Some theories propose many other spacial dimensions.Um, many physicists now disagree with time being a "dimension" in the classical sense, and many also believe it to be a property of the universe and not a fundamental part of the structure. In other words time could sit inside the universe, or the universe could sit inside time as opposed to time being a constrained "wall" of the universe.
Here's a that basically explains the direction of this theory that separates time from spacetime.
That's why I kept it separate from the spacial dimensions. The link you provided says that scientists are abolishing time as the 4th dimension of space. I never said it was a dimension of space...I said there were 3 spacial dimensions and one of time. This is, as I currently understand it at least, still what scientists teach.
