Alcubierre's seminal paper showed that general relativity appears to allow superluminal motion. Jusufi, Sakallı and Övgün use an eternal warp drive solution by Alcubierre to study, with the quantum tunnelling method, how Hawking radiation affects an observer inside the drive. Massive vector and scalar particles give the same Hawking temperature, and it is proportional to the warp drive's velocity. This agrees with the statistical Hawking temperature. Including generalised uncertainty principle effects can lower that temperature. Motivated by gravitational wave astronomy, they also analyse the quasinormal modes of massive scalar field perturbations of the eternal warp spacetime. Their analysis shows these perturbations lead to stable modes.
