The Fourth Dimensional Universe [|of Earth Utopia]reflected from [|Quest from Utpopia]

�@In the [|fourth dimension] it is the element of //time// that is added to those of length, breadth and height. For two objects to come into contact with each other (or for two people to shake hands) in the third dimension, they have both to exist simultaneously at the same time of the same day of the same week in the same year. But this is not true in the fourth dimension, where two people shaking hands might not belong to the same era at all. For instance: in the fourth dimension it would be perfectly possible for a person from the present day to shake hands with someone from the 12th century. Similarly, it would be impossible to tell whether the building in front of you genuinely existed in the present day or whether it was the 'continued actuality' of a building that had stood there in the past. Even if it was only a simulacrum from the past, it would look and feel real: it would be there.
