What would be the properties of a universe with only one spatial dimension and one time dimension? General relativity in 1+1 dimensions is unique since the two curvature terms in the Einstein eld equations cancel. This makes the Einstein eld equations algebraic rather than dierential equations. This special feature can make 1+1 dimensionality attractive as an instructional tool to simplify the mathematics that many beginners nd opaque. We explore the implications and features of the Einstein eld equations in 1+1 dimensions and nd they provide a surprisingly rich and interesting model. We then study an alternate theory and its implications for a potentially stable wormhole solution
