**Tensors and General Relativity - Explained Fast**

Here's my attempt: Tensors are mathematical objects that are incredibly efficient at describing a material under strain and stress.

You can think of spacetime as a “material” that’s put under “strain and stress” by the presence of mass. So Tensors are all over General Relativity. And the “strain and stress of spacetime” is called Gravity.

If we had a Quantum theory of spacetime it might describe the situation totally differently. But we do not yet have such a theory.
