Fourth Dimension: Time
A hair was believed to have One Dimension: Length, a Picture Two: Length & Bredth, & an object Three: Length, Bredth & Depth. The Fourth Dimension is a constant at the place of an object called Time. Having introduced a non imagery constant movement can be a Fifth & impact on surroundings Six. There are only Three Dimensions.
If Time is constant when the object ceases or collapses the Fourth Dimension of it still exists when it shouldn't. So temporary movement or impacts are variables also because they may or may not exist in the presence of the object as is true of it's Time Dimension.
How does a Two Dimensional object have a Fourth?
