The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts.

In scientific cosmology, the world or universe is commonly defined as "[t]he 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". In philosophy 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. In religions, 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 a worldview. Cosmogony is the field that studies the origin or creation of the world, while eschatology 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 the Earth 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, and world 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...)

Karachi (/kəˈrɑːi/; Urdu: کراچی; Sindhi: ڪراچي; IPA: [kəˈraːtʃi] <phonos file="Karachi pronunciation.ogg"></phonos>) is the capital city of the Pakistani province of Sindh. It is the largest city in Pakistan and the 12th largest in the world, with a population of over 20 million. It is situated at the southern tip of the country along the Arabian Sea coast and formerly served as the capital of Pakistan. Ranked as a beta-global city, it is Pakistan's premier industrial and financial centre, with an estimated GDP of over $200 billion (PPP) as of 2021. Karachi is a metropolitan city and is considered Pakistan's most cosmopolitan city, and among the country's most linguistically, ethnically, and religiously diverse regions, as well as one of the country's most progressive and socially liberal cities.

The region has been inhabited for millennia, but the city was formally founded as the fortified village of Kolachi as recently as 1729. The settlement greatly increased in importance with the arrival of the East India Company in the mid-19th century. British administrators embarked on substantial projects to transform the city into a major seaport, and connect it with the extensive railway network of the Indian subcontinent. At the time of Pakistan's independence in 1947, the city was the largest in Sindh with an estimated population of 400,000 people. Afterwards, the city experienced a dramatic shift in population and demography with the arrival of hundreds of thousands of Muslim immigrants from India, coupled with an exodus of most of its Hindu residents. The city experienced rapid economic growth following Pakistan's independence, attracting migrants from throughout the country and other regions in South Asia. According to the 2023 Census of Pakistan, Karachi's total population was 20.3 million. Karachi is one of the world's fastest-growing cities, and has significant communities representing almost every ethnic group in Pakistan. Karachi holds more than two million Bengali immigrants, a million Afghan refugees, and up to 400,000 Rohingyas from Myanmar. (Full article...)

Seychelles (/sˈʃɛl(z)/ <phonos file="En-us-Seychelles.ogg"></phonos>, /ˈsʃɛl(z)/; French: [sɛʃɛl] or [seʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Seychellois Creole: Repiblik Sesel), is an island country and archipelagic state consisting of 155 islands (as per the Constitution) in the Indian Ocean. Its capital and largest city, Victoria, is 1,500 kilometres (800 nautical miles) east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) and Maldives to the east. Seychelles is the smallest country in Africa as well as the least populated sovereign African country, with an estimated population of 100,600 in 2022.

Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until it came under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to a market-based diversified economy, characterized by service, public sector, and tourism activities. From 1976 to 2015, nominal GDP grew nearly 700%, and purchasing power parity nearly 1600%. Since the late 2010s, the government has taken steps to encourage foreign investment. (Full article...)
