EXCERPTS: Today, doubts about conventional explanations of life are growing and a wave of new general theories has emerged to better define our origins. These suggest that life doesn’t only depend on amino acids, DNA, proteins and other forms of matter. Today, it can be digitally simulated, biologically synthesised or made from entirely different materials to those that allowed our evolutionary ancestors to flourish. These and other possibilities are inviting researchers to ask more fundamental questions: if the materials for life can radically change – like the materials for computation – what stays the same? Are there deeper laws or principles that make life possible?
[...] more recent research suggests there are likely countless other possibilities for how life might emerge through potential chemical combinations. As the British chemist Lee Cronin, the American theoretical physicist Sara Walker and others have recently argued, seeking near-miraculous coincidences of chemistry can narrow our ability to find other processes meaningful to life. In fact, most chemical reactions, whether they take place on Earth or elsewhere in the Universe, are not connected to life. Chemistry alone is not enough to identify whether something is alive, which is why researchers seeking the origin of life must use other methods to make accurate judgments.
[...] Their proposals can be grouped into three distinct categories, three hypotheses, which we have named Tron, Golem and Maupertuis. The Tron hypothesis suggests that life can be simulated in software, without relying on the material conditions that gave rise to Earth’s living things. The Golem hypothesis suggests that life can be synthesised using different materials to those that first set our evolutionary history moving. And, if these two ideas are correct and life is not bound to the rare chemistry of Earth, we then have the Maupertuis hypothesis, the most radical of the three, which explores the fundamental laws involved in the origins of complex computational systems.
These hypotheses suggest that deep principles govern the emergence of problem-solving matter, principles that push our understanding of modern physics and chemistry towards their limits. They mark a radical departure from life as we once knew it. (MORE - missing details)
