- The paper challenges the common belief that quantum gravity is necessary at the Planck scale.
- Five arguments supporting quantum gravity at the Planck scale are examined and found insufficient.
- Dimensional analysis, quantum black holes, and generalized uncertainty principles are among the arguments critiqued.
- The nonrenormalisability of quantum gravity is the strongest argument but relies on an unwarranted assumption.
- The conclusion is that current theories do not predict quantum gravity at the Planck scale.
