I thought the meaning of life was negentropy. We seem to habitually build little corners of order in the eddies of the waves of entropy sloshing around. Even just by observing things.
If using entropy emission as the indicator, how would we distinguish the exhaust of life from any other energy source? Wouldn't it make sense to look for pockets of negative entropy or would those be hidden by all the opposite reactions?
Not a physicist obviously!
- pacman2 6y agoYou can only decrease entropy locally by increasing total entropy, hence look for an entropy source.
- ncmncm 6y agoStars are the most productive entropy sources in our Universe. I see some. Now, what?
- pacman2 6y agoI don't think you would look for life in a star. Neither would you look for life in a black hole (that is, as far as I know with basically no understanding, also an entropy source)
- ncmncm 6y agoYet, the only life we know of, in the whole Universe, is so close to a star as to depend upon heat from it.
