Define this extra dimension fully such that we understand it as well as we understand the dimension you removed from the sphere and then explain to us why we have difficulty accepting it.
Further, your attitude of "define xyz fully so I understand it or I won't accept it [hands in ear] la-la-la" is simply childish. Grow up. There are things about science (which you do accept) that you don't understand and probably never will (ever tried to visualise a four-dimensional cube as Penrose and a few others can?) The point of analogies is to help you grasp the basics of something even when you are absolutely incapable of understanding it but, as I said earlier, it's up to you to make the effort.
Finally, so what if this extra dimension cannot be defined fully by human beings? Since when did we become omniscient?
