What Is Life? Is Death Real?

TL;DR

Life is about order, reactions, DNA, and information, blurring lines between living and dead matter.

Transcript

Life is fundamentally different from dead stuff—or is it? Physicist Erwin Schrödinger defined life this way: Living things avoid decay into disorder and equilibrium. What does this mean? Let’s pretend that your download folder is the universe. It started orderly and got more and more chaotic over time. By investing energy, you can create order and ... Read More

Questions & Answers

Q: What defines life according to physicist Erwin Schrödinger?

Schrödinger defines life as the avoidance of decay into disorder and equilibrium, where living things invest energy to create and maintain order.

Q: How do cells embody the properties we associate with life?

Cells have a wall for separation, self-regulate, consume nutrients, grow, react, evolve, and reproduce, yet no part of a cell is considered alive.

Q: What role does DNA play in the concept of life?

DNA carries genetic information, evolving and allowing the best living entities to survive, making it a crucial aspect of life as a carrier of genetic information.

Q: How do mitochondria blur the line between living and dead matter?

Mitochondria, once free-living bacteria, entered a symbiotic partnership with cells, showcasing how living things can evolve into dead entities while preserving genetic material.

Summary & Key Takeaways

• Life entails maintaining order and reacting to the environment.

• Cells, the building blocks of life, are intricate protein-based entities.

• DNA, viruses, AI, and complex processes challenge the definition of life.
