鉴于我们在量子化广义相对论时似乎面临着巨大的困难，我们也许应该考虑引力是一种基本的经典相互作用的可能性。反对这种混合经典-量子模型的理论论据很有力，但并不是决定性的，这个问题最终还是要通过实验来解决。我回顾了一些正在进行的工作的实验测试的可能性，利用经典量子耦合的非线性，这可能有助于解决这个问题。
In view of the enormous difficulties we seem to face in quantizing general relativity, we should perhaps consider the possibility that gravity is a fundamentally classical interaction. Theoretical arguments against such mixed classical-quantum models are strong, but not conclusive, and the question is ultimately one for experiment. I review some work in progress on the possibility of experimental tests, exploiting the nonlinearity of the classical quantum coupling, which could help settle this question.
