Well Parallel Universes, Multiverses, Anthromorphic principles are all postulates that we possibly can never know. But with the Cosmic Horizon, even tho it is unknowable it does exist because the maths tell us it must be there ... Thats why I find it so weird.

Space is expanding faster than the speed of light. The limit that applies to light and everything that started out slower than the speed of light is not placed on the expansion of space. When space expands between any two objects no 'G' force or acceleration is felt ... such as would be if either of, or both of the two objects were accelerating away or towards each other. Our acceleration is limited to less than the speed of light.
The expansion of space is not an acceleration, even tho objects are receding from each other, and therefore General Relativity places no limit on it at all.
