But the fact, the journey is completely just a fiction and only displayed on the Sci-Fi movie, because we don't have such advance technology yet. The journey is require a highly advance technology such as the propulsion system, the navigation system, the communication system and other system that needed to support the human life out there.
The propulsion of the spacecraft that we already have is not enough to reach the minimum speed that needed to send the vehicle to its destination within the desired time. The chemical propulsion that we have now is just burned out in few seconds during the launch of the spacecraft. what a very short moments. in fact the thrust in that time is will never move the spacecraft in the interstellar voyage. imagine what this kind of thrust can do to a such spacecraft that attempting an interstellar voyage?
