论文摘要
我们评论自下而上的差异（即数据驱动，临时）和自上而下（即源自引力相互作用的基本理论）宇宙学模型，其各自的状态，预测能力和生存能力。我们就当前和未来关于通货膨胀，暗能量和重力波的理论模型的研究都应该集中在自下而上的模型上，例如$ f（r）$，horndeski或horndeski或donski或dhost理论，还是量子引力的宇宙学模型。
We comment on the difference between bottom-up (i.e., data-driven, ad hoc) and top-down (i.e., derived from a fundamental theory of gravitational interactions) cosmological models, their respective status, predictive power and viability. We fuel the debate on whether present and future research on theoretical models of inflation, dark energy and gravitational waves should concentrate on bottom-up models such as $f(R)$, Horndeski or DHOST theories or on cosmological models of quantum gravity.
