Singularity at in the formula for gravitational potential energy means that the only other apparently reasonable alternative choice of convention, with for, would result in potential energy being positive, but infinitely large for all nonzero values of, and would make calculations involving sums or differences of potential energies beyond what is possible with the real number system.
