2. Here's some info on up to ten
Imagining Other Dimensions by Rick Groleau

For most of us, or perhaps all of us, it's impossible to imagine a world
consisting of more than three spatial dimensions. Are we correct
when we intuit that such a world couldn't exist? Or is it that our brains
are simply incapable of imagining additional dimensions -- dimensions
that may turn out to be as real as other things we can't detect?

String theorists are betting that extra dimensions do indeed exist; in
fact, the equations that describe superstring theory require a
universe with no fewer than 10 dimensions. But even physicists who
spend all day thinking about extra spatial dimensions have a hard time
describing what they might look like or how we apparently
feeble-minded humans might approach an understanding of them.
That's always been the case, and perhaps always will be.

4. Dont you think its rather absurd

to talk about "thinking about extra spatial dimensions have a hard time describing what they might look like".

Looking might be solely a phenomenon of three-dimensional-based sensory function and meaningless above that.

5. No, it is interesting to imagine and do mind experiments, also

from the details the show on PBS went into it seemed many of the other dimensions were at the atomic/subatomic level so "looking" may be more figurative than literal.

7. Umm, what is figurative looking ?

I have a hard time putting those words together without contemplating the term oxymoron

Looking is by definition a sensory activity, not an imaginative one.

8. Relating to the representation of form or figure by drawing as in


The circles represent an additional
spatial dimension that is curled up
within every point of our familiar
three-dimensional space.






Six-dimensional Calabi-Yau shapes
can account for the additional
dimensions required by superstring
theory.

3. there cannot be a single dimension
It would have no attributes.

By the way, there's no number "one".
