Study Links Universe's Fundamental Constants to Biological Liquid Flow

Researchers at Queen Mary University of London have published a study suggesting that the existence of life depends on a narrow range of the Universe's fundamental physical constants. Published in Science Advances, the research indicates that these constants create a specific 'sweet spot' for liquid viscosity, which is critical for cellular function. If constants such as the Planck constant or electron charge were slightly different, essential biological fluids like water and blood could become too thick or too thin, rendering life impossible. This finding adds a new layer to the debate on cosmic fine-tuning, shifting focus from stellar formation to microscopic biological processes. The study argues that even if stars and heavy elements formed correctly, life might still fail to emerge if liquid dynamics within cells were disrupted. Professor Kostya Trachenko highlights that this delicate balance affects all life forms relying on liquid states, implying that multiple stages of physical tuning may be necessary for biology to exist. This discovery potentially reshapes our understanding of why the Universe appears uniquely suited for life.
