Usually we assume that there is some new set of laws or some new way of looking at the problem that makes the apparent singularity go away. ...Most people worry about singularities involving general relativity: two examples being a black hole and the singularity that classical general relativity predicts was our universe at the moment it began. If you try to apply the laws of general relativity in these situations you will inevitably find the same 1/x singularities I've been talking about. How are we going to resolve these singularities? We expect quantum mechanics to do the job, since it is the theory that correctly describes physics at small distance scales. Unfortunately, while we have good theories of atomic physics, we don't real have a good theory of quantum gravity.

| | In short then, a singularity represents an infinity and we generally don't think nature is infinite. The problem arises from not having some kind of 'floor' built into a theory that keeps you from taking the limit of 1/x as x goes to zero. The way out is to apply a new theory that has such a floor, such as quantum mechanics or string theory (quantum gravity).}}</ref> According to C.J.S. Clarke, no final satisfactory statement emerges of what a singularity really is like.<ref>{{cite book | | In short then, a singularity represents an infinity and we generally don't think nature is infinite.
