# What is the second dimension?

In a 1 dimensional space you would be able to see forward and backwards but not up/down or to the sides. Imagine like a infinitely thin thread. In a 2 dimensional world you would be able to see in front/behind and to the sides but not up or down. It would be like a piece of paper. We live in a three dimensional world. You can see up/down, infront/behind, and to the sides. The term "0th dimension", "dimension 0", etc., can refer to an infinitely small point in space, like a point on the thread earlier described.

### Why is the second dimension flat?

Simple...the second dimension has 2 dimensions. Think of a coordinate plane... it has 2 dimensions... height and width. This plane is the only area that they can be on. If they were not on the plane they would be in a different dimension. So to answer your question... if it wasn't flat... it wouldn't be 2 dimensions. Better yet, the reason why the second dimension is flat is simply because only two vectors exist within…

### Which are the eleven dimensions in universe?

The first dimension is primary (length). The second dimension is secondary (width). The third dimmension is tertiary (height). Those are the 3 basic spatial dimensions. The fourth dimension is time. The fifth dimension is the rotation of primary. The sixth dimension is the rotation of secondary (and primary). The seventh dimension is the rotation of tertiary (secondary and primary). The eighth dimension is the pulse of time. The ninth dimension is the energy radiation of…
