Summary

Diagrams of three possible geometries of the universe: closed, open and flat from top to bottom, corresponding to a density parameter \Omega_0 which is greater than, less than or equal to 1. The closed universe is of finite size and, due to its curvature, traveling far enough in one direction will lead back to one's starting point. The open and flat universes are infinite and traveling in a constant direction will never lead to the same point.

Wikipedia for Schools is one of SOS Children's Villages' many educational projects. SOS Children's Villages believes education is an important part of a child's life. That's why we ensure they receive nursery care as well as high-quality primary and secondary education. When they leave school, we support the children in our care as they progress to vocational training or higher education. Have you heard about child sponsorship? Visit our web site to find out.
