Lee Cronin's Assembly Theory offers a way to find alien life by quantifying molecular complexity. Using mass spectrometry, scientists can search for molecules with a high 'assembly index,' a clear signature that they were constructed by an evolutionary process rather than random chemistry.

The principle of evolution extends beyond biology to inanimate systems like minerals, cities, and AI. All these systems tend toward greater complexity and pattern over time, with Darwin's theory being a specific application for living organisms with genetic transfer.

Conventional physics views the universe as evolving from initial conditions via fixed laws. An alternative view is that the universe is a self-constructing system with no external builder. Life is the physical process through which the universe explores possibilities and generates novelty.

Selection is not exclusive to biology. It is a fundamental physical force that acts on matter, favoring configurations that persist over time. This process of 'selfish matter' battling for persistence was happening long before the first cells emerged, making life a natural consequence of physics.

Cosmologists mistakenly model the universe with simple gas laws, as if it's a random bag of chemicals. Instead, it behaves like an evolving organism—"a dog"—that grows more complex and interesting over time. This fundamental mischaracterization leads to flawed theories.

This theory posits that the singularity of a black hole in a parent universe "bounces" to become the Big Bang of a child universe. Slight variations in physical constants are passed down, and universes that produce more black holes are more "reproductively successful," driving cosmic evolution.

A more effective way to define life is not by its internal components (like RNA or metabolism) but by its unique capability. Life is any system that can recursively produce many identical copies of highly complex objects, a feat only achievable through evolution.

Beyond optimizing existing biological functions, Frances Arnold's lab uses directed evolution to create enzymes for entirely new chemical reactions, like forming carbon-silicon bonds. This demonstrates that life's chemical toolkit is a small subset of what's possible, opening up a vast "non-natural" chemical universe.

Counterbalancing the well-known arrow of time (entropy and decay), a proposed new law of nature suggests a second arrow. This law describes the universe's inherent tendency to build greater pattern, complexity, and functional information in all evolving systems.
