re: "Hawkings plan is that in only 4367 years at the speed of light, we could possibly wind up there at Alpha Centauri Solar system."

I glanced at the article. I think his plan is to launch a ship in TWENTY years that could complete the voyage in only TWENTY years. So forty years, total. The ship would have a light sail and travel at an appreciable percentage of the speed of light.

I don't think we could build such a thing in just twenty years. I didn't read the details, but I assume we would have a laser pointed at the sail giving the ship a push during most of the trip. I have no idea how it could reach such speeds in such a short time, though.
