'''Spacetime''' is a model in [[physics]] that joins the three [[dimension]]al space and one dimensional [[time]] into the idea of [[space-time continuum]]. Combining these two ideas helped [[physicist]]s to make many laws of physics easier to understand, and to explain how the universe works on the big level (e.g., [[star]]s) and small le(contracted; show full)
