Why?

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
