I would venture to state, in using a logical extrapolation, that the firmament that surrounds us tends to distort distant images, and that all humanoid life in the Universe resides in flat plane realms like this one.

Which means, for example, that the three "worlds" in the home system of The Reticulan Empire, the Zeta 2 Reticuli System, a binary star system, are all flat plane realms as well.
