Well it may sound strange, but scientists believe that some time in future it may be possible for human beings to be born in space and live their whole life there. It has been the quest of man to discover the nature of the universe beyond earth. Since ages unknown, people have dreamed of leaving their home planet and exploring other worlds. It was in the 20th century that dream became a reality. Today even living aboard the orbiting space stations for months at a stretch is possible.
For people who will have left Earth to live in space will live in artificially created colonies. These colonies will have a conducive atmosphere for survival, will be like a gigantic spacecraft, many kilometers across in which there could be whole cities, together with fields and lakes.
These colonies would grow their own food to support a human population of thousands of people. They could make special space products to trade with earthly beings, or may be offer space holidays to earth tourists. It all sounds like a scientific fiction, but scientists have actually designed viable space colonies that may one day really exist!
