New Curled-Up Spatial Dimensions to be Revealed at CERN

Some physicists are working to support a new idea called string theory.

Underlying string theory is the radical idea that fundamental particles are not really like points or dots, but rather small loops of vibrating strings.

The theory also implies that besides the familiar three–dimensional world and the fourth dimension of time, there are six additional spatial dimensions! These extra dimensions are apparently 'curled up' so small that we do not see them.

In certain cases, the sizes of the extra dimensions are very small and it will be difficult to obtain direct evidence for them. In others, the sizes are far larger and could be observed at new accelerators such as CERN’s Large Hadron Collider.
