Researchers at Queen Mary University of London have proposed a striking concept that links the deepest laws of physics to the existence of life itself. Their work suggests that the Universe’s fundamental constants sit inside an especially narrow range that enables liquids to flow in ways living cells rely upon. If those constants were even barely different, water, blood, and other life-supporting fluids could behave so otherwise that complex organisms might never have emerged in any respect.<\/p>\n
The study, published in Science Advances<\/em> in 2023, builds on earlier work by physicist Kostya Trachenko and colleagues showing that liquid viscosity is tied on to fundamental physical constants. That finding established a lower limit for the way “runny” liquids could be. The newer research prolonged the concept into biology, asking whether the identical physical rules that shape the cosmos may quietly determine whether cells can function.<\/p>\n Why Liquid Flow Matters for Life<\/strong><\/p>\n Life relies on movement at microscopic scales. Nutrients must travel through cells, proteins have to fold appropriately, and molecules consistently diffuse through watery environments. All of this relies on viscosity, the property that determines how easily a liquid flows.<\/p>\n In response to the researchers, the Universe appears to operate inside a surprisingly narrow “bio-friendly” window where viscosity and diffusion remain suitable for all times. If the constants governing physics shifted by only a couple of percent, liquids essential to biology could develop into dramatically thicker or thinner.<\/p>\n “Understanding how water flows in a cup seems to be closely related to the grand challenge to work out fundamental constants. Life processes in and between living cells require motion and it’s viscosity that sets the properties of this motion. If fundamental constants change, viscosity would change too impacting life as we realize it. For instance, if water was as viscous as tar life wouldn’t exist in its current form or not exist in any respect. This is applicable beyond water, so all life forms using the liquid state to operate could be affected.”<\/p>\n The team says the implications would extend far beyond drinking water or oceans. Human blood, cellular fluids, and the chemistry that powers life all depend on rigorously balanced flow properties.<\/p>\n “Any change in fundamental constants including a rise or decrease could be equally bad news for flow and for liquid-based life. We expect the window to be quite narrow: for instance, viscosity of our blood would develop into too thick or too thin for body functioning with only a couple of per cent change of some fundamental constants corresponding to the Planck constant or electron charge.” Professor of Physics Kostya Trachenko said.<\/p>\n A Recent Twist on Cosmic Wonderful-Tuning<\/strong><\/p>\n Physicists have long debated why the Universe’s constants appear finely tuned. Tiny differences in values corresponding to the electron charge or the strength of fundamental forces could prevent stars from forming heavy elements needed for planets and life.<\/p>\n What makes this research unusual is that it shifts the discussion from stars and galaxies right down to the extent of living cells. Previous fine-tuning arguments often focused on nuclear reactions inside stars. This work argues that even when stars and heavy elements still formed, life might remain inconceivable if liquids couldn’t flow properly inside organisms.<\/p>\n That introduces a second layer of fine-tuning. The constants not only appear compatible with a universe filled with matter, but in addition with biological systems that rely upon delicate liquid dynamics.<\/p>\n The researchers even suggest that multiple stages of tuning could have occurred. Within the paper, Trachenko compares the likelihood to biological evolution, where traits emerge independently over time. The concept stays speculative, but it surely raises the likelihood that nature may favor stable physical structures in ways scientists don’t yet fully understand.<\/p>\n Later Research Expanded the Idea<\/strong><\/p>\n Because the original publication, scientists have continued exploring how viscosity, diffusion, and fluid behavior connect with fundamental physics. Follow-up theoretical work reviewed how liquid motion inside cells may place additional limits on the values of physical constants, especially in systems involving biochemical “machines” corresponding to molecular motors.<\/p>\n Other researchers have also examined how viscosity itself may arise from deeper physical laws. A 2023 evaluation highlighted growing evidence that liquid viscosity could also be linked to universal physical limits relatively than simply being a property measured in laboratories.<\/p>\n Together, these studies are helping reshape an old scientific mystery. As a substitute of viewing the constants of nature only through the lens of cosmology and particle physics, scientists are increasingly asking whether the conditions needed for flowing liquids and functioning cells also needs to be a part of the equation.<\/p>\n Could Physics and Biology Be More Connected Than We Thought?<\/strong><\/p>\n The concept stays highly theoretical, and lots of physicists would caution that there continues to be no accepted explanation for why the constants of nature have their observed values. However the research opens an unexpected path for desirous about one in every of science’s biggest questions.<\/p>\n For many years, the mystery of fundamental constants was mostly explored through black holes, stars, and subatomic particles. This work suggests the reply may involve something much closer to on a regular basis life: the straightforward ability of liquids to flow through living cells.<\/p>\n<\/div>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Researchers at Queen Mary University of London have proposed a striking concept that links the deepest laws of physics to the existence of life itself.
