I am glad Dr. Kaku agrees with my thoughts on the 3D world we live in.

I read an article one time on dimensions. An analogy used the article was this:

If you were in your house and decided to walk outside, but you could not look up--you could only look straight ahead of where you were going. And once you got outside, you see a shadow gliding on the ground in front of you, unaware that a cloud was passing over the sun above. So, you don't know what the shadow is. You have no explanation for it because you are missing part of the information you need to determine what it is.

I believe we are slave to this scenerio all the time in questions looming over us about the universe.
