Space/time has four dimensions? I thought current theory had it somewhere around 11? Which gets to my point that it is easy to conceptualize the three we live in, but when we are asked to make a jump over the fourth(because it is reserved for time) in order to consider the fifth, it makes it harder (and sort of counter-intuative) if we are thinking 1st-spacial;2nd-spacial;3rd-spacial;4th-temporal;5th-spacial,etc.
