I think it's because he did believe that (and he may be right, it is so far the best explanation we have despite it shortcommings). The words he uses on the book to describe it IIRC is "shape shifting mollusk", which probably sounds better in German. Most of the models built on it depend on it being a very real thing and it does explain a lot of things: expansion, red/blue shift, background radiation, etc. The big bang as we understand it today requires no only that space can bend but that it expanded faster than light. -- Fernando Rodriguez
