Time is not a dimension; it is a phenomena.

Proof?

Think of each dimension as an axis of a graph. In order for a dimension to "Exist", a point on that graph has to be able to move along that axis.

Now any dimension is a subset of the dimensions above it (for example, dimension 1, a line, is a subset of a plane. dimension 2, a plane, is a subset of dimension 3, space. etc.)

So if time is a dimension, it must be a subset of some other controlling factor.


There is no other factor, but there are dimensions higher than 4, thus time is not a dimension.

Also, if time began, then time cannot be a dimension because a dimension must be infinite in all directions.
