english: And we can ask all those questions because there has been a revolution in our understanding of what a habitable planet is, and today, a habitable planet is a planet that has a zone where water can stay stable, but to me this is a horizontal definition of habitability, because it involves a distance to a star, but there is another dimension to habitability, and this is a vertical dimension.
non_english: Možemo da postavimo sva ova pitanja zbog revolucije u našem načinu shvatanja toga šta je zapravo planeta i danas, naseljiva planeta je planeta koja na sebi ima zonu gde voda može ostati stabilna ali po meni to je horizontalna definicija naseljivosti jer uključuje i udaljenost od zvezde, a postoji još jedna dimenzija naseljivosti, a to je ta vertikalna dimenzija.
