How long would it actually take a human-made spacecraft to travel one complete light-year?
Tonight, we follow that journey from Voyager 1’s seventeen-thousand-year crossing time to ion engines, nuclear propulsion, solar sails, laser-driven nanocraft, and the extreme possibility of continuous acceleration.
Along the way, we explore the Oort Cloud, interstellar navigation, communication delays, spacecraft endurance, relativistic hazards, and why the answer could range from the year 19,661 to only a few years after launch.

If we are going 186,000 miles per second it would take one year!
Who asked this question anyway?
At this rate seen this planet has to idea how to co-exist with each other long enough space travel for 9000 odd years is never going to happen. Leaving this planet with everything you need to exist to explore nothing seems bizarre.
