Every time I see a representation of a supercontinent like Pangea I immediately wonder what's on the other side of the planet. It seems unbalanced to me. Literally too. I find it hard to believe that there would be nothing but open ocean on the other side of the planet. I would think that there would be another continent on the other side too. Do we think that the somewhat evenly distributed landmasses as they are now is just co-incidence?
