As I mentioned before space travel are not characterized by the
speed at which ships move in interstellar travel cannot speak for
periods of years but generations. Typically, when an expedition
reaches its destination, they have passed a minimum of thirty
years shorter trips, traveling at cruising speed fifteen percent of
the speed of light. To make this possible you cannot use any type
of ship, ships large city, with which to carry the same kind of life
they would have on earth, a space community of about ten ships
whose dimensions as are necessary oscillate between two hundred
meters and the kilometer and a half. Of course these ships have a
system of artificial gravity that allow them to feel at home planet,
they would marry have children on board ships and could travel
occasionally to other ships that would form the expedition, to
scroll through space is also feasible scales. A ship can start a
colony on a distant planet than their own and after a transitional
period of a century or two to start again another colonial
expedition to another star with some of the descendants who
would have developed on this planet, for these journeys use
nuclear energy as among the stars is the only energy that can be
used because of the remoteness of the sun, thus the possibility of
sending expeditions to very large distances becomes a reasonable
option. On earth, generations succeed one another without leaving
the planet and this is not considered as something strange, then
travel in mother ships would be exactly the same. Greater energy
savings for all materials be recycled and nothing would be thrown
into space, months these ships would accelerate just a few tenths
of a G (acceleration force) to acquire the necessary speed without
forcing the structure, which would be very slight. In this kind of
society would not exist humanoid robots, because as I told before
the human form is the sum of a body and a spirit, it makes no
sense to wait for a machine that is as a man, unless harbored a
spirit, but that is already the man, robots are rather a way of
playing with the idea of slavery, which from my point of view is
entirely reprehensible.
