Four dimensions, actually, including time.
In any case, we are completely unable to perceive other dimensions, even if they did exist. With everything in the physical world describable in terms of the x, y, and z axes and time, what possible use is there for another dimension?
God created the flesh body, housing the soul/spirit intellect that is weighted by gravity cannot physically see other dimensions. Well, unless there is a purpose for any to be shown. But to say 'we are completely unable to perceive other dimensions,' is questioned by the Gospel. Christ was visible in His transfigured body, and yet in that body He went through a physical wall.
Or might mean you get “there” faster.
Speak for yourself.
Okay, good, was thinking time would be a fourth.
would you not then need 5 or 6 dimensions if you include time so as to have a beginning and ending element in your field set other (x, y, z, t0, time_start, time_end).
Thankfully linear algebra doesn't care about the number of dimensions in the so the whole premise of the question is probably wrong.
The other 11 dimensions describe the topography of this universe and could make it possible to transit to another universe or to transit from one pint to another instantaneously in this universe ... but you’d have to be really, really small ...
