Abstract:

THIS PAPER IS MEANT to show that human expansion into a Galaxy in which life is a rarity will slow to a rate much below that of ship travel, at a distance from the Sun which may be no more than several tens of light years. This will be so even if spaceships capable of carrying small crews at up to 0.5c become available, for it will not be their cargoes which control the exploitation of new sites. It may even be so with faster than light travel.
