I agree with you here. Just I was referring that Black hole mergers is not something that can be taken as an example here talking about singularities. But yes,

I agree with you here. Just I was referring that Black hole mergers is not something that can be taken as an example here talking about singularities. But yes, existence of singularities does not mean a breakdown of GR. It suggests that GR is not a complete theory of gravity and means that ww cannot make a meaningful prediction about behavior of the system at the singularity points. We can even consider that GR predicts singularities when the curvature of the spacetime becomes so strong that it becomes infinite.
