**Abstract: **

A spacetime is a 4-dimensional time-orientable Lorentzian manifold that satisfies the Einstein equations. These equations are formulated in tensorial form and its analysis, for various reasons, is complicated. In mathematics and physics, sometimes one can gain some insight of a problem by considering a low-dimensional analog of it; therefore, it is natural to ask if we can do that with the Einstein equations. The goal of this talk is to review some basic facts about the Einstein equations and to investigate whether it is possible to consider a meaningful (1+1)-dimensional analog of them.
