Simple and double walled Krasnikov tubes: II. Primordial microtubes and homogenization

Abstract

First we take a look at the behaviour of geodesics initially directed at a Krasnikov tube of small mass. We show that superluminal shifting is a generic property of geodesics aimed at the tube, not just of those entering the tube by its mouths. Then we show that if present in sufficient numbers, microtubes could be put to task in achieving an inflationless predecoupling homogenization of an open neighbourhood of our particle horizon.
