Colonies that far away from the Sun? Unlikely. Mankind can multiply like
rabbits and it would still take at least 300 years to fill up the inner
planets and moons.
Earth is already full, and not more than the tiniest fraction of its
people can be launched into space.
Both of those statements are blatantly false.
We could probably double the population, but Earth is full *enough* by
any reasonable standard. We already use about 40% of the Earth's net
photosynthetic product, so we could double the population only if we are
willing to drive a large fraction of the Earth's species to extinction.
