> Practical implications?

Using ion propulsion and gravitationally assisted slingshot trajectories, you'd get to Proxima Centauri about 173 days 12 hours sooner, which sounds pretty cool if you ignore that that's 173 days of a 19,000 year trip.

By nuclear pulse propulsion (EDIT: invented, but still theoretical, thanks adrianN) taking 85 years, you'd get there about 18 hours sooner.

Nuclear pulse propulsion is actually invented, we just didn't build it yet.
