I want my world to have an Alcubierre drive for slower-than-light-travel. One third the speed of light will do. Since there is no FTL we don't have to worry about causality paradoxes. However the drive still has problems! They are about radiation.
Hawking radiation inside the bubble will heat the ship and cook everyone inside it. Also on arrival the ship will release infinitely blueshifted radiation and cook everyone at the destination. Is there any scientificaly plausible way to fix these problems and make Alcubierre safe both for ship and its destination?
Maybe it is possible by adding fictional negative energy exotic matter in the story? Maybe some specific spacetime curvature would do? Maybe the problems don't arise at all if we travel at sublight speeds.
Upd.: abovementioned wikipedia article says that there is no problem with Hawking radiation if the bubble is subluminal. But there is still dangerous blueshifted radiation at the destination if I understood correctly: https://arxiv.org/pdf/1202.5708.pdf Or maybe I'm wrong? Any ideas besides careful navigation?
