Scientists Discover Why Life Exists on Earth

Topic: Physics

Physicist Kostya Trachenko found a connection between fundamental laws of physics and life's existence. He discovered that small changes to physical constants can affect how liquids flow, impacting essential biological processes.

Imagine a universe where stars still shine, planets form, and water exists, but liquids are so thick that living cells can barely function.

Scientists have made a stunning discovery that could help explain why life exists on Earth. Physicist Kostya Trachenko at Queen Mary University of London analyzed the fundamental laws of physics and found a surprising connection to the ability of life to exist.

He discovered that even relatively small changes to some of the universe's most basic physical constants can dramatically alter how liquids flow, potentially preventing essential biological processes from taking place. This means that if water was as thick as tar, life would not exist in its current form or might not exist at all.

Trachenko's study, published in Science Advances, raises a profound question about the universe: Why do the fundamental laws of nature have values that appear so well suited to the existence of life?

The discovery is based on an analysis of fundamental physical constants, which are numbers that govern how the universe operates. These constants influence everything from the behavior of atoms and chemical bonds to the nuclear reactions that power stars and produce elements essential for life.

Trachenko's research built upon his previous work in 2020, where he demonstrated that fundamental physical constants place a lower limit on the viscosity of liquids. Viscosity describes how strongly a fluid resists flowing.

In the new study, Trachenko examined the implications of this connection for biology and found that tiny changes to physics could make life impossible.

Why It Matters

This discovery can help us understand why life exists on Earth and potentially elsewhere in the universe. It also raises questions about the fundamental laws of nature and their relationship to life.
