摘要

We propose a refined version of trans-Planckian censorship conjecture(TCC),which could be elaborated from the strong scalar weak gravity conjecture combined with some entropy bounds.In particular,no fine-tuning on the inflation model-building is required in the refined TCC,and it automatically passes the tests from those stringy examples that support the original TCC.Furthermore,our refined TCC could be consistent with hilltop eternal inflation.
