**When General Relativity Fails**

The elegant Tensor form of Einsteins's Field Equations (EFE) masks a critical property - they are basically differential equations of derivatives with respect to spacetime i.e. with respect to the x,y,z and t coordinates.

But derivatives are only valid for "very smooth" functions. Meaning if spacetime becomes "chunky" EFE will not apply - for the simple reason that the derivatives are not defined.

At some point this chunkiness of spacetime will become apparent - the center of a rotating black hole is probably an example.

So, it's not that you can't solve EFE in this situation - it's that you can't even write them down!!!!!!!
