That's great news but pointless. We never going to reach the nearest star outside our system until we find a shortcut like a stargate
or wormhole even then we would have to figure out a way how to survive the wormhole travel. Traveling at the speed of light is out of the question. A wormhole is more realistic. I reckon even if Aliens exist they have found a wormhole close to earth and know how to travel through it.
