Jan 21, 2020 at 17:53 comment added user4552 Singularities mean the value becomes infinite . If you're describing the mathematical definition of a singularity, then this actually isn't correct. The metric is not zero at the black hole singularity, but infinite. This is wrong. There is no particular condition on the components of the metric that defines a singularity. Such a condition is neither necessary nor sufficient.
