Simplified toy theories abound in theoretical physics. These toy models are ex- tremely useful. An example is N = 4 supersymmetric Yang–Mills theory. In this toy model alone, tens of thousands of papers have been published, some cited thousands of times. This essay proposes that physicists consider studying "N=4 General Relativity" as a toy model. This 'Only Gravity' toy model uses Einstein's field equations on their own in the hope that ignoring complicated interactions of gravity with other fields (electromagnetism, etc) and physical theories (quantum mechanics, QFT, etc) may paradoxically help us understand more about quantum gravity.
