Abstract
As the Earth, solar system, and our galaxy were seen as central to historic cosmologies, space-time is seen as central to the cosmology and fundamental theories of today. Even those theories that posit "extra" dimensions assume that they are additional space-time dimensions. This essay examines the consequences on a number of fronts of the speculation that space-time is not quite so central or special. Topics such as the arrow of time, time travel, quantum gravity and the beginning of time are discussed along the way.
