What is World?

Below are the few of some popular definition of the WORLD, which is I've read in the book and/or found on the internet.

• universe: everything that exists anywhere; "they study the evolution of the universe"; "the biggest tree in existence"
• people in general; especially a distinctive group of people with some shared interest; "the Western world"
• all of your experiences that determine how things appear to you; "his world was shattered"; "we live in different worlds"; "for them demons were as much a part of reality as trees were"
• Earth: the 3rd planet from the sun; the planet we live on; "the Earth moves around the sun"; "he sailed around the world"
• populace: people in general considered as a whole; "he is a hero in the eyes of the public"
• a part of the earth that can be considered separately; "the outdoor world"; "the world of insects"
• worldly concern: the concerns of this life as distinguished from heaven and the afterlife; "they consider the church to be independent of the world"
• all of the living human inhabitants of the earth; "all the world loves a lover"; "she always used `humankind' because `mankind' seemed to slight the women"
