A maverick physicist is building a case for scrapping quantum gravity

Gravity might be classical, not quantum, physicist Jonathan Oppenheim suggests

Scientists are developing a theory of gravity that describes spacetime in a classical, or non-quantum, way, yet preserves known quantum effects, such as interference patterns (represented by the striped circle at right) observed in certain experiments.
