If you mean that you assume the earth is a cube, then maybe a rocket or a satellite be launched. There may exists an escape velocity, but may not 11.2 km/s. (Just for your reference)
No. There earth is the center of the universe and the stars are just little pin pricks of light on the surface of the dome that covers the earth. So there is "outer space" to fly through. (Somebody was sleeping in their science classes or they would have know that.)
