560 light years
They ask David how far away Phaelon is and the screen prints 560 light years. They ask how long did it take to get there, the screen shows 2.2 solar hours.
That doesn't make any sense.
Even if the ship was traveling at near light speed, it would take more than 560 years (with respect to Earth) to go to Phaelon and another +560 years to get back to Earth.
Did the ship use a wormhole or was it going faster than the speed of light?
