I am used to witty remarks like:
I have seen better art on napkins, or My dog makes sculptures like that every morning.

One thing about dimensions is that each higher dimension surrounds the one before it in dimensions 1-3, yet when a dimension is so small as to wrap around itself, it really isn't bigger than the lower numbered dimension but still is everywhere around the prior dimension. weird huh

For string theory math to work they say you need about 11 dimensions.
Some super symmetry fans prefer 10 dimensions. Different things leak from one dimension to another such as virtual particles or gravitons.

Now there is even talk that a Lee set of 246 levels is the grand unifying number of dimension like vectors that compose the universe.

Still I would prefer an even 10 or even the Hitch Hikers #42.
