Einstein was wrong about black holes, what else?
Einstein's constant is a complicated multidimensional tensor.

People misuse the term singularity all the time. It seems like these guys think singularity is a physical phenomenon. It's not.
It's a mathematical artifact of Einstein's field equations. It's the point where the equations yield infinite density. Something which isn't possible. It's a mathematical limitation of the equations. No one believes there is a point where there is an actual infinite density. It's basically the equations showing - mathematically - where they don't work anymore.What is it then?
That's what renormalization is for.It's a mathematical artifact of Einstein's field equations. It's the point where the equations yield infinite density. Something which isn't possible.

Which is a mathematical gimmick. Bottom line is that singularities are not a physical phenomenon but many people treat them as such. It’s just where the solutions to the field equations stop working.That's what renormalization is for.
It keeps the calculations from running off to infinity.

I disagree with your reasoning. Mathematically, any discontinuity could be considered a singularity. For instance, divide by 0 could happen at a point, but it could also happen over a region. (For example in fiber bundles, in places where there are no fibers).Bottom line is that singularities are not a physical phenomenon but many people treat them as such.
