Hi all in a previous discussion a definition of life was given and it is undoubtedly a reasonable definition. However is it not possible that it only applies to life on a certain scale.

Consider the -protein- concept. It appears that the universe does not do the protein thing so it cannot be alive. But much in the universe does fit the definition and all of the creatures that fit the protein definition are part of the universe in perhaps the same way as our cells are part of us.

Perhaps what is needed is a definition of life that applies to the really really big just as in physics there is the need of a way of looking at things that works for the really really tiny?
