I posted this here because seemed appropriate for theory development. As I am interested in physics thinking on this subject. How does physics apply to living organisms? Are any of the physical laws relevant? Do conservation laws apply? How can physics relate to say a dog or a cat? How does GR or Sr apply to annimate objects? Or does it? The reason I ask these questions is that when we think physics we tend to only think about "the solid stuff" or "the hard stuff" but how do we apply physics to a living organism? Until life is included in the physics picture can we say we are close to the truth?
