- 2004, Barton Zwiebach, A First Course in String Theory, →ISBN, Figure 23.1, page 519:
- A one-loop Feynman graph that represents a virtual process. In the limit in which the virtual process involves short distances or high momenta, one may find an ultraviolet divergence in the corresponding amplitude.
- 2017, David F. Chernoff, S.-H. Henry Tye, “Inflation, string theory and cosmic strings”, in Wei-Tou Ni, editor, One Hundred Years of General Relativity […], volume 2, →ISBN, page 275:
- Since current gravitational observations are insensitive to quantum effects, one may wonder why an ultraviolet completion of the gravity theory is needed if inflation, in fact, occurs several orders of magnitude below the Planck scale.
