   For anyone who has read the math/physics short story (non-fiction)
'Flatland', it is known that time is certainly not the forth dimension.
If indeed any forth dimension exists, it would be an extension of the
third dimension, much in the same way that the third is an extension of
the second. Just because we cannot conceive of the direction that one
expands in after length, width, and height, does not mean that it isn't
there. I very strongly encourage everyone who is interested to read
both Flatland (any library will have  it), it is very short and very
nontechnical. Not only that it is even entertaining. Someone once told
me that there was a technical follow-up called Physics of Flatland.
