Researchers at Queen Mary University of London found that the fundamental laws of physics are linked to the existence of life. They showed that if these constants were even slightly different, liquids essential to biology could behave in ways that would prevent complex organisms from emerging.

The researchers 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.

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.

According to the researchers, the Universe appears to operate within a surprisingly narrow 'bio-friendly' window where viscosity and diffusion remain suitable for life. If the constants governing physics shifted by only a few percent, liquids essential to biology could become dramatically thicker or thinner.

The team says the consequences would extend far beyond drinking water or oceans. Human blood, cellular fluids, and the chemistry that powers life all rely on carefully balanced flow properties.

Why It Matters

This discovery can help us understand why the universe is so 'fine-tuned' for life to exist. It also raises questions about whether nature favors stable physical structures in ways scientists do not yet fully understand.
