[ExI] The Universe is big - really, really BIG.

Most interstellar ambitions are flat-out impossible without some form of
faster than light drive.

What few theoretically possible ways we know of to achieve this, can not be
developed without the sort of mature outer space industry that seems highly
unlikely to happen without associated human colonization of non-Earth
bodies in our solar system.

Therefore, to reach across the stars we must first seriously begin to
colonize the solar system.
