There is no other way to create another 90 degree angle. If there was then we would live in a 4 dimensional universe but we don't because there is no way to create another 90 degree angle, there are only three and it is the emperor's new clothes fairy tale to say otherwise. Why hasn't anyone simple stated that here lies the problem and it is not a valid assumption to assume another 4th to infinity dimension.

i look at this very simply,

take your piece of folded paper and move it to the other side of the table. You still have the same dimensions, but to move the structure requires time. So you end up with the same physical dimensions but in a different spacetime location (frame of reference) from the original position. This difference accounts for the 4th dimension of "time".

Even if you did not move the paper structure, say a 12" cubed box. You construct it and place it in the closet. The next morning you check and hey it's still there, it hasn't moved an inch! But that is wrong. The box may be thousands of miles from the exact location in "spacetime" you placed it originally. You don't see the difference because you are in the same frame of reference as the box, but you also have moved in spacetime, right along with the box.

Space keeps things apart, time keeps things from happening all at once. 4 dimensions (at least).

It is very important to understand this "marriage" of space and time as all science is based on those four fundamental dimensions (measurements).

As to the eleven dimensions in string (m) theory, this may be due to the mathematical precision strings are "permitted" to vibrate. In order to be able to vibrate at all primary and harmonic wavelengths, the 3 normal spatial dimensions may not allow for sufficient accuracy of movement or end up with conflicting "wave interferences".

I am a layman myself so i'll await correction from "learned minds', but i hope at least my reasoning is fundamentally logical.
