Summary
It is commonly held in many philosophy of quantum gravity circles that endorsing Lewis ontology of modal realism is incompatible with endorsing the fundamental physical ontology of any quantum gravity theory. The unsolvable tension would be between the Lewis metaphysical commitment to the fundamentality of space and time and the physical lesson of quantum gravity about the disappearance of space and time from the fundamental structure of the world. In this essay I argue against the idea that the tension is unsolvable. This analysis does not apply to quantum gravity in genera, but only to quantum string theory.
