700 years would be twice light speed; at 0.5c it would be 3000 years.

- SolarNet 10y agoThe math is wrong but not quite in the way you figure it. His point was that if the spaceship launched at the same time as the light left and the spaceship was traveling at 0.5c. So it would be 1480 years again (1/0.5 * 1480 - 1/1 * 1480).
