Hyperspace travel is very complicated, even now.  When we first began using it, even more so.  Contrary to popular opinion, we never actually go faster than the speed of light.  That is impossible.  We simply enter a dimension where light travels faster.  And there is nothing simple about it.  The effect is that we have expanded to the stars as a people.  We are no longer waiting for an asteroid to wipe us out.  We have beaten the Fermi Paradox.
