It is not so much a matter of figuring how to do it as one of figuring out how to convince the world to invest a large portion of it's money and minds for generations. A spacecraft (presumably a nucleur rocket, though there are other options) would have to be built in orbit, large enough to carry several thousand colonists on a journey only their children will see to it's end. In a few thousand years these colonies build their own spacecraft and the process repeats it's self. This is all gonna cost a buck or two...
