Great reply. I was expecting some attempts to counter the definition. In self driving cars disturbance does not propagate thorough any medium. Matter that constitutes a car is same at all points in time, unless a external disturbance(actions of mechanic, owner) impacts them. In other words a car does not propagate through a medium. Calling car a disturbance itself is a bold claim. I would call it a object or system. Even if it is a disturbance it does not fetch medium. Life forms continuously rebuilds itself with new matter.
Waves can transfer energy without transfer of matter, so is life.
Waves can transfer information without transfer of matter, so is life.
Definition: a disturbance propagating through a medium which has a system that can fetch energy and medium from it’s environment to propagate and thus preserve itself(disturbance).
“Medium” is a important word.
CRNs are great but can we be sure that life is possible only in realm of organic chemistry or even chemistry? What about life we do not know? My definition is compatible when we can take CRN as the “system”. Mine is more abstract than that. My definition can even define life in another universe.
If I had some contacts we could submit the new definition to NASA. At least try to do it (after validating it with someone credible). I am really confidant about my definition and have thought of so many examples to counter myself.
