Another issue is one of fuel for propulsion. If you are using rocketry (since we haven't discovered subspace-distortion-based impulse drive or inertial damping), then to get up to near-light speeds, the only fuel that would work is antimatter. Fusion would not work, as the energy released would be about three hundred times less than for antimatter, which would result in needing impractically large (and heavy) fuel tanks.
