This is my definitionist term for a parallel earth, galaxy, or what most call a universe. Being that the universe is infinite.

Statistics alone are enough proof to say without fail, that there are other earthlike planets identical to ours. Possibly even in the milky way. Unlikely in our galaxy though.

A dopplëganger Galactical Orient can be just an identical solar system, or just an identical planet in a nonidentical solar system or galaxy.
