I am not familiar with tensors and I would like to know if it's possible to understand GR without using them. I imagine we use them to describe four-dimentional space-time, because a regular vector or matrix wouldn't be enough.(adsbygoogle = window.adsbygoogle || []).push({});

Is there an analog of Einstein's equations for a 2D space (plane) and time, therefore a 3 dimensional space-time?
