Orienting Space: 3D Travel from Earth, Center of Universe

[express-tl]

I am wondering about the following issue; on a 3 dimensional scale, how is space oriented? For example, if I took a spaceship and traveled straight down from Earth (down referring straight down from the south pole), what would I see? Furthermore, if the center of the universe if defined as one point, what happens when you travel in the opposite direction?

There is no center of the universe, and there is no orientation to the universe. Any direction is equally good as any other (on large enough scales).

As an example, the plane of the solar system is tilted 60 degrees from the galactic plane. Other stars have the planes of their systems oriented and random directions as well, as do galaxies we see.
