Could There Be
Another Direction?
An extra spatial dimension would mean another direction beyond length, width and height. It is not just an unknown planet. The CERN website provides descriptions of theories based on extra dimensions as well as descriptions of potential experiments to search for evidence of them.
As such, my understanding of how I see space has made me wonder what other parts of space are missing from my perception? Physics does not state that there are entities or beings within these additional dimensions. I have written that possibility separately from what the source states about the existence of additional dimensions.
