I have heard different and seemingly opposingly different theories about the fourth dimension and it annoys me.
One theory I heard is that the fourth dimension is time/anti time, the fith dimension is other universes branching off our own, and the sixth dimension is travel between other dimensions.
Then I also heard that the fourth dimension is just another dimension, that we can't see because like if we were all 2 dimensional, we would not be able to see the third dmension. And that a four dimensional cub would look like This
which is right? or are either right?
