1. The first of these two videos is convinced of a 4th dimension and has some cool visuals to illustrate his theory.  He explains that the 4th dimension is actually traveling across and being able to visualize infinite 3 dimesnions, the same way someone who can see 3 dimensions can visualize infinite 2 dimentional illustrations/planes.

2.  This second video is in the camp that no 4th dimension exists.  He also doesn’t think the other 3 dimensions exist either. (at least not in the way that we perceive them.)  He feels that length width and depth are the same thing and there’s no difference.  What do you think?  I will interject my opinion.  Alone, length, width and depth are the same.  But in relationship to each other they take form and have relative meaning. (that seems obvious right?)

What do you think..who is right?  Or is there a different possibility that infinite dimensions exist and neither of these videos explain it correctly.  Perhaps there is a better theory out there.  Comments and video submissions in the comments section are welcomed.
