How would the 5th spatial dimension exist without time? All spatial dimensions need time otherwise it is just a standstill.

Officially time is not the 4th spatial dimension. Time is an entirely separate temporal dimension. Yet space and time are mutually dependent. So much so that it exist as a foam called spacetime and wherever you go in the universe, the speed at which you travel will effect the time you experience. That is mind-blowing to me tbh!

But our understanding of the mathematical constants and laws in nature could be misinterpreted and you could be right in that "it is barely comprehendible to us. We kind of get it and can somewhat use it, but we have no real ability to navigate through it. "
