You mean you have a problem with the concept of 27 dimensions? ;-) The problem with a postulation such as that is that Godel’s Incompleteness Theorem says you need to use 28 dimensions to prove the existence of the first 27. Not on my “worry list” for today.
Worried. Me neither. If it is more than my fingers and toes then it is unimportant. My most immediate concern is work, food, family.
Just like the small ant on an ant hill mindlessly moving that tiny crumb from the sidewalk to the den; day after day after day.
