But if such a real physical pink elephant can't exist, that means that it is not a logically consistent concept to begin with. If one starts from a logically consistent system, then one can always find a physical system whose equations of motion realize it, it will then exist in a generic multiverse scenario.

That's my point. Anything 'could be' if the only constraint is logical consistency (not self contradictory). But in the sense of 'be' that requires a universe and observers there appear to be other, nomological constraints. So there could be an animal that looks superficially like and elephant and lives on a planet who's atmosphere is as dense as water and is pink. But it couldn't also have the same DNA and metabolic system as and elephant. So it would only 'be a flying pink elephant' because we use the words to denote a certain similarity in appearance.

Question: would such "anything" be topic for this physicalist-based conventional EVERYTHING List? Q-2: are OUR colors defined for different physical circumstances as well? BTW - IMO flying is not restricted to a conventionally called 'gaseous' medium, so 'swimming' can be considered an alternate for flying. - PINK Whales? <G>
Rem: of course 'they' all exist - if not otherwise: in our mind.

Flying pink elephants can e.g. exist on planets with an extemely dense atmosphere, there was a NGC documentary a few years ago about this topic, it was
        suggested that you could have flying whales on such planets.


Could you identify them as elephants and whales by their DNA? Could the elephants
    be pink?
