The spatial dimensions—width, height, and depth—are the easiest to visualize. A horizontal line exists in one dimension because it only has length; a square is two-dimensional because it has length and width.
Add depth and we get a cube, or a three-dimensional shape. These three coordinates are used to pinpoint an object's location in space. Once we know a dot's altitude, longitude, latitude, and position in time, we have the tools needed to plot its existence in the universe as we know it. String theory, also known as "superstring theory," aims to unify two main theories describing how the universe works: general relativity which applies to very large objects and quantum mechanics which applies to very small ones.
After coming up with a theory that hinges on the existence of 10 space dimensions, string theorists then had the job of explaining where those new dimensions were hiding. Their answer: They are just as real as the "big" dimensions we can see, but the extra dimensions are curled up so tightly that they're too small for us to notice directly. Our basic understanding of physics makes this hard to process, but string theorist Brian Greene does a great job of framing the concept in terms most people can understand.
In his TED Talk , Greene compares these invisible dimensions to the cables connected to telephone poles: From a window, a wire looks like a one-dimensional line.
