It would be an awesome sci-fi plot: voyager 1 is captured by an alien race. Goes silent for a while they figure out how to boot it up. Then it starts transmitting the instructions to build a wormhole . Lone engineer who held out hope discovers the signal after the project was mothballed. (sorry this bit stolen from Contact). Or instructions for a hyperdrive.
if the movie contact was made today unfortunately, the signal would have been intercepted by a teenager who the builds the machine to the alien spec in his bedroom with his best buddy from school
