Here’s an incredible Flash animation that will help you visualize 10 dimensions. This’ll probably blow you clean outside your mind for a while: The Tenth Dimension [LINK]

"Just like that flat lander who can only see two dimensional cross sections of objects from the dimension above, we as three dimensional creatures can only see three dimensional cross sections of our fourth dimensional selves."

And I’ve gone cross-eyed.

Here’s a breakdown:

• 1st dimension – joining two points – a single line
• 2nd dimension – Three points – a single plane
• 3rd – Two intersecting planes – Where we live
• 4th – Us + time
• 5th – Us + time + choice, "the subatomic particles that make up our world are collapsed from waves of probabilities simply by the act of observation" – (I’m so glad I read Schroedinger’s Cat)
• 6th – Folding the 5th through the six to jump to a potential new position in the 5th dimension. Not time travel but a "dimensional jump".
• 7th – All possible time lines which could have or would have occurred, ever: Infinity.
• 8th – Joining two different infinities (like 2Dimensions).
• 9th – folding the 8th – traveling through entirely different infinities.
• 10th- All possibilities are contained herein. This is where Strings live.

Ok, so it kind of lost me at the 10th but the 1 through 9 made pretty good sense.
