Suppose you got into a spaceship and flew in a straight line, forever and ever, where would you end up?
Assume, for the sake of argument, infinite fuel and air and food, and you lived forever. Would the ship just keep flying farther and farther away from its startng point (the earth in the Milky Way galaxy) in a straight line for all eternity? Or will it eventually “circle around” to return to its starting point?
