there's almost like a new force in the universe that selection drives complexification such to the point where systems can become self-governing self-referencing and when an object cares about its own existence in time it's on the way to life am i right in thinking that you're in scotland now yep i'm in glasgow given the fact that we might be talki...

Questions & Answers

Q: How does selection drive complexification and lead to the development of life?

Selection drives complexification by enabling systems to become self-governing and self-referencing. As objects care about their own existence in time, they develop memory and the ability to have a material influence on the future.

Q: What is the role of selection in the origin of life?

Selection plays a crucial role in the origin of life by allowing for the development of memory and the ability to build objects that cannot form by random chance. It is through selection that complex molecules and molecular machines can emerge.

Q: Could there be different forms of life, such as silicon-based life, in the universe?

It is possible that different forms of life exist in the universe, including silicon-based life. While silicon-based life would have different chemistry and characteristics, the principles of selection and complexification would still apply.

Q: How does the concept of time and entropy relate to the origin and development of life?

Time is essential for the development of life, as it allows for selection, memory, and the building of more sophisticated objects. While entropy is often associated with the idea of increasing disorder, Cronin suggests that expanding space and the asymmetry of time are more relevant factors.

Summary & Key Takeaways

• Lee Cronin explains the concept of selection in complexification, where systems become self-governing and self-referencing, leading to the development of life.

• He discusses the idea of life developing memory and the transition from non-life to cells via functional objects.

• Cronin explores the possibility of different forms of life in the universe, including silicon-based life and life in extreme environments.
