggests that the Universe's fundamental constants sit within an extremely narrow range that allows liquids to flow in ways living cells depend on. If those constants were even slightly different, water, blood, and other life-supporting fluids could behave so differently that complex organisms might never have emerged at all. The study, published in Science Advances in 2023, builds on earlier work by physicist Kostya Trachenko and colleagues showing that liquid viscosity is tied directly to fundamental physical constants. That finding established a lower limit for how "runny" liquids can be. The newer research extended the idea into biology, asking whether the same physical rules that shape the cosmos may also quietly determine whether cells can function. Why Liquid Flow Matters for Life Life depends on movement at microscopic scales.…
