Here’s a more detailed summary of the talk Anita Goel — “Towards A New Physics of Living Systems and Consciousness”, covering main arguments, experiment, implications and open questions.

1. Background & Motivation

• Goel is both a physicist and physician, which gives her a dual‑perspective on life/biology and fundamental physics.  
• She begins with the observation that much of physics has been developed for inanimate, near‑equilibrium, closed systems; living systems are quite different (open, non‑equilibrium, adaptive).  
• She poses: Could it be that living systems (cells, molecular machines) follow physical principles not yet captured by standard physics? And could consciousness be a phenomenon that demands such a new framework?
• The key motivation: To bridge biology + physics + information in a way that treats “life” and “consciousness” not as after‑thoughts but as central to the physical description of reality.

2. Key experimental / conceptual idea

• One of Goel’s central ideas: At the nanoscale, the “molecular machines” in cells (for example those reading/writing DNA, or other biomolecular complexes) might exhibit behaviours analogous to quantum/coherent phenomena — not just classical biochemical kinetics.  
• She refers to designing (or proposing) an analog of the famous “double slit” experiment in a living system. The idea is: if you can prepare a biological nano‑machine such that it exhibits interference/coherence effects (analogous to quantum systems), then one might infer that life uses quantum information processes, not just classical.  
• In doing so, she suggests a shift: rather than seeing biomolecules as passive “machines” in the classical sense, they might instead be “agents” in a more fundamental physical sense — where information, energy, and matter are deeply intertwined.
• She emphasises the role of information (not just matter/energy) in living systems: how information is processed, stored, transferred, and how it may require new physical laws to account for the coupling between matter, energy and information in an open, adaptive system.  

3. Core arguments

• Living Systems Are Far From Equilibrium & Open: She argues that life is characterised by continuous exchange of matter, energy, information with its environment (metabolism, adaptation, repair, growth) — and standard physics often focuses on closed systems or near‐equilibrium approximations.
• Molecular Machines as Quantum/Coherent Systems: The behaviour of biomolecules (enzymes, ribosomes, DNA‐machinery) might not always obey purely classical stochastic models; some phenomena might reflect coherence, superposition, or entanglement (or at least generalised information physics) in a living context.
• Consciousness as Physical, Not Emergent in the Usual Sense: In conventional neuroscience/biology, consciousness is often treated as a by‐product of neural complexity. Goel offers: what if consciousness is intrinsic to living systems at all levels (even molecular), and thus any physics of life must integrate consciousness (or proto‑consciousness) rather than treat it as an epiphenomenon.
• Need for a New Physics: Because these living systems:
  
• Are open and adaptive
• Process information in complex ways
• Possibly leverage quantum/coherent effects
• Might require a unity of matter/energy/information/consciousness
  So, she argues, we may need a “new physics” (or extension of existing physics) that can incorporate these features — not just physics of particles/fields, but physics of information + agency + life.
• 
  
• Paradigm Shift in How We View Life & the Universe: She suggests that maybe the universe is less like a machine and more like a living system; that life is not an afterthought but a fundamental aspect of reality. (As noted in commentary: “What if the universe is alive?”)  

4. Implications & Applications

• For Biology & Medicine: If molecular machines leverage quantum/information‑physics, then understanding them purely classically might be insufficient — this could open new therapeutic/diagnostic paths.
• For Consciousness Studies: Offers a route to integrate physics + biology + consciousness research: Instead of treating consciousness as outside physics, treat it as central.
• For Fundamental Physics: Suggests that physics might need to become more inclusive: incorporate life, information, adaptation, perhaps even purpose. It hints at bridging reductionist physics with holistic perspectives.
• For Technology / AI / Nanotech: The analogy of living‐machines at nanoscale suggests future nanotechnologies might more closely emulate “living” behaviour (self‐repair, adaptation, information‐driven dynamics) rather than just be mechanical.

5. Open Questions & Challenges

• Empirical Evidence: While the proposal is bold, demonstrating robust quantum/coherent effects in living molecular machines remains very challenging. Q: Can the proposed “double slit in a living system” be realised? What are the noise/decoherence issues?
• Distinguishing Classical vs “Quantum/Information” Effects: How to rigorously show that a biomolecular process is not just classical stochastic dynamics but genuinely uses quantum coherence or equivalent?
• What Is Consciousness Physically?: Even with a new physics of life, the step to “consciousness” remains deeply puzzling: what is it, how does it relate to molecular/nanoscale processes, how does it scale to brain/network level?
• Mathematical Framework: Developing a formal theory (with predictive power) that unifies matter‑energy‑information‑life‑consciousness is enormous. What are the equations? What are the testable predictions?
• Philosophical Implications: If life/consciousness become central in physics, this raises paradigm questions: teleology? agency? how to avoid anthropomorphism? How to keep it scientifically rigorous?

6. Conclusion

In summary:

Goel invites us to rethink conventional boundaries. Life is not just chemistry emergent on top of physics; it may require new physics. And consciousness may not be a mere epiphenomenon but deeply tied to the physical processes of living systems. She proposes we explore the molecular machines of the cell as gateways to this new physics — probing whether coherence/information/agency are fundamental. If true, this would reshape biology, physics, consciousness studies and our worldview.
