Outer space

Outer Space is the term for the massive amount of empty space surrounding the entire World of Avatar. It takes up the entire universe.

History
Outer Space was first seen in "The Guru", where Aang had a vision of him walking across a bridge of energy to reach his Celestial Spirit, thus gaining him mastery over the Avatar State. before he can reach his spirit, he senses Katara is in trouble, ergo he leaves to save her, causing the bridge of energy to disolve away. It is seen again in "The Crossroads of Destiny", where Aang succeeds in merging with his spirit. He soon falls down again when Azula bolts his real back with lightning.

Outer Space is seen briefly in Sozin's Comet, Part 2: The Old Masters, where Sozin's Comet was shown skimming Earth's atmosphere.

Description
Not much is known about Outer Space, though it can be assumed it is like Outer Space in the real world, and is more spiritual than scientific. Gravity likely does not exist in space. Objects such as meteorites and comets roam through space. An example would be Sozin's Comet. It is unkown if other planets, solar systems, and galaxies exist as they do in the real world, though it is highly likley. many stars are located in Outer Space. The stars may be made of the same gasses that they are made of in the real world or made of any gasses at all.

The Sun and Moon also exist in Outer Space. The planet of Avatar does seem to orbit the Sun as Earth does. The Moon seems more complicated, as it exists from the Moon Spirit's presence. It can dissapear if the Moon Spirit is killed, which stresses the fact that Outer Space is more of a mystery than a scientific study. It is unkown if Super Novas and Black Holes exist in Outer Space, though it is likely due to the fact that stars exist.

It is possible that some spirits thrive in Outer Space, such as the Moon Spirit, Yue. Space exploration does not seem to have occured yet in the Avatar World, and likley will not occur for a long time if ever.
