Astrophysicists have long since postulated that ‘wormholes’ in spacetime – hypothetical topological features of spacetime like a tunnel with two ends each at separate points in spacetime. What is less well known are the – thought to be acid fuelled – postulations of rabbit warrens and badger sets in spacetime. These tend to be hushed up by scientists to prevent panic in the population at the thought of destructive spacetime wars between infinite dimensional space badgers and space rabbits very similar to those fought out by Timelords and Daleks.
