A few mails back the (IMHO sensible) idea was mentioned that supersocieties have space as their living environment and only use planets to get building materials.

If that is the case, why should they be in a hurry when they're travelling from one star to another?

The obvious answers would be population expansion or the 'need' to expand their living quarters or get material for scientific tests.

But that answer can be effectively countered because: - advanced species very probably master birth control - advances in science and building means you can do more with the same amount of material, so you don't usually need to get more and more raw materials - a huge ecology bubble needs a very good social system to start with -- and such a near-perfect society probably doesn't have the same urge as we have to have more and more possessions
