There are probably 'higher' dimensional aspects to the situation. Whatever that means? The place is quite mysterious, and 'we' are quite 'stuck' 'herein'. Other than that 'we' have 'our' model stories, perhaps that's all 'we' can handle. What is anything in 'itself'? More mystery.
BTW, I resent the shallow understanding with which 'we' seem to be stuck.
In the meanwhile, 'higher' dimensional measurements and considerations are very interesting. Even negative results, such as the 'recent' studies of gravity over millimeter distances. Some of the 'space' studies are 'higher' dimension oriented. String theory, though surprisingly productive, remains very non intuitive.
