DEF

The first obstacle ... in extracting realistic particle physics from string theory is that quantum mechanical consistency of string theory requires a spacetime of ten dimensions ... While the thought of other dimensions beyond the four (three space plus one time) that we observe seems far-fetched, extra dimensions could have easily escaped detection if they are small enough. This idea is called compactification.
