Theworld is the totality of entities, the whole ofreality, or everything thatexists. The nature of the world has beenconceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world asone simple object, while others analyze the world as a complex made up of parts.
Inscientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be".Theories of modality talk of possible worlds as complete and consistent ways how things could have been.Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". Inphilosophy of mind, the world is contrasted with the mind as that which is represented by the mind.
Theology conceptualizes the world in relation to God, for example, as God's creation, as identical to God, or as the two being interdependent. Inreligions, there is a tendency to downgrade the material or sensory world in favor of a spiritual world to be sought through religious practice. A comprehensive representation of the world and our place in it, as is found in religions, is known as aworldview.Cosmogony is the field that studies the origin or creation of the world, whileeschatology refers to the science or doctrine of the last things or of the end of the world.
In various contexts, the term "world" takes a more restricted meaning associated, for example, with theEarth and all life on it, with humanity as a whole, or with an international or intercontinental scope. In this sense,world history refers to the history of humanity as a whole, andworld politics is the discipline of political science studying issues that transcend nations and continents. Other examples include terms such as "world religion", "world language", "world government", "world war", "world population", "world economy", or "world championship". (Full article...)

TheNew 7 Wonders of the World was a campaign started in 2001 to chooseWonders of the World from a selection of 200 existing monuments. The popularity poll via free web-based voting and telephone voting was led by Canadian-Swiss Bernard Weber and organized by the New 7 Wonders Foundation (N7W) based in Zurich, Switzerland, with winners announced on 7 July 2007 atEstádio da Luz inLisbon. The poll was considered unscientific partly because it was possible for people to cast multiple votes. According toJohn Zogby, founder and current President/CEO of the US polling organizationZogby International, New 7 Wonders Foundation drove "the largest poll on record".
The program drew a wide range of official reactions. Some countries touted their finalist and tried to get more votes cast for it, while others downplayed or criticized the contest. After supporting the New 7 Wonders Foundation at the beginning of the campaign by providing advice on nominee selection, the United Nations Educational, Scientific, and Cultural Organization (UNESCO), bound by its bylaws to record and give equal status to allWorld Heritage Sites, distanced itself from the undertaking in 2001 and again in 2007.
